- Take customer problems from discovery to production within a small pod, using direct customer feedback to guide incremental delivery.
- Direct AI agents to draft implementations, tests, and migrations, then review, integrate, and harden the resulting work.
- Design and deliver robust production systems with strong correctness, performance, resource efficiency, testing, and observability.
- Work across front end, back end, data, and infrastructure wherever the problem requires.
- Move between pods, problems, and streams as priorities change while leaving shipped systems running well.
- Own outcomes end to end, raise risks early, and make decisions rather than escalating them.

- Experience owning outcomes beyond immediate implementation tasks.
- For Level 5, experience setting technical direction, raising the quality bar across other engineers’ work, and leading adopted cross-cutting initiatives.
