Building autonomous AI agents that handle real-world jobs in trades and field services.

Staff Software Engineer

UKOn-site£150K - £250K5 - 10 years
We're a small, well-funded team that believes the next wave of AI won't live in a chat window — it will book jobs, dispatch crews, and negotiate with suppliers while the humans sleep. We're building reasoning agents that operate across phone, email, and industry-specific tooling, tackling the messy, high-stakes workflows that keep the physical economy moving. This role sits at the center of that effort, shaping both the agent architecture and the platform that serves thousands of service businesses.

What they're looking for

  • 5+ years building and shipping full-stack software, with deep fluency in Python and TypeScript
  • Experience designing and operating distributed systems on Kubernetes in a production environment
  • Track record of integrating large language models into products, not just experiments — you've wrestled with latency, reliability, and the quirks of model behavior
  • Comfortable owning technical decisions across backend, frontend, and infrastructure in a small, high-trust team
  • Clear, direct communication and a bias for putting working software in front of users quickly
