Hey this is Brian from Gain Compliance, we've had success hiring out of a hacker news thread before, so let's give it a spin again.
We are a small company that builds financial reporting tools for the insurance industry. While the domain might be foreign to most, we are having a lot of fun building modern web software with React, Python and Node running on GCP infrastructure. You'll be joining 7 other engineers split into two full stack product focused teams.
We've been around over 10 years, are profitable, and value empowering our customers to breeze through their boring compliance tasks, building great teams that focus on outcomes over features, and work place stability.
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.
OpenVPN Inc. | AI Platform Engineer | REMOTE | Full-time | $140,000 - $150,000 per year
Come work at OpenVPN! Yes, THE OpenVPN!
You'll own everything from developer tooling and internal AI workflows to cloud infrastructure and governance-defining standards, security, and cost controls from scratch.
If you want to build the AI layer for a real company (not just models, but the systems around them), this is a high-ownership position shaping how AI gets deployed, used, and scaled across the org.
We want to use AI to improve productivity and efficiency and make our employees even better. This role will shape the future of the company.
Project Debug raises, sorts by sex, and releases millions of (non-biting) male mosquitoes in Singapore to reduce the local mosquito population and prevent the spread of dengue and other mosquito-borne illnesses. Our trial in Fresno, CA showed a 95% reduction in female mosquitoes during the seasonal peak.
Our engineering team is pretty small and we need a solid generalist engineer who is interested in becoming a domain expert in our factory, where we do automated rearing and sex sorting. If you run a homelab, have tinkered with Arduino, and can prompt/write some Python, we can teach you everything you need to know about our stack (Go, Python, React, Kubernetes, Tensorflow).

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.
Email steven@kanary.com with something you've built and why it was hard.

We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.
We’re building out our team in the following areas:
We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.
We are looking for a senior engineer with at least ten years of full stack experience, a strong focus on product and UX, and optionally some experience building LLM based products. Currently we are focussed on building tooling that enables us to capture domain knowledge from experts to streamline prompt creation and evaluation.
Our tech stack is Typescript, React, Next.js and Tailwind. On the backend we use Drizzle with Neon, deployed and monitored via Vercel. Please note that we are working in the CET timezone.
We have pre-seed funding from a major US VC and are experienced founders. You’ll be working alongside the founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and will have a chance to shape the company, product and of course the engineering culture.

Moyai is an AI-powered agent monitoring tool for AI engineers looking to catch agent failures in production. Reach out to the founder directly: https://www.linkedin.com/in/rhommes/ or visit our website https://moyai.ai
We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.
If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.
Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.
- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.
- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.
You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.
Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.
Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.
Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.
Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.

Conductor lets you run a team of coding agents on your Mac. We've grown 10x since January, and just recently announced our $22m Series A. We're a small team looking for exceptional software engineers and designers.
Burnin (London or NYC) | Founding Research Scientist + Founding Engineering Lead | Hybrid (Some on-site) | Full-time
We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed.
Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed.
Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python.
Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS.
Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.

(Applicants must be authorized to work in the United States. UpMetrics is unable to sponsor or take over sponsorship of employment visas at this time.)
INDATA | AI Development Associate | REMOTE (US) or San Diego | FULL-TIME | $95,000–$115,000
We're hiring a junior dev who is genuinely AI-native — your primary tool is Claude Code or Cursor, not your own typing. You'll extend our agentic AI copilot embedded in Architect AI, our portfolio-management web app: text-to-SQL over financial schemas (holdings, transactions, performance), RAG over our internal docs, action tools, deploy and operate the system on Linux + Docker.
Required: real SQL chops, ability to read Python and judge AI-generated code, a public project we can look at where you actually used Claude Code / Cursor / Copilot to ship something. 0–2 years professional experience. Recent grads welcome. You'll report directly to the Director of PM who built the system.
We're building a new computing stack with formally verified data, memory, and resource isolation between executions for instant, truly elastic global compute. This includes designing and building a production language in a way that's never been done before, with complete, mechanized formal specifications and a certifying compiler from the start. Our immediate goals include an alternative to eBPF and building the world's first serverless networking infrastructure.
We are VC funded with runway for multiple years. The team is composed of PhDs from Stanford, UW, OSU, and Brown, advised by professors from MIT and UWaterloo.
We are currently hiring for the following positions:

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We just recently announced our $42M Series B! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
This year, we’re growing our engineering team from 25 to 40. We’re looking for product-minded engineers to join us as we continue to scale! We’re looking for someone who thrives on ownership, drives results, and cares deeply about both technical excellence and customer impact.
We’re hiring various mid-level, senior-level and staff-level engineers. See some of our openings below:
* In the form, be sure to mention that you heard about this opportunity via Hacker News.

