Robotics startup (STEALTH + YC S26) | Principal Mechanical + Firmware + SWE | SF Bay Area | ONSITE | $200–250k + 1–2% equity + benefits
We are a new robotics company based in Palo Alto, California, building wearable robotic devices that improve the endurance of humans on foot.
Our first product is a lightweight, bilateral hip product that reduces the physical cost of carrying heavy loads over distance, allowing personnel to move farther, carry more, and arrive at the objective less fatigued and more effective. The company is early but already operating in the field, with a direct feedback loop in the most demanding conditions imaginable.
We are backed by Y Combinator and a group of leading deep-technology investors.
We've recently moved to the Bay area to grow the team, and are hiring three lead engineers who will own product/ their domains, and have full authority with no inherited design decisions and no one between them and the problem. What you build will be worn in weeks by real users:

Distru is the #1 ERP in the cannabis industry, $3B in annual sales flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.
We're profitable, stable, and growing — no runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).
Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce — a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.
The role: You'll own mission-critical, full-stack features end to end — planning, design, implementation, testing — across every part of the product. You might work on AI-native features (order/purchase intake, smart product matching, systems that learn from user feedback), Distru Commerce storefronts and ordering, manufacturing and distribution workflows, cultivation mobile tools for the floor, or compliance integrations with state systems like Metrc. It's a high-ownership role: you'll partner directly with product, design, support, and our C-suite, and you'll get customers writing you personal "thank you" emails.
Im the hiring manager - some of the product highlights under the team's scope:
- Grafana Assistant: the actually useful AI assistant that helps you do everything in Grafana; it works everywhere - even in OSS!
- Investigations: background agents for investigating issues
- Grafana Cloud CLI (GCX): CLI covering the entire surface of Grafana Cloud/OSS APIs; plays great with Claude Code/Codex/Cursor and the Assistant
- AI Observability: helps you build useful agents and then lets you monitor, eval and improve how they behave
- O11y Bench: compare agents' performance across a range of observability/SRE tasks
Our pace of development and innovation is RAPID - the AI Observability product went from being the winning hackathon project to public preview in 6 weeks. We are at the cutting edge here - we are experimenting with autonomous (but safe) SREs, an agentic platform, improving agentic dev experience with o11y insights, fine-tuned LLMs for specific tasks, and more.
We are looking for highly ambitious engineers who have a great sense of ownership, are all-in on agentic development, and have previously built and operated systems at scale. We are all full-stack and love initiative- we would love to talk with you _especially_ if you built something out in the open!
I'm looking for someone who understands C/C++ and would be willing to learn C++20. The codebase is small (<100k lines), and you'll be working with me to complete a project. I'll help you learn C++20 and various tools. I don't mind if you know very little, but you'll need to understand every line you write and be able to explain it to me. You'll be expect to problem solve alone.
Email me something to look at. JurassicTyler@proton.me I don't need a resume. I rather look at code you written entirely yourself. Pick a specific file you think is interesting.

RedLine Solutions is hiring a fully remote mid-level C#/.NET developer. We are looking at an early September start date. I'm posting this way ahead of time to try something weird: If you are an interested developer, please do NOT contact me directly. Instead, find someone who will vouch for you and have them send me your resume`.
No, I'm not on some kind of power trip (yet). I just got my fill of automated application spam a long time ago; the tales I could tell. This is my modestly creative attempt to circumvent the AI's. Might be good practice for SkyNet, eh?
We are not looking for a know-it-all. Instead, we desire a "wants to learn it all". We're a small company, but our System Architect / Dev Lead is seriously a unicorn. If he mentors you for a year or two, your career is golden. Back in the day, I secretly believed I was one of the best around. Then I worked with Stephen. I've learned a ton from him, and I'm his boss.
We're a small, agile, creative and laid-back team who work hard but value work-life balance. I take great pains to make it so. If you're smart, work hard, and love writing software, ask a friend or former boss to vouch for you and have them send your resume`.

