- Improve shared orchestration frameworks when issues affect multiple controllers.
- Work with systems teams, scientists, operators, and other software teams that depend on the services.
- Strengthen observability, health checking, and alerting.
- Review code and help less experienced engineers develop while remaining hands-on.
