Responsibilities

  • Take architectural ownership of shared infrastructure services (API gateway, storage, secrets, security, observability).
  • Work with and improve existing, partially documented systems, identifying and remediating weak points.
  • Evaluate aging components, deciding on fixes, replacements, or retirement based on build-vs-buy reasoning.
  • Design and establish an on-call process, including runbooks for platform and infrastructure incidents.
  • Mature observability practices, rolling out distributed tracing, SLOs/SLIs, and dashboards.
  • Apply system design fundamentals (load balancing, caching, sharding, replication) to new and existing services.
  • Advise across teams on shared infrastructure services and document knowledge consistently.
  • Actively distribute critical know-how to reduce single points of failure.

Requirements

  • 7+ years of experience in platform, infrastructure, or SRE roles, ideally with private cloud/IaaS responsibility.
  • Hands-on production experience with distributed storage systems (Ceph) and Kubernetes persistent storage (Longhorn or comparable).
  • Experience operating API gateways and ingress (Kong, Nginx Ingress, or comparable), including debugging cross-cutting concerns.
  • Experience with CDN/edge security, DDoS mitigation, WAF configuration (e.g., Cloudflare), and firewall-rule design.
  • Strong grounding in system design fundamentals (load balancing, caching, sharding/replication, consistency models).
  • Experience designing or maturing observability (tracing, metrics, SLOs/SLIs) with Prometheus, Grafana, OpenTelemetry.
  • Experience with secrets/identity infrastructure (Vault, Keycloak), messaging systems (NATS), and building on-call processes.
  • Professional fluency in English; German language skills, CKA/CKS, Ceph training, and virtualization experience are a plus.
