AI Engineer (Lex)
AIFull-timeRemote£150,000
Make Lex, each side's private assistant, draft, explain and redline contracts well, and prove it with evals.
What you'll do
- Build how Lex drafts from one sentence, explains every clause in plain language and proposes faithful redlines.
- Write the evals: is the explanation right, is the redline faithful, does it stay neutral to both sides?
- Keep Lex private to each side. It drafts and explains; it never sends or signs.
Who you are
- You've built and measured LLM features in production, not just demos.
- You'd rather write a good eval than a clever prompt.
- You know how to make models fast, cheap and reliable at scale.
What we offer
- Pay stated up front on every role. No negotiation games.
- Fully remote. Work from wherever you do your best work.
- Real ownership of a whole part of the product from day one.
- Work directly with the founder. Short loops, no layers.
- We build in public, so your work is seen.
