Senior Site Reliability Engineer / SRE – Kubernetes & Hybrid Cloud (m/f/d)

Your profile

• Languages: Fluent English required; German is a plus, not a must

Your profile

Must-haves:

• Kubernetes in production – built, not just used: you've set up and maintained clusters on your own servers (e.g. kubeadm, RKE2, k3s) and know cluster lifecycle and upgrades – managed-only experience isn't enough for this role
• Lived SRE practice: SLOs, error budgets, incident management, on-call
• Hands-on experience with GitOpsor comparable infrastructure/deployment automation – experience with Argo CD or Flux is a strong plus
• Solid observability skills – metrics, logs, traces, alerting that people trust
• A strong automation instinct – you'd rather fix a problem's cause than repeat its workaround
• A collaborative, enabling mindset – you see SRE as a service to our developers: you ask what they need, discuss trade-offs openly, and don't fall in love with your own solution

Nice-to-haves (genuinely optional – we'll teach you the rest):

• Harvester, KubeVirt, vSphere/ESXi, OpenStack or similar virtualization/HCI platforms
• Container storage (Longhorn, Ceph) and datacenter networking (load balancing, ingress, VLAN)
• Auto-scaling (HPA, VPA, KEDA, cluster auto scaler) and capacity/cost planning
• Experience building Kubernetes operators/CRDs
• German language skills Certifications (CKA, CKS) are welcome but no substitute for hands-on experience – in the tech interview we'll ask about what you've actually built and operated.

You don't tick every box – or your title was never “SRE”? Apply anyway. If you've owned production systems, handled incidents and worked deeply with Kubernetes, we want to hear from you – production experience and engineering mindset matter more to us than titles or buzzwords.
