About the role
We're hiring a Lead Backend Engineer to design a global, agentic-first platform for moving and home life — fast enough for live voice, reliable enough for agents to act on their own. We are looking for a truly world-class engineer who has seen what great looks like and can take ownership to build the foundations for a global agentic marketplace.
The opportunity: OpenClaw meets Amazon, for your home. Moving is the second most stressful thing most people do, and the admin never stops. Jay is the personal AI that takes it off your plate.
Responsibilities
•Design households, properties, partners, suppliers and how they relate
•Build state machines every order runs on, clear enough for an agent to act on
•Define contracts between domains, data, queues, infrastructure — you design it and you build it
•Deliver sub-second reads for live voice on a platform that doesn't need babysitting
•Set latency budgets per domain, ship observability with each feature, rehearse rollback every release, and make small changes to production daily
•Move live systems onto a modern stack without dropping anything
•Build permissioned access for Jay and partner agents to read and act, with idempotency, audit trails and a hard line around money
•Favor config over code, so commercial teams can change pricing without a deploy
•Shape how engineering works through how you work
Requirements
•You're a systems thinker first: how the parts interact, where failure hides, what breaks at ten times the volume
•You've architected real systems end to end, more than once, and run them in production at the scale of millions of users
•You take the edges seriously: retries, idempotency, backpressure, the message that arrives twice
•You raise everyone around you; the standard goes up on work you never touch
•You are great to work with and will make work more joyful
•You're AI-native at the frontier, and you set the practice for the team, from planning to evals
•You're strong in TypeScript, productive in whatever a problem needs within days, and happiest thinking out loud with the team
•UK right to work required
Nice to have
•You've led a team, or worked in UK property or utilities
•You've moved house in the UK and it made you angry — we want the specific story
•You already have ideas about how it should work — bring them to the first call
Conditions
•Cash competitive, plus equity
•Work hard, play hard — crunch time means late nights and weekends; in general, great work-life balance
•Hybrid format in London
