About the role

Key responsibilities & impact
  • Take customer problems from discovery to production inside a pod, engaging directly with customers and shipping in small increments based on customer feedback.
  • Direct AI agents to draft implementations, tests, and migrations; review, integrate, and harden the resulting work.
  • Design and deliver robust production systems with appropriate testing and observability.
  • Work across the codebase, including front end, back end, data, and infrastructure as needed.
  • Move between pods, problems, and streams as priorities change, ramping up quickly in unfamiliar domains.
  • Take accountability for outcomes, raise risks early, and make decisions rather than escalating.
  • Contribute to cross-functional product teams alongside designers and product managers across design, architecture, implementation, and testing.

Requirements

What you’ll need
  • Built and shipped production systems end-to-end, from design through rollout, monitoring, and iteration, where correctness, performance, and resource efficiency mattered.
  • Designed testing and observability for complex behaviour.
  • Worked effectively in a polyglot environment and picked up unfamiliar languages, domains, and codebases quickly.
  • Strong systems experience, for example in Rust, C/C++, or Python, valued.
  • Shipped work outside your strongest layer of the stack, including front end, data layer, or infrastructure.
  • Used AI tools as a serious part of how you build, with judgement to direct, review, and stand behind their output.
  • Applied product and design judgement to engineering work and made sensible decisions under ambiguity.
  • Owned outcomes beyond immediate tasks and took decisions rather than escalating.
  • At Level 5: set technical direction on difficult problems, maintained quality across others' work without becoming a bottleneck, and led cross-cutting or decoupling work adopted by teams.
  • Comfortable experimenting, working directly with non-technical stakeholders, and tackling ambiguous or open-ended problems.
