Job Title: Senior Product Engineer

Salary: £100,000 - £150,000 + Equity

Company Description: Alecto - AI-native law firm backed by Firstminute Capital

Job Description:
Join Alecto as an early engineer to fix the UK’s broken £2.5bn conveyancing market. You will lead a vertical-specific team with P&L accountability, shipping agentic AI workflows that navigate complex legal processes. Working directly with the founder who scaled Gen H to £1bn in lending, you'll shape product direction from day one.

Location: London, UK

Why this role is remarkable:

  • Ship to production in your first week within an autonomous team that operates like a startup-within-a-startup, owning an entire market vertical and its P&L.

  • Join a high-traction venture that hit $2M in annualized revenue just two months after launch, backed by top-tier investors like Firstminute Capital and Mishcon de Reya.

  • Work on high-stakes technical problems building AI agents and LLM-powered systems that go beyond simple prompting to automate complex legal transactions.

What you will do:

  • Design and deploy agentic AI workflows and LLM-powered systems using a modern stack including TypeScript, React, tRPC, Inngest, and GCP.

  • Collaborate directly with users to define product hypotheses and translate fuzzy requirements into high-impact features that solve real-world legal friction.

  • Take full ownership of outcomes by fixing systemic problems, refining AI workflows, and contributing to a high-craft engineering culture with monthly performance reviews.

The ideal candidate:

  • Proven experience at high-growth or early-stage startups with a track record of driving product direction and scaling complex TypeScript projects.

  • Deep technical instinct for building beyond simple prompts, ideally with experience in machine learning or deploying sophisticated AI agents into production.

  • A relentless, low-ego problem solver who thinks in terms of user problems rather than tickets and thrives in environments of high ambiguity and autonomy.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
