Proton builds the privacy-first alternative to Big Tech: Mail, VPN, Drive, Pass, Calendar, and Lumo AI. We're profitable, have no VC control, and are majority owned by the nonprofit Proton Foundation, so no one can force a change in mission.
The Drive Foundation team builds the core SDK powering every Proton Drive client,C#, TypeScript, and Rust daily, with Swift and Kotlin bindings for mobile. It's foundational work: what you build here ships to every Drive client, and there's a crypto model revamp plus a Rust based next gen SDK on the roadmap.
Looking for someone with 5+ years of professional software experience and strong Rust expertise (ownership, concurrency), plus experience building libraries for client applications (web/mobile/desktop). Don't check every box but think you'd be a strong fit? We say apply anyway.

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.
Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.
Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.
Comp & apply
- Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

MWI Animal Health is a leading U.S. distributor of animal health products, medications, and technology solutions for veterinarians and livestock producers.
1. Senior Application Developer (React + Composable Commerce)
We're hiring a senior dev (8+ yrs) to lead projects, mentor juniors, and build scalable apps end-to-end. Stack: React (Redux/Context), C#/.NET, microservices, headless commerce (CommerceTools, ContentStack), NoSQL + relational DBs, event streaming, TDD. You'll turn messy business requirements into solid technical solutions and help shape our architecture. Bonus: WMS experience. Apply if you like leading, mentoring, and shipping.
2. QA Engineer
We're hiring a QA Engineer to own quality across our suite of connected web applications and the shared services between them. You'll mix hands-on manual/exploratory testing with building and maintaining automated suites (end-to-end, integration, component), with a big focus on the seams between apps: navigation, shared auth, data hand-offs, and micro-frontend integrations. You'll own the full bug lifecycle, wire tests into CI/CD as reliable quality gates, and partner with product and engineering to build testability in from the start.
Ideal fit: 3+ years in QA testing web apps, across both manual and automated testing with modern frameworks (Playwright, Selenium) and unit/component tooling (Jest, Vitest). Comfortable testing SPAs and REST APIs, with enough JavaScript/TypeScript to write and debug test code. Bonus points for React, Vite, monorepos, micro-frontends, GitHub Actions. Above all, a user-focused mindset — catching problems before customers do.
3. Senior DevOps Engineer
We're hiring a Senior DevOps Engineer to standardize application deployments, containerization, and release processes across our org. You'll build shared CI/CD pipelines, containerize apps with Docker/Kubernetes, and create the tooling and golden paths that let teams ship reliably. Ideal fit: solid experience with CI/CD (GitHub Actions/GitLab CI/Jenkins), IaC (Terraform/Helm), and cloud providers (AWS/Azure), plus a track record of driving standardization at scale. Pragmatic, collaborative, and motivated by making other teams more productive.

Rangeview is building the foundry system that reindustrializes America. We apply advanced software, deep automation, and materials science to making metal parts. You'd be an early engineer on FactoryOS, the application that runs our factory: production workflows, equipment telemetry, part tracking, and quality traceability.
High-ownership generalist role covering operator-facing frontends, backend services, and integrations with real machines on the floor. Stack: TypeScript/React, C#/ASP.NET, relational databases. MES/ERP, IoT, or manufacturing/aerospace/defense experience is a plus.
2+ years shipping production web apps. ITAR: must be a U.S. person. Hiring Level 1 or 2.

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.

Clinical software is where a provider's time goes to die. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.
Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. We're building a foundation designed to eventually scale across thousands of providers and multiple medical specialties.
You’ll join as a founding engineer working directly with myself (Xoogler SWE) and my co-founder (one of the US's best known O&P clinicians), and a new engineer. You will own massive surfaces end-to-end, making the foundational architectural decisions for our entire platform. We have clinics using our suite and already saving hours a day, but we've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine.
- The Stack: C#/.NET, contract-first gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.
- How we work: We have total flexibility on your workflow. Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.
- Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.
To apply, email me directly at jlyman@axoventures.co with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line!
1. Please make sure your contact information is on your resume`!
2. We need a developer located within three hours of Pacific timezone.
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 with or without AI. 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`.