Gain Compliance | Sr Software Engineer | Remote (USA) | Full-time | ~$160k | https://join.gaincompliance.com
Hey this is Brian from Gain Compliance, we've had success hiring out of a hacker news thread before, so let's give it a spin again.
We are a small company that builds financial reporting tools for the insurance industry. While the domain might be foreign to most, we are having a lot of fun building modern web software with React, Python and Node running on GCP infrastructure. You'll be joining 7 other engineers split into two full stack product focused teams.
We've been around over 10 years, are profitable, and value empowering our customers to breeze through their boring compliance tasks, building great teams that focus on outcomes over features, and work place stability.
We wrote a lot more over at https://join.gaincompliance.com if you are interested.
SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Kanary | Full Stack Engineer | Remote (US) | Competitive Salary + Equity | Python / React
Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space
We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.
We’re building out our team in the following areas:
* Product Software Engineering (Quantitative Modeling)
* Program Synthesis Engineering
* Applied Category Theory Research
* Bayesian Software Engineering
* Finance Operations (Accounting, Analytics & Workforce)
We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

If you want to build fast with high autonomy and believe in strong typing as much as we do, we'd love to hear from you!
Hi! We're Ontix. We're building the business layer to connect siloed datasets and query them with natural language, offering insights to SMBs they couldn't get before. We're fully funded by our sibling company, and are looking for remote freelancers in the US and full-time, onsite employees in San Diego, California (if you're into that kind of thing). We're looking for experience in the following roles:
+ QA: We're looking for a QA engineer deeply familiar with the software lifecycle in the age of agentic coding. You'd have a lot of responsibility, but also the opportunity to define what solid QA looks like at Ontix.
+ Azure Cloud Engineer: We're a mostly-AWS shop, but we have a few potential customers that are deeply entrenched in the Azure ecosystem, including a migration from SharePoint to Fabric + OneLake. You'd be leading the charge on that.
+ Infosec + Automated Vulnerability Scanning: If you browse new CVEs over breakfast, we want to talk to you. There's a huge demand among our current customers for continuous vulnerability scanning, both in the codebase and on the deployed edge. We have some test platforms, but would love a more robust solution we can market.
+ Full-Stack WordPress Developer: Our sister company is a bit old school still: If you can parachute in to a PHP + Vue 2/3 + WordPress + AWS EC2 environment, we would love to pass on your number to them.
We're looking to grow quickly as our client base expands. Healthcare, vision, and 401(k) for FTEs. If you're interested in any of these roles, or would like more information in general about us, please visit https://ontix.io or email l33t@ontix.io with a few sentences describing your experience, interest, and where you're located.
Normcore.io | Head of Strategic Finance | Full-time | $100-140K USD | Remote PT/ET Hours
I'm the founder of Normcore.io, an autoscaling game server hosting service and Unity plugin that includes all of the pieces you need to create a multiplayer game. We launched a few years ago and have hosted over 1 billion multiplayer games since launch. We also make our own VR titles that are built on top of our own networking tech: https://www.youtube.com/watch?v=djsPTbs7R_w
I'm looking to hire a Head of Strategic Finance. We're looking for someone to model our revenue streams, create financial projections for the company, and help design the monetization strategy for our titles. We make heavy use of Claude for Excel and Claude Code to create tools to track popular titles, store charts, basically any data we can use to understand the gaming market. We then use that data to determine the direction for the company.
Reasons you'd love working with us:
* Work with a small, focused, and extremely talented team.
* Fully remote job with flexible working hours and vacation (Our whole team is remote too)
* High work satisfaction, own entire features, and work on an SDK that’s already used by 100,000+ developers.
If you're interested, please send an email to careers@normalvr.com with your LinkedIn and a few sentences about why you would be a good fit for the role. Blank emails with resumés or generic applications that don't follow these instructions will be ignored.
Fastly | Software Engineers (Senior, Staff, Principal) | REMOTE (US, UK, EU) or ONSITE | Full-time
When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a globally edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design. We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services.
* Apply: https://www.fastly.com/about/careers
QUIC, but TCP experience and not UDP? Sorry, being a little pedantic but it's a real question.
Aqora | Paris, France / US / Remote (EU) | Multiple roles | https://aqora.io
Aqora is the "Hugging Face for quantum computing". We host datasets, benchmarks, and use-case challenges, plus the orchestration layer to run quantum algorithms and workflows across hardware backends, so results are reproducible, comparable, and actually move the field forward. We grew out of the QuantX hackathons at École Polytechnique and now run competitions and a public datasets hub for partners across pharma, finance, energy, and defense.
We're hiring:
* Senior Full Stack Software Engineer (Rust/React). Build the platform end to end: datasets hub, challenges, leaderboards, and the workflow engine that orchestrates quantum jobs across backends. You own features from schema to UI and care about developer experience. Bonus: data, ML, or research-platform experience.
* Quantum Computing Expert. Design challenges, curate datasets, define benchmarks, and shape how algorithms and workflows run on the platform. Work directly with enterprise partners to translate their problems into something the community can solve. PhD or equivalent depth in quantum algorithms, QML, or optimization.
* Chief Commercial Officer, US. Own US go-to-market end to end: strategy, enterprise pipeline, team build-out. You've scaled commercial functions at a deep-tech, dev-tools, or research-platform company. Based in the US.
* Head of Marketing. Positioning, demand gen, and brand for a category still being defined. B2B technical marketing background required; quantum experience welcome but not necessary, curiosity is.
* Product Manager. Drive the roadmap across the datasets hub, challenges platform, benchmarks, and workflow orchestration. Strong technical instincts and experience shipping developer or research-facing products.
* Sales, EU. Enterprise sales into R&D and innovation teams across Europe. Long, technical sales cycles, consultative selling, comfort talking to PhDs and procurement on the same day. EU-based, remote.
Reach out to jannes[at]aqora.io with a short note on why this problem space and what you've built or sold before.

