Set SLOs/error budgets; instrument with Open Telemetry (logs/metrics/traces); lead incident response, capacity planning, and performance/load testing (k6/JMeter)

Enforce OAuth2/OIDC, service to service auth (mTLS), secrets/KMS, and least privilege access; integrate security checks into CI/CD; maintain auditability
