You enable teams through self-service capabilities, strong CI/CD foundations and GitOps workflows. You continuously improve the platform with a strong focus on security, reliability, observability and operational excellence.

You also play a mentoring role, supporting junior engineers through code reviews, pairing and technical guidance. In addition, you contribute to defining SLOs and SLIs, incident analysis and improvements that reduce MTTR across the platform.

Nice to have:
