You are fluent in Helm and GitOps tooling (ArgoCD or Flux); you write charts from scratch, not just deploy them. You are comfortable with PostgreSQL operations: replication, backup/restore, connection pooling, and performance tuning under load. You have experience with Infrastructure as Code and treat every manual click as technical debt. You know your way around an observability stack, writing PromQL, building Grafana dashboards, and designing alert thresholds that fire when it matters.

Ideally, you have worked in a regulated or compliance-sensitive environment (healthcare, finance, government) where auditability and data protection are non-negotiable. You communicate clearly in English; German is a plus but not required.
