Senior Site Reliability Engineer (SRE) – Kubernetes & Hybrid Cloud Overview We are building a modern private cloud platform on Kubernetes and Harvester, on-prem by default with elastic bursts into the public cloud and the option to go cloud-only later. As a Senior SRE, you will shape our SRE practice, working alongside our Berlin development teams while two system administrators in Pforzheim manage the hardware. Tech stack Kubernetes on our own servers (kubeadm, RKE2, or k3s), Harvester, KubeVirt, Argo CD/Flux, Prometheus/Grafana, Longhorn/Ceph. Responsibilities - Define and own SLOs, SLIs, and error budgets; drive data-informed reliability decisions - Lead incident response end-to-end: fast detection, clear communication, blameless postmortems - Eliminate toil through automation and GitOps; evolve observability across two stacks - Help build a Kubernetes operator (CRDs) to make stateful search clusters declarative, self-healing and upgradable; roll out auto-scaling (HPA/VPA/KEDA/clusterautoscaler) - Plan capacity, performance and cost across on-prem and cloud; support large seasonal loads for merchants Requirements - Production Kubernetes experience; you’ve set up and maintained clusters on your own servers - Lived SRE practice: SLOs, error budgets, incident management, on-call - Hands-on GitOps/infrastructure automation; Argo CD or Flux is a strong plus - Strong observability skills; reliable metrics, logs, traces, and alerting - Automation mindset; prefer solving root causes over applying quick workarounds - Colla