• Cloud native & freedom to shape our tech stack (TypeScript + Python)
Ideal candidate:
• Previous experience at start-up building tech at scale

Loophole Labs | Senior Systems Engineer | REMOTE (Americas & Europe) | $150k–195k USD + equity | Go, Zig, Rust, C, eBPF, CRIU, Kubernetes
We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.
If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.
Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.
What you'd work on:
- Hibernation surface: containerd shims and CRUISE, our Zig-native CRIU replacement.
- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.
- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.
You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.
Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.
Apply: https://loopholelabs.io/careers - we respond within the week (typically a few days).
Fortech Engineering | Full Stack Software Engineer | Primarily remote (Waterloo region, Canada) | $140-170K CAD + performance pay + earned equity
Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.
Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.
Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.
Stack: TypeScript, React, Tailwind, shadcn/ui, AG Grid, TanStack Query, Drizzle, PostgreSQL, Python (FastAPI), Node.js, Docker.
Looking for: full-stack, agentic-first as a daily working mode, shipper not writer.

Burnin (London or NYC) | Founding Research Scientist + Founding Engineering Lead | Hybrid (Some on-site) | Full-time
We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed.
Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed.
Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python.
Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS.
Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.

SonarMD | Senior Full Stack Engineer | Remote (US East/Central) | $180-220k+ | Unlimited PTO, healthcare, 5% bonus, 401k match
Healthcare AI company. We monitor IBD patients between doctor visits and catch clinical deterioration before it becomes an ER visit. Real patients, real outcomes, peer-reviewed studies.
Node/Express, React/React Native, Python, MongoDB Atlas, Postgres, AWS (EC2, Ansible, the real stuff, not just Lambda bingo). HIPAA/SOC2. Team of 5. Lots of data. More AI and ML in prod every other week. You will contribute to 5 and 6 figure mistakes and also the 6 and 7 figure outcomes. It's just another day in the life. You will discover your gaps quickly and then you get to close them. You will have real access and real responsibility. Your decisions will have meaningful impact on other people's lives. Some people struggle with that. You can't. You will own things. You will learn things. We will build things.
I am six interviews deep into candidates reading me AWS product pages after being asked about their approach to enrichment. If you have ever debugged something in production and have an opinion about literally anything, please talk to me. If you're interested: resume to eng.hiring@sonarmd.com.
If you're really interested: send a cover letter in .md format (no AI, I will know) with answers to: - Last 3 things you personally shipped to prod, preferably ones that failed or had unexpected results - Most recent thing you learned but are too embarrassed to admit you didn't already know - Your 3 biggest pain points working with AI/LLMs/agents - Most recent thing you built that you're legitimately proud of - Preferred tech stack - How many full, 8-hour-day, 5-day-a-week production shipping years you got under your belt, for real
The .md skips the line. I'll read it before anything else in the inbox.

Shepherd | ONSITE | San Francisco, CA
At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We just recently announced our $42M Series B! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