Mitty | First Engineer| Honolulu, HI or REMOTE | Full-time | Base + Founding equity
Hi I’m Devin.
Do you love hard problems? Do you find yourself thinking about new ideas on a daily basis? If so, you are the person I’m looking for!
Biz overview:
Our phones camera rolls have 10,000+ photos and videos… most aren’t good but some are. Mitty analyzes the content, creates the idea from what exists, and edits the footage → presenting you with a finished video to post on social. Pretty neat huh! Well, that’s the idea. Also, hard to pull off, which is why I need you!
I'm the founder. You will be the first technical hire and own everything technical — pick the stack, make the architecture calls, write the code, and hopefully stay lead engineer for the life of the company. I’m technical but not good enough.
90-day goal: ship v1.
Helpful: ML/AI + video understanding / computer vision; mobile (iOS preferred); video processing/editing pipelines; comfort wiring up LLM + vision APIs (Anthropic, OpenAI, etc.) and can workout without micro mngmt.
What I’m trying to build: category leader in AI video creation around pre existing content (different than opus who is more podcast style), built toward an acquisition or Series B in ~3 years (Adobe, Canva, Meta, Google are the obvious acquirers).
Comp: $150k base (or more depending on skill) + performance bonus + founding-level equity scaled to experience.
Ps. I don’t expect you to be THE Expert at all of this. Just someone who is good to workout with and likes figuring things out.
Factory | Security Engineer | ONSITE, San Francisco, CA | Full-Time
- also -
Factory | IT Operations Specialist | ONSITE, SF, CA | Full-Time
My team at Factory's growing. Come work with me to beef up 1) our security stance, and 2) our IT program. We're growing rapidly and I want to get ahead of scaling issues. You'll work directly with me, with agency to define and evolve your own role. Today we need hands-on-keyboard IC work. Want to grow that into a director-level role? This is the time to join.
My short endorsement: I love coming to work every day and building the future along with a lot of the smartest people I've ever met, with a workplace culture that I'm proud to be a part of. You should come help me make it even better.
Quantum Rise | Chicago or NYC (preferred), Remote for the right candidate | Full-time | No visa sponsorship | https://www.quantumrise.com/
Quantum Rise is an AI-forward consulting startup serving the mid-market in the US. We see companies in multiple industries struggling to understand how to leverage artificial intelligence in their day-to-day operations, trying to understand what their existing workforce now needs to know, or trying to understand whether they're about to be disrupted and need to change how their existing processes work. Many have business problems which "traditional" machine learning could help with even prior to the current GenAI hype cycle, but for whatever reason hadn't prioritized doing until now. Many have employees looking to incorporate agentic AI safely and effectively across different business areas. We try and help getting a handle around these issues and designing outcome-driven solutions.
Agentic AI Solutions Manager: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply embedded in agentic engineering practice across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners and need help navigating a new, powerful scary world.
AI Solutions Engineer: You're someone who has experience across the entire spectrum of applied automation, machine learning and agentic engineering.
We think of these two roles as complementary -- agentic AI solutioners help clients understand the forefront, whereas pure AI solutioners help them pick the right solution not the one they saw in the news.
Both are front-facing development roles for someone who loves both tech and tackling real business problems. We love people with prior experience in multiple industries.
To apply, send me an email at julian.berman at quantumrise.com, mentioning HN and including your CV.

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.
Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.
We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.
In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.
We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~550). Now we’re scaling the platform.
Axle Health (health tech x logistics) | Backend, Interoperability, and DevOps roles | ONSITE: Santa Monica (5 days) | https://www.axlehealth.com/careers
Home-based care should be the default in American healthcare. It isn't, mostly because the technology has never been good enough. Patients heal faster at home, it costs a fraction of facility-based care, and it's what people actually want — yet the industry runs on phone calls, spreadsheets, and systems built in the 90s. We started Axle Health because we think that's fixable, and because the stakes are high enough that it's worth doing right.
We're Axle Health, and we think in-home care deserves world-class technology. We're building the operating system for home-based healthcare — the scheduling intelligence, the clinician tools, the logistics coordination — everything that has to work perfectly so a clinician shows up at the right door at the right time with everything they need. It's a hard and important problem, and we're just getting started.
The complexity is real: real-time scheduling optimization across dynamic clinician networks, last-mile logistics that make Uber Dispatch look simple, integrations with every flavor of EMR and payer system you've never heard of, mobile-first tools that have to work in spotty cell coverage in someone's living room, and the compliance surface area that comes with handling PHI at scale — we need to build it all, and we want people who think this stuff is genuinely fun.
Currently hiring Senior Software Engineers (7+ YOE) for:
Ecosmic is on a mission to reduce threat exposure in space by building software for Space Situational Awareness. To achieve this, we built a team of flight dynamics engineers and computer scientists to build & package in-house algorithms into easy-to-use, reliable, and secure products. As an example, our platform recently allowed us to identify a series of close approaches in GEO involving Russia's Luch/Olymp-2 and a Western telecommunications satellite, possibly attributed to SIGINT activity.
We're hiring a Senior DevOps Engineer (strong mid-level candidates are welcome too!) to aid the effort of unlocking on-premises deployments of our algorithms with Kubernetes, and to contribute to the evolution of our platform.
Our stack includes Python for backend services and high-level algorithm tooling, C++ for performance-critical components, AWS for cloud infrastructure, and Terraform for IaC. We currently use managed serverless services, and we’re beginning a gradual migration from C++ to Rust for its reliability guarantees.
You’d join a team of three software engineers who love working in such a fantastic domain. I currently take care of most of the infrastructure work with the team, and we’re looking for someone who can help us tackle this new challenge.
Hey HN! Air Space Intelligence (https://www.airspace-intelligence.com) is hiring in Boston. We're a frontier AI and product company for critical industries and defense, backed by a16z.
Last week, the FAA awarded us a 12-year, $875M contract to build FMDS and SMART - the flow-management and airspace optimization systems that will become the technological backbone of the FAA's Air Traffic Control. What we ship in the next two years will define how this country moves through the sky for the next fifty.
At the core is one of the largest real-time optimization problems in the world: how do you safely sequence ~40,000 flights/day while routing around weather, military airspace, equipment outages, and constant real-world churn? The system has to be right every time, and reliable at scale.
We’re building a national ICHRA platform at the intersection of healthcare, fintech, compliance, and AI.

