Responsibilities
- Take customer problems from discovery through production within a pod, using customer feedback to guide incremental delivery.
- Direct AI agents to draft implementation, tests, and migrations, then review, integrate, harden, and own the resulting work.
- Design and deliver robust production systems with appropriate testing, observability, performance, correctness, and resource efficiency.
- Work across front-end, back-end, data, and infrastructure areas wherever the problem requires.
- Move between pods, problems, and streams while ramping quickly on unfamiliar domains and leaving systems operating well.
- Take accountability for outcomes, raise risks early, and make decisions rather than escalating them.
- Set technical direction on difficult problems, maintain quality standards across other engineers’ work, and lead cross-cutting or decoupling initiatives.
Requirements
- Experience building and shipping production systems end-to-end from design through rollout, monitoring, and iteration.
- Experience designing testing and observability for complex, debuggable, and safely evolvable systems.

- Experience using AI tools seriously in software development, with the judgment to direct, review, and take responsibility for their output.
- Ability to apply product and design judgment, shape solutions under ambiguity, and work directly with non-technical stakeholders.
- Experience owning outcomes beyond an immediate task and making decisions rather than escalating them.
- For Level 5, experience setting technical direction, raising the quality bar across other engineers’ work, and leading cross-cutting work adopted by teams.
