Anvil | Various Roles | Greater Boston | HYBRID | Full-time | $140k-$180k + 0.5-2.5% equity

Anvil | Various Roles | Greater Boston | HYBRID | Full-time | $140k-$180k + 0.5-2.5% equity We're a seed stage (VC backend) company building a vertically integrated design and manufacturing platform for precision mechanical parts. We are developing our own CAD/CAM software running on top of our own manufacturing facility. The team has previously developed CAD kernels, design software, and autonomous robotic manipulators, and comes from Amazon Robotics, Siemens, nTop, and Vicarious Surgical. Most design and manufacturing software companies treat the factory as a black box and optimize geometry in isolation. Our bet is that the only way to really bring software and ML into design and manufacturing is to own the full process ourselves. The platform you'd help build includes: customer-facing design software, the ML engine that turns CAD files into machine instructions (G-code), the simulation layer, and the shop floor operations themselves. We are looking for someone independently driven who wants to operate like a founder. You'd own architecture, help shape the company's vision, and build a product from the ground up. If you've worked on cloud infrastructure, distributed systems, CAD/CAM software dev, geometry kernels, robotic perception, motion control, or spent time on a shop floor, we'd like to talk. We are open to sponsoring visas for the right candidate. Roles: Founding Computational Geometry Engineer: Hybrid B-rep + SDF kernel work. STEP AP242 ingestion, B-rep surgery, feature recognition, and the geometry layer underneath our DFM and CAM pipelines. If you've worked on Parasolid, OCCT, nTop, or shipped anything that touches BRep diff, parametric replay, or differentiable geometry, we want to talk. C++ and Python. Founding Full-Stack Engineer: Someone who can take ownership of the reliability, automation, and evolution of our core systems that tie into our CAD/CAM software, internal shop-floor systems. You’ll work across the stack, with a strong emphasis on backend, infrastructure, and system-level engineering, to strengthen the foundations that everything else runs on. This role is for someone who enjoys digging into complex systems, building the architecture and tooling to keep them running reliably (including the frontend).

MiLaboratories | Senior Software Engineer (Biologic Discovery) | Bilbao, Spain | ONSITE | VISA | RELOCATION

MiLaboratories | Senior Software Engineer (Biologic Discovery) | Bilbao, Spain | ONSITE | VISA | RELOCATION MiXCR is the standard for immune analysis, cited in thousands of papers. Platforma is the OS on top — bioinformatics as self-serve, interoperable "blocks" for biologic discovery. 5 of the top 10 pharma (Moderna, Pfizer, others) run discovery with Platforma today. Goal: 10 of 10 by year-end. Hiring 4–5 engineers in 90 days. Our tools are in the methods of approved cancer immunotherapies and COVID vaccines reaching millions. The next paper citing us could be the next drug. We merged frontend, bioinformatics, and data into one team. AI killed the silo wall. Bioinformaticians who leaned into engineering and engineers who leaned into biology now ship at multiples. WHAT YOU'D BUILD - Discovery pipelines: raw sequences → pre-IND leads. Antibodies, biomarkers, workflows real scientists use. - The SDK for comp scientists: TypeScript, Tengo (a Lua-like workflow DSL — yes, you'll learn it), Rust. - The data layer: thousands of formats reduced to one. PFrames, Parquet, DataFusion, lazy columnar everything. WHAT WE'RE LOOKING FOR - Strong TS in 100k-line monorepos (pnpm, Turbo). Polars > pandas. Node ≥22. - Bioinformatics exposure or appetite to learn it month one. We can teach VDJ recombination; not curiosity. - Tolerance for sparse docs and niche DSLs. "Fix the SDK, don't work around it." OFFER - €90–120k base, real ESOP, ARR-tied bonus — when we grow, you grow, in cash, this year. - Bizkaia Special Impatriate Regime: ~15–20% effective tax. Beats London / Berlin / Amsterdam net. - Visa, relocation, soft-landing. No HR, no take-homes. Direct line to engineering. - Bilbao: ocean, mountains, Michelin, low cost of living, highest quality of life. Onsite — context-sharing needs same room. Email: stanp@milaboratories.com (CEO). Subject "HN", include GitHub. I reply personally. Tell me about a scientific CLI you wrapped, a plugin SDK you built, or a Polars query that survived 50M rows.

We are building the "OS for Biology"—the foundational infrastructure where all biological data is transformed into life-saving breakthroughs. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + deep biological nuances) requires high-bandwidth, in-person collaboration. We dissolved traditional departmental silos. We are hiring hardcore builders, not analysts, for a critical core role: *Senior TypeScript (SDK & Platform):* You will architect our frictionless, AI-native SDK to scale our ecosystem. This is not a CRUD web dashboard. You will build a heavy local desktop application that bridges directly with a high-performance Rust data layer.

You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions - up to 50% in total). * The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin. * Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have." * Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search). * Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.

We are looking for people deeply passionate about AI research. I am steering our work culture towards "live-to-work": If you wouldn't be doing AI research working somewhere else, then it is not a good fit.

Tufalabs is an independent AI research lab in Zurich, focused on high-impact academic-style AI research and large-scale LLM development.

The ultimate goal is automating AI research, with a strong focus on alignment and safety in the limit. We can only sponsor visas for people with EU nationality. The position is onsite, fulltime. We are self-funded, from what i call "self-propelled machine learning": I applied ML to cool domains and made returns that way. I can give more details about this privately.

Di Rezze Family Office | AI-Native Technical Operations Lead | Miami, FL (ONSITE) | $130K-$200K + Early Equity | Full-Time We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now. We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance. Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework. What we're looking for: 3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas. What you get: Meaningful early-stage equity (not a token option grant) Direct access to founders and decision-makers, no layers A say in the technical architecture from day one Relocation to Miami fully covered Health, dental, vision Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.