We’re looking for engineers who enjoy:
* Turning ambiguous problems into production systems.
* Owning outcomes, not tickets.
* Working across product, architecture, and implementation.
* Reviewing and improving AI-generated code.
* Shipping quickly without creating a maintenance disaster.
Requirements:
* Strong Python, TypeScript, or equivalent experience.
* Strong engineering judgment.
* Strong communication skills.
* US residency.

Rho is the modern banking platform built for startups: open accounts, issue cards, manage expenses, pay bills, and close the books in one connected platform with real human support.
We're hiring engineers who want to own problems rather than be handed a slice of one. You'll scope work, write the code, ship it, and sit in on customer calls to understand what actually needs to get better. If a problem touches the frontend today and the backend tomorrow, you go where it goes.
We're looking for 5+ years of engineering experience in a fast-moving environment, comfort working across the stack, and real daily AI fluency. You'd rather get something in front of a user than spend another week making it perfect in a doc.

Friendly Captcha is a growing, profitable, fully bootstrapped company. Our revenue mostly comes from medium to large European enterprise and governments. We have the feeling we can make ourselves known better to engineers and other builders to gain more bottom-up growth.
We're looking to strengthen our team with someone who will be focused on our Developer Relations (DevRel) and general marketing activities. We're a startup and this is a pretty mixed role that's hard to describe in one or two sentences. It ranges from technical writing through building specialized tools and demos to support getting the word out.
CoVar is a small R&D company specializing in AI/ML and software development for defense and healthcare. Bootstrapped and profitable. We're looking for a jack-of-all-trades who can: prototype computer vision algorithms, build Python web services, wrangle large sets of data from disparate classes of sensors, ... any or all, with the only hard requirement being eagerness to learn.

There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Munich, Germany | Remote (CET, overlaps US mornings) | Freelance / contract only, not seeking employment
20+ years across product, UX and frontend, now doing user-facing AI engineering.
What I do best right now: you shipped an app fast with Lovable / v0 / Cursor and it works, but it looks and behaves like the AI default. I take that codebase and make it actually usable and on-brand. Real design system in code (not a Figma file nobody maintains), consistent components, the polish and interaction layer that makes it feel like a product instead of a prototype. Done-for-you, in your repo.
I also help teams that already build with AI but get inconsistent, off-brand results, via a hands-on workshop / masterclass, so your people can produce in your own style instead of getting generic output.
Tech: React/Next.js, TypeScript, Tailwind, design systems / design tokens, Figma, Claude Code + agentic workflows.
WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in: surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re looking for senior software engineers on the frontend to help build the future of our platform: transitioning us to a component-based system all the way through to building beautiful pages that visualize the story of ownership, power, and influence in the Chinese corporate world.
For the frontend we’re looking for significant React experience as well as experience with at least one React framework, plus prior experience building or contributing to a component-based design system & data viz work. At least 5 years experience with 8+ being a more likely level for this person.
We’re also looking for a machine learning engineers to level up our entity resolution algorithms and expand our use of LLM technology - for that role we’re looking for 4 years experience with training and deploying ML models in clustering problems, so either knowledge graphs, entity resolution, recommendation engines, cohort analysis or outlier/anomaly detection.
In both cases you’d join an awesome, tight-knit group of great people who are working on real-world problems with big impact.
Or you can reach out to me directly at leo.green@wirescreen.ai - I lead recruiting here at WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.

Kinelo | kinelo.com | San Francisco | Onsite (with a bit of flexibility)
Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.
We're hiring for two roles right now:
- Product Engineer / Senior Software Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market?
- Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast.
Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).
Please email us at jobs@kinelo.com.
If you want to stand out:
- For the product engineer role, tell us how you think the job of a software engineer is changing.
- For the GTM role, tell us about a time you got massive results with limited resources, all through your ingenuity, creativity, and hard work.

