Responsibilities
- Lead and collaborate on technical design and architecture decisions within your team's domain

- Own and deliver large projects end-to-end, from initial planning through production deployment and monitoring
- Write comprehensive tests and documentation that enable other engineers to understand, maintain, and extend your work
- Participate in code reviews, providing constructive feedback that elevates code quality and knowledge sharing across the team
- Deliver work that is consistently free of critical bugs before it reaches production, and champion best practices on your team
- Strengthen the systems that produce quality rather than only following them — improve review tooling, test reliability and speed, and the agent skills the whole team depends on, so everyone's output gets better
