Staff or Senior Product Engineer
Salary
£100k-£150k + Equity
Company Description
Alecto is a London-based legal-tech startup backed by Firstminute Capital, building the UK's first AI-native law firm. Led by a founder who scaled Gen H to £1bn in annual lending, Alecto is disrupting the £4bn conveyancing market by replacing opaque, paper-heavy processes with advanced AI agents and regulated legal workflows.
Job Description
As an early product engineer at Alecto, you will build the platform’s core architecture from the ground up. You’ll work directly with the founder and senior engineers to ship AI agents that automate complex legal tasks. This is a high-ownership role where you’ll shape product direction and deploy production-ready code within your first week.

Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

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.
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.
- Develop and refine AI agents using LLMs and RAG techniques to automate the slow, paper-heavy workflows of traditional UK conveyancing.
- Engage directly with users to identify problems, form hypotheses, and iterate rapidly to define the product roadmap alongside the founding team.