I'm Ketan, Head of Engineering at Credo. We're a seed-stage, HIPAA-compliant health-tech company fixing one of healthcare's dumbest problems: getting the right patient data to the people who need it. Billions of pages of medical records still move by fax every year — causing care delays, admin overload, and dangerous gaps in what providers know. Our AI platform gets clinicians the patient answers they need fast. We have paying customers using it daily.
This is an early engineering hire on our Platform team (5–7 people), reporting to me. You'll work the full stack, shape our architecture, and ship to real users every week. High ownership, lots of surface area, frequent collaboration with our ML team.
Stack: Python/Django, Postgres, Vue, Temporal (for our patient-ingestion pipeline and long-running workflows), Google Cloud, and a mix of AI models (mostly Gemini + OpenAI). No prior Temporal experience needed, just enthusiasm for it.
How we work: strong code-review and pairing culture, serious about testing, async-first with a single daily sync, and we've fully integrated plan/spec-based AI tooling into our workflow (Claude, Cursor, CodeRabbit, Copilot — your choice).
Looking for 3–5+ yrs full-stack experience, solid Python + a backend framework, comfort with relational DBs, a modern JS framework, real testing chops, and someone who thrives with ambiguity and owns problems end to end. Healthcare/FHIR/HL7 and AI-feature experience are nice-to-haves, not requirements. Must be in/near NYC for the weekly in-person day.

Komodo Health | Full-Time | $200–298k + equity | SF/NY (a few days a month) or Remote US | Can sponsor/transfer
Healthcare in the U.S. is a mess. Komodo Health is fixing that—with data. We've mapped the patient journey across the country to build the most complete picture of disease burden and treatment gaps. Our customers are pharma, payers, and health systems who actually want to do something meaningful with that information.
We have an exciting project, where we are building a custom, healthcare data specific compute engine that can be orders of magnitude faster than any analytics solution out there.
We're looking for a Staff-level Data Software Engineer (emphasizing the importance of both data and software here!) to work on this project at the core of our platform. This is a data-engineering problem solved with real software-engineering rigor: you'll be designing the data structures and query systems that make analytics over massive healthcare datasets feel instant. Not wiring up someone else's pipeline DAGs — building the engine underneath.
It's demanding, low-level, performance-obsessed work, and correctness is sacred. If you care about where the microseconds go and refuse to trade off getting the answer right, you'll fit in.
The team is very small, and we intend to keep it this way. If you are interested in heads down work with a group of high caliber like-minded folks, this may be perfect.
What we're looking for
- Staff-level software engineer with deep systems chops — you reason naturally about memory, parallelism, and performance. Rust is a plus; strong C++/Go/systems experience that transfers is welcome.
- Serious data engineering experience — large-scale data processing, columnar formats, correctness/validation at scale, schema discipline.
- AI experience is optional — but the curiosity to go deep on it is not.
- Must already be in the US.
Perks
If you’re in SF/NY, there are offices, but if you choose, you can WFH. We have on-sites every few months to let the team mingle, at various locations! executive/career coaching if desired.
2. You really need advanced data engineering experience. AI experience is optional, though we may test you for aptitude.
3. I've mentioned a keyword in my HN profile — include it in your email (plenty of people just blast every address in these posts). I'll read every email mentioning that keyword sent in the next two days!
We are looking for candidates that are excited to join us on a mission to raise the standard of trust online. All of our roles are fully-remote, except where specific locations are noted. Compensation is transparent across the organization, and all team members within the same professional level and global region receive the same compensation.
Kadoa is the web data layer for finance. We use coding agents to build, monitor, and repair deterministic data pipelines for investment firms, so they can make faster and better decisions.
All founders have spent years in the trenches writing web scraping and ETL code and still do it almost every single day. We are growing fast, have a drama-free and distraction-light environment, and try to minimize the distance between the code & data you ship and the customers who use it.
We are looking for people who share our passion for software craftsmanship, data, and AI.
We're a lean remote team and are looking for low-ego generalists with high agency that can help us build a platform that combines the most intuitive UX with world-class accuracy and performance.
Blaine, WA | CaseLight Systems Inc. (CSI) | Solo Founder | Remote (US Only) | Founding Systems Engineer | FULL EQUITY (30% Stake)
Please Read First: Very specific skill set needed, non-negotiable.
I am a retired 25-year federal law enforcement and intelligence unit practitioner building CaseLight (CSI). CaseLight is an offline-first, secure Windows desktop application engineered to replace the chaotic, multi-app workflows used by 50,000+ independent private sector intelligence firms and rural police departments who are priced out of enterprise tech. By utilizing a local-first Tauri/Rust framework and an encrypted SQLite sandbox, CaseLight automates forensic data layout and locks down an unalterable digital chain of custody, completely bypassing cloud-hosting liabilities, third-party subpoena exposure, and infrastructure overhead.
Core Architecture Requirements: This is a low-level native systems role. We are explicitly filtering for senior developers with verified production experience in Tauri, Rust, SQLite/SQLCipher, and React.
Mandatory Specialized Capabilities:
- OS-Level Multi-Threading: Deep experience writing asynchronous background channels in Rust to process multi-gigabyte file payloads without blocking the UI main thread.
- Local Cryptography: Practical implementation of on-board SHA-256 hashing, metadata preservation, and runtime SQLCipher database encryption entirely on local client hardware.
- Memory Optimization: Expert understanding of the Rust borrow checker and native Windows execution constraints to ensure ultra-low RAM footprint sandboxing.
If your background is primarily in cloud-dependent web architectures, standard mobile apps, or if you represent an offshore agency, please pass on this listing so we can protect each other's time.
The Traction & Terms: Fully incorporated as a Delaware C-Corp (CaseLight Systems Inc.). Our multi-window desktop wireframe maps are complete and our comprehensive 12-section technical requirements specifications manual is 100% development-ready. This isn't an un-fleshed-out idea project; I have it all mapped out in black and white.
Active Seed Pipeline: Multiple applications are currently submitted and under review with regional angel networks and startup investors. We possess deep, active distribution roots across regional networks and secured 11 Letters of Intent from regional investigations firm principals within a brief 48-hour outreach loop.
Offering a 30% founding equity stake with standard 4-year vesting and a 1-year cliff. Marketing and capital re-investment belong entirely to me.
If you are a U.S.-based senior systems engineer passionate about data privacy, native desktop speed, and absolute local control, reach out directly to review the technical specification manual under a standard NDA.
Contact: Please reach out directly to me via email at charles@getcaselight.com

