• 3+ years building software professionally
• You have demonstrated experience taking fuzzy ambiguous problems and turning them into working shipped features independently
• Comfortable jumping between languages and parts of the stack. We don't expect you to know OCaml on day one, but we do expect you to be the kind of person who'd be excited to pick it up
• You have strong opinions about code, held loosely. You should want to leave the codebase better than you found it while balancing engineering momentum
• You like working in-person with a small team where the line between product and engineering is blurry
• Experience or interest in domain specific languages, language design, and projectional editors
• Background in the life sciences, lab automation, or software work in any domain where the user is an expert in something you're not.
• Experience with OCaml, or with other ML-family languages (Haskell, F#, Rust's type system, etc.)
• Experience with Next.js, Tailwind, FastAPI, NeonDB, & Zustand
• Experience or interest in compilers, interpreters, heuristic algorithms and optimizing systems, especially unconventional and domain specific tools
• Familiarity with LLM-in-the-loop systems: parsing, structured extraction, evals
• Startup or small-team experience, especially earlier stage.
• Location: San Francisco, in-person at our office in SoMa.
• Compensation: $140K – $180K · Offers Equity
• Process: intro call → take-home project → follow up technical conversation → onsite technical interview → offer.
