Senior Product Engineer at Alecto
Alecto is building the UK’s first AI-native law firm, and they’re looking for a Senior Product Engineer to join their early team in Shoreditch. Backed by Firstminute Capital and led by a founder who scaled a fintech to £1bn in lending, Alecto has already hit $2M ARR just two months post-launch. In this role, you’ll own an entire market vertical, ship agentic AI workflows using TypeScript and tRPC, and have a direct hand in fixing the broken £2.5bn property market. If you want to work at a high-growth startup with real traction, meaningful equity, and elite engineering standards, this is the place.
