What you'll do
- Taking a customer problem from discovery to production inside a pod, getting close to customers yourself, framing the problem, and shipping in small increments guided by real customer signal rather than internal opinion.
- Directing AI agents to draft implementation, tests, and migrations, then reviewing, integrating, and hardening that work; writing intent precisely enough to brief both a teammate and an agent, and owning correctness and maintainability regardless of how the first draft was produced.
- Designing and delivering robust production systems where correctness, performance, and resource efficiency matter, with the tests and observability that make complex behaviour safe to evolve.
- Working across the codebase wherever the problem leads, including areas your pod doesn't steward, with stewards looped in proportionate to the risk rather than handing work off and waiting.
- Moving between pods, problems, and streams as priorities change, ramping fast on unfamiliar domains and leaving what you built running well behind you.
- Taking full accountability for outcomes rather than just your code changes: raising risks early, and deciding rather than escalating.
What we're looking for
- Built and shipped production systems end-to-end, from design through rollout, monitoring, and iteration, in settings where correctness, performance, and resource efficiency mattered.
- Designed testing and observability that made complex behaviour understandable, debuggable, and safe to evolve.
- Worked effectively in a polyglot environment, choosing the right tool for the problem and picking up unfamiliar languages, domains, and codebases fast.
- Strong systems experience, for example in Rust, C/C++, or Python.
- Shipped work outside your strongest layer of the stack when the problem needed it, picking up the front end, the data layer, or the infrastructure rather than waiting for someone else to.
- Used AI tools as a serious part of how you build, with the judgement to direct, review, and stand behind what they produce.
- Carried product and design judgement into your engineering work, shaping the solution rather than only implementing a spec and making sensible calls under ambiguity.
- Owned outcomes beyond your immediate task, taking decisions rather than escalating them.
Benefits
- £5,000 training and conference budget for individual and group development.
- 25 days of holiday plus 8 bank holidays (33 days total).
- Company pension scheme via Penfold.
- Mental health support and therapy via Spectrum.life.
- Individual wellbeing allowance via Juno.
- Private healthcare insurance through AXA.
- Income protection and Life Insurance.
