What you will do
- Design and implement end-to-end features using a modern TypeScript monorepo, tRPC, and Inngest, ensuring high standards for reliability in a regulated environment.

Who this is a fit for
- Demonstrates deep full-stack experience in TypeScript, React, and Node.js, with a track record of owning complex features from ideation to production at early-stage startups.
- Possesses “Startup DNA”—you are comfortable with ambiguity, move fast without sacrificing quality, and have a relentless drive for self-improvement and technical excellence.
- Shows proficiency in modern AI tooling and an interest in bridging the gap between machine learning research and building production-ready, agentic systems.
Why this role is remarkable
- Join as a core member of an elite, small team of senior generalists where there are no PMs, giving you direct influence over every product and architectural decision.
- Work at the cutting edge of AI, building agentic systems and LLM-powered workflows that handle real-world, regulated legal processes rather than just simple chat interfaces.
- Backed by Firstminute Capital and led by a proven founder who successfully scaled a fintech to £1bn lending, offering high-growth potential in a massive £4bn market.
