The roleYou'll be the senior engineer on our high value and complex builds, embedded inside client teams from week one.
You own the architecture for agentic systems, data pipelines and integrations, ship them to production, and raise the standards of the engineering team around you.

You'll be involved across the full arc.
Location: Remote (UK), with optional access to a number of London-based co-working spaces.
What you'll doTake a build end to end: architecture, implementation, deployment and handover.
Design production AI systems, agents, retrieval, evaluation and the data plumbing underneath them.
Work alongside client engineering teams, and directly with Nick and Mark, with no layer in between.
Mentor and support our AI and graduate engineers, sharing what you know as the team grows.
What we look forAround 5+ years shipping production software, with real ownership of systems in the wild.
Strong Python plus at least one typed language, and sound judgement on when to reach for which.
Hands-on with LLMs and agents, plus cloud, data pipelines and good testing discipline.
Comfortable client-facing, communicating clearly and understanding what clients need.
An appetite for working in an inclusive team, alongside people whose backgrounds and lived experiences differ from your own.