Distru (https://www.distru.com) | Senior Software Engineer | USA | REMOTE (Americas & Europe) | Full-Time
Distru is the #1 ERP in the cannabis industry, $3B in annual sales flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.
We're profitable, stable, and growing — no runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).
Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce — a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.

RedLine Solutions is hiring a fully remote mid-level C#/.NET developer. We are looking at an early September start date. I'm posting this way ahead of time to try something weird: If you are an interested developer, please do NOT contact me directly. Instead, find someone who will vouch for you and have them send me your resume`.
No, I'm not on some kind of power trip (yet). I just got my fill of automated application spam a long time ago; the tales I could tell. This is my modestly creative attempt to circumvent the AI's. Might be good practice for SkyNet, eh?
We are not looking for a know-it-all. Instead, we desire a "wants to learn it all". We're a small company, but our System Architect / Dev Lead is seriously a unicorn. If he mentors you for a year or two, your career is golden. Back in the day, I secretly believed I was one of the best around. Then I worked with Stephen. I've learned a ton from him, and I'm his boss.
We're a small, agile, creative and laid-back team who work hard but value work-life balance. I take great pains to make it so. If you're smart, work hard, and love writing software, ask a friend or former boss to vouch for you and have them send your resume`.

Mitty | First Engineer| Honolulu, HI or REMOTE | Full-time | Base + Founding equity
Hi I’m Devin.
Do you love hard problems? Do you find yourself thinking about new ideas on a daily basis? If so, you are the person I’m looking for!
Biz overview: Our phones camera rolls have 10,000+ photos and videos… most aren’t good but some are. Mitty analyzes the content, creates the idea from what exists, and edits the footage → presenting you with a finished video to post on social. Pretty neat huh! Well, that’s the idea. Also, hard to pull off, which is why I need you!
I'm the founder. You will be the first technical hire and own everything technical — pick the stack, make the architecture calls, write the code, and hopefully stay lead engineer for the life of the company. I’m technical but not good enough.
90-day goal: ship v1.
Helpful: ML/AI + video understanding / computer vision; mobile (iOS preferred); video processing/editing pipelines; comfort wiring up LLM + vision APIs (Anthropic, OpenAI, etc.) and can workout without micro mngmt.
What I’m trying to build: category leader in AI video creation around pre existing content (different than opus who is more podcast style), built toward an acquisition or Series B in ~3 years (Adobe, Canva, Meta, Google are the obvious acquirers).
Comp: $150k base (or more depending on skill) + performance bonus + founding-level equity scaled to experience.
Ps. I don’t expect you to be THE Expert at all of this. Just someone who is good to workout with and likes figuring things out.
Role + details: https://mitty.film/careers/first-engineer.html
Apply: email Devin@PineappleHi.com — a note plus anything relevant (resume, GitHub, things you've shipped).

