Backend engineer for home services

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.

• The architecture. Households, properties, partners, suppliers and how they relate.
• State machines every order runs on, clear enough for an agent to act on.
• Contracts between domains, data, queues, infrastructure. You design it and you build it.
• Live voice needs sub-second reads and a platform that doesn't need babysitting.
• Latency budgets per domain, observability shipped with the feature, rollback rehearsed every release, small changes to production daily.
• You'll move live systems onto a modern stack without dropping anything.
• Permissioned access for Jay and partner agents to read and act, with idempotency, audit trails and a hard line around money.
• Config over code, so commercial teams change pricing without a deploy.
• How you work becomes how engineering works.

• 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
• Будет плюсом: 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

• Cash competitive, plus equity
• Crunch time means late nights and weekends. In general, great work-life balance.
