About the role

Key responsibilities & impact
  • Take customer problems from discovery to production inside a pod
  • Engage directly with customers, frame problems, and ship small increments guided by customer feedback
  • Direct AI agents to draft implementation, tests, and migrations
  • Review, integrate, and harden AI-generated work while owning correctness and maintainability
  • Design and deliver robust production systems with attention to correctness, performance, and resource efficiency
  • Build tests and observability to make complex behaviour safe to evolve
  • Work across the codebase, including front end, back end, data, and infrastructure as needed
  • Move between pods, problems, and streams as priorities change
  • Ramp quickly on unfamiliar domains and codebases
  • Take accountability for outcomes, raise risks early, and make decisions rather than escalating
  • Set technical direction on hard problems and enable other engineers to work faster and safer
  • Maintain quality standards across other people's work without becoming a bottleneck
  • Lead cross-cutting or decoupling initiatives adopted by teams

Requirements

What you’ll need
  • Built and shipped production systems end-to-end, from design through rollout, monitoring, and iteration

  • Strong systems experience, for example in Rust, C/C++, or Python, valued
  • Experience shipping outside your strongest layer of the stack, including front end, data layer, or infrastructure
  • Experience using AI tools seriously in software development, with judgement to direct, review, and stand behind their output
  • Product and design judgement applied to engineering work
  • Ownership of outcomes and decision-making without unnecessary escalation
  • At Level 5: set technical direction on hard problems; hold quality standards across others' work; lead cross-cutting or decoupling work adopted by teams
  • Comfortable working directly with non-technical stakeholders
  • Comfortable with ambiguous and open-ended problems
  • Willing and able to work from the office 2–3 days per week in a hybrid model
  • Legal right to work in the country where the role is based