Quantum Rise | Chicago or NYC (preferred), Remote for the right candidate | Full-time | No visa sponsorship | https://www.quantumrise.com/
Quantum Rise is an AI-forward consulting startup serving the mid-market in the US. We see companies in multiple industries struggling to understand how to leverage artificial intelligence in their day-to-day operations, trying to understand what their existing workforce now needs to know, or trying to understand whether they're about to be disrupted and need to change how their existing processes work. Many have business problems which "traditional" machine learning could help with even prior to the current GenAI hype cycle, but for whatever reason hadn't prioritized doing until now. Many have employees looking to incorporate agentic AI safely and effectively across different business areas. We try and help getting a handle around these issues and designing outcome-driven solutions.
Agentic AI Solutions Manager: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply embedded in agentic engineering practice across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners and need help navigating a new, powerful scary world.
AI Solutions Engineer: You're someone who has experience across the entire spectrum of applied automation, machine learning and agentic engineering.
We think of these two roles as complementary -- agentic AI solutioners help clients understand the forefront, whereas pure AI solutioners help them pick the right solution not the one they saw in the news.
Both are front-facing development roles for someone who loves both tech and tackling real business problems. We love people with prior experience in multiple industries.
To apply, send me an email at julian.berman at quantumrise.com, mentioning HN and including your CV.

SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers
SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.
Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.
We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.
In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.
We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~550). Now we’re scaling the platform.

Axle Health (health tech x logistics) | Backend, Interoperability, and DevOps roles | ONSITE: Santa Monica (5 days) | https://www.axlehealth.com/careers
Home-based care should be the default in American healthcare. It isn't, mostly because the technology has never been good enough. Patients heal faster at home, it costs a fraction of facility-based care, and it's what people actually want — yet the industry runs on phone calls, spreadsheets, and systems built in the 90s. We started Axle Health because we think that's fixable, and because the stakes are high enough that it's worth doing right.
We're Axle Health, and we think in-home care deserves world-class technology. We're building the operating system for home-based healthcare — the scheduling intelligence, the clinician tools, the logistics coordination — everything that has to work perfectly so a clinician shows up at the right door at the right time with everything they need. It's a hard and important problem, and we're just getting started.
The complexity is real: real-time scheduling optimization across dynamic clinician networks, last-mile logistics that make Uber Dispatch look simple, integrations with every flavor of EMR and payer system you've never heard of, mobile-first tools that have to work in spotty cell coverage in someone's living room, and the compliance surface area that comes with handling PHI at scale — we need to build it all, and we want people who think this stuff is genuinely fun.
Currently hiring Senior Software Engineers (7+ YOE) for:
Backend (Python + Django): https://www.axlehealth.com/careers?ashby_jid=8db08b55-399c-4...
Interoperability (Typescript + Node): https://www.axlehealth.com/careers?ashby_jid=0bcdc195-ac3f-4...

Ecosmic | Senior DevOps Engineer | Remote (Italy) | €50,000–€60,000
Ecosmic is on a mission to reduce threat exposure in space by building software for Space Situational Awareness. To achieve this, we built a team of flight dynamics engineers and computer scientists to build & package in-house algorithms into easy-to-use, reliable, and secure products. As an example, our platform recently allowed us to identify a series of close approaches in GEO involving Russia's Luch/Olymp-2 and a Western telecommunications satellite, possibly attributed to SIGINT activity.
We're hiring a Senior DevOps Engineer (strong mid-level candidates are welcome too!) to aid the effort of unlocking on-premises deployments of our algorithms with Kubernetes, and to contribute to the evolution of our platform.
Our stack includes Python for backend services and high-level algorithm tooling, C++ for performance-critical components, AWS for cloud infrastructure, and Terraform for IaC. We currently use managed serverless services, and we’re beginning a gradual migration from C++ to Rust for its reliability guarantees.
You’d join a team of three software engineers who love working in such a fantastic domain. I currently take care of most of the infrastructure work with the team, and we’re looking for someone who can help us tackle this new challenge.

Hey HN! Air Space Intelligence (https://www.airspace-intelligence.com) is hiring in Boston. We're a frontier AI and product company for critical industries and defense, backed by a16z.
Last week, the FAA awarded us a 12-year, $875M contract to build FMDS and SMART - the flow-management and airspace optimization systems that will become the technological backbone of the FAA's Air Traffic Control. What we ship in the next two years will define how this country moves through the sky for the next fifty.
At the core is one of the largest real-time optimization problems in the world: how do you safely sequence ~40,000 flights/day while routing around weather, military airspace, equipment outages, and constant real-world churn? The system has to be right every time, and reliable at scale.
More here: https://www.faa.gov/newsroom/modern-skies-trumps-transportat...

fractile.ai - AI hardware, backed by Founders Fund - London (UK) - Onsite
ABOUT FRACTILE Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the amount of time they take to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts.
We’ve recently raised $220M from Founders Fund and Accel and the most important work lies ahead. Come and join the mission!
THE ROLE As a Software Engineer you will be a core part of our technical team working alongside the hardware, software and research teams to solve cutting-edge problems in AI hardware, ranging from verification to simulation, alongside the best of the best (DeepMind, Apple, Meta…).
ABOUT YOU 1) You have exceptional ability. We look for pivotal IC contributions that solved the hardest problems in big tech companies or hedge funds; competitive hackathons, International Olympiad medals, or rank highly in other competitions like advent of code
2. You are a top engineer. We are not looking for specific languages or technologies - you will be a master of several, you excel at algorithmic skills and solving problems logically in any programming language. And you are very comfortable learning new skills on the fly. You like to work in Python and C++
3. It’s likely you have several years of professional experience, but we will make exceptions for the right candidate
4. You want to work with the best. And you are excited to work in chips, solving the hardest problems at the frontier of AI
WHAT WE OFFER 1. Competitive compensation and meaningful equity 2. A very cool office with London's best views 3. Private medical insurance and pension benefits

Munich, Germany | Remote (CET, overlaps US mornings) | Freelance / contract only, not seeking employment
20+ years across product, UX and frontend, now doing user-facing AI engineering.
What I do best right now: you shipped an app fast with Lovable / v0 / Cursor and it works, but it looks and behaves like the AI default. I take that codebase and make it actually usable and on-brand. Real design system in code (not a Figma file nobody maintains), consistent components, the polish and interaction layer that makes it feel like a product instead of a prototype. Done-for-you, in your repo.
I also help teams that already build with AI but get inconsistent, off-brand results, via a hands-on workshop / masterclass, so your people can produce in your own style instead of getting generic output.
Tech: React/Next.js, TypeScript, Tailwind, design systems / design tokens, Figma, Claude Code + agentic workflows.

Kinelo | kinelo.com | San Francisco | Onsite (with a bit of flexibility)
Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.
We're hiring for two roles right now:
- Product Engineer / Senior Software Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market?
- Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast.
Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).
Please email us at jobs@kinelo.com.
If you want to stand out:
- For the product engineer role, tell us how you think the job of a software engineer is changing.
- For the GTM role, tell us about a time you got massive results with limited resources, all through your ingenuity, creativity, and hard work.

Credo Health | Full Stack Engineer | NYC (HYBRID — 1 day/week onsite, otherwise remote) | $125k–$175k + equity | Full-time
I'm Ketan, Head of Engineering at Credo. We're a seed-stage, HIPAA-compliant health-tech company fixing one of healthcare's dumbest problems: getting the right patient data to the people who need it. Billions of pages of medical records still move by fax every year — causing care delays, admin overload, and dangerous gaps in what providers know. Our AI platform gets clinicians the patient answers they need fast. We have paying customers using it daily.
This is an early engineering hire on our Platform team (5–7 people), reporting to me. You'll work the full stack, shape our architecture, and ship to real users every week. High ownership, lots of surface area, frequent collaboration with our ML team.
Stack: Python/Django, Postgres, Vue, Temporal (for our patient-ingestion pipeline and long-running workflows), Google Cloud, and a mix of AI models (mostly Gemini + OpenAI). No prior Temporal experience needed, just enthusiasm for it.
How we work: strong code-review and pairing culture, serious about testing, async-first with a single daily sync, and we've fully integrated plan/spec-based AI tooling into our workflow (Claude, Cursor, CodeRabbit, Copilot — your choice).
Looking for 3–5+ yrs full-stack experience, solid Python + a backend framework, comfort with relational DBs, a modern JS framework, real testing chops, and someone who thrives with ambiguity and owns problems end to end. Healthcare/FHIR/HL7 and AI-feature experience are nice-to-haves, not requirements. Must be in/near NYC for the weekly in-person day.
Apply here: https://app.dover.com/apply/Credo%20Health/0cc80a85-2953-40c...
Happy to answer questions in the thread!

Komodo Health | Full-Time | $200–298k + equity | SF/NY (a few days a month) or Remote US | Can sponsor/transfer
Healthcare in the U.S. is a mess. Komodo Health is fixing that—with data. We've mapped the patient journey across the country to build the most complete picture of disease burden and treatment gaps. Our customers are pharma, payers, and health systems who actually want to do something meaningful with that information.
We have an exciting project, where we are building a custom, healthcare data specific compute engine that can be orders of magnitude faster than any analytics solution out there.
We're looking for a Staff-level Data Software Engineer (emphasizing the importance of both data and software here!) to work on this project at the core of our platform. This is a data-engineering problem solved with real software-engineering rigor: you'll be designing the data structures and query systems that make analytics over massive healthcare datasets feel instant. Not wiring up someone else's pipeline DAGs — building the engine underneath.
It's demanding, low-level, performance-obsessed work, and correctness is sacred. If you care about where the microseconds go and refuse to trade off getting the answer right, you'll fit in.
The team is very small, and we intend to keep it this way. If you are interested in heads down work with a group of high caliber like-minded folks, this may be perfect.
What we're looking for
- Staff-level software engineer with deep systems chops — you reason naturally about memory, parallelism, and performance. Rust is a plus; strong C++/Go/systems experience that transfers is welcome.
- Serious data engineering experience — large-scale data processing, columnar formats, correctness/validation at scale, schema discipline.
- AI experience is optional — but the curiosity to go deep on it is not.
- Must already be in the US.
Perks
If you’re in SF/NY, there are offices, but if you choose, you can WFH. We have on-sites every few months to let the team mingle, at various locations! executive/career coaching if desired.
Before you email
Interested? Email me: ramraj.velmurugan@komodohealth.com.
1. You need to already be in the US.
2. You really need advanced data engineering experience. AI experience is optional, though we may test you for aptitude.
3. I've mentioned a keyword in my HN profile — include it in your email (plenty of people just blast every address in these posts). I'll read every email mentioning that keyword sent in the next two days!

Blaine, WA | CaseLight Systems Inc. (CSI) | Solo Founder | Remote (US Only) | Founding Systems Engineer | FULL EQUITY (30% Stake)
Please Read First: Very specific skill set needed, non-negotiable.
I am a retired 25-year federal law enforcement and intelligence unit practitioner building CaseLight (CSI). CaseLight is an offline-first, secure Windows desktop application engineered to replace the chaotic, multi-app workflows used by 50,000+ independent private sector intelligence firms and rural police departments who are priced out of enterprise tech. By utilizing a local-first Tauri/Rust framework and an encrypted SQLite sandbox, CaseLight automates forensic data layout and locks down an unalterable digital chain of custody, completely bypassing cloud-hosting liabilities, third-party subpoena exposure, and infrastructure overhead.
Core Architecture Requirements: This is a low-level native systems role. We are explicitly filtering for senior developers with verified production experience in Tauri, Rust, SQLite/SQLCipher, and React.
Mandatory Specialized Capabilities: - OS-Level Multi-Threading: Deep experience writing asynchronous background channels in Rust to process multi-gigabyte file payloads without blocking the UI main thread. - Local Cryptography: Practical implementation of on-board SHA-256 hashing, metadata preservation, and runtime SQLCipher database encryption entirely on local client hardware. - Memory Optimization: Expert understanding of the Rust borrow checker and native Windows execution constraints to ensure ultra-low RAM footprint sandboxing.
If your background is primarily in cloud-dependent web architectures, standard mobile apps, or if you represent an offshore agency, please pass on this listing so we can protect each other's time.

DV Scibids is the AI-powered digital campaign activation arm of DoubleVerify — the market standard for digital media measurement trusted by hundreds of Fortune 500 brands. Our Data Engineering team owns the critical integrations and data flows that connect Scibids' optimization engine to the broader adtech ecosystem.
In this role you will own and build backend services and data pipelines that power product expansion — exploring external partner APIs, designing reliable ingestion and reconciliation layers, exposing internal endpoints for other DV teams, and keeping production systems observable and performant at scale.
Stack: Python, SQL, BigQuery, Cloud SQL, Cloud Datastore, Cloud Run (GCP), Prefect, Docker, CI/CD, Git. Java or Rust a plus.
Looking for: 3+ years in data engineering or backend engineering. Strong Python and SQL. Experience integrating with external APIs and operating production data systems at scale. Comfort with cloud-native environments and modern engineering practices. AdTech/auction-system familiarity is a plus, not required.

89k for sr data engineer in nyc onsite? thats really depressing if this is what the job market is like .

That's lower than a good barber in NYC
This isn’t a job board for high-paying SE jobs. It’s for people who want to gamble on joining early-stage startups.
This posting is for a >15 year old publicly traded company on the NYSE. I wouldn't consider that an early-stage startup.
