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

About This Opportunity

We are representing a confidential e-commerce technology organization seeking a Senior Site Reliability Engineer to join their growing Berlin team. This is a rare opportunity to build a modern private cloud platform on Kubernetes and Harvester—running on dedicated hardware, not managed cloud consoles. You'll help define SRE practices from the ground up, working alongside development teams to enable reliable service delivery for production systems that handle billions of queries annually.

This is a hybrid role based in Berlin, requiring three office days per week.

Responsibilities

• Define and own service level objectives, indicators, and error budgets to drive data-informed reliability decisions
• Lead incident response end-to-end: fast detection, clear communication, blameless postmortems, and structural reduction of incident classes
• Eliminate operational toil through automation and GitOps practices
• Evolve observability capabilities including metrics, logs, traces, alerting, and runbooks across multiple technology stacks
• Contribute to building custom Kubernetes operators and CRDs that make stateful workloads declarative, self-healing, and safely upgradable
• Implement and roll out auto-scaling solutions including HPA, VPA, KEDA, and cluster autoscaling
• Plan capacity, performance, and cost across on-premises and cloud environments, accounting for peak-season loads
• Join the on-call rotation and own reliability topics within your first 90 days

What We're Looking For

Must-have qualifications:

• Production Kubernetes experience building and maintaining clusters on dedicated servers (e.g., kubeadm, RKE2, k3s)—managed-only experience is not sufficient
• Hands-on cluster lifecycle management and upgrade experience
• Lived SRE practice including SLOs, error budgets, incident management, and on-call responsibilities
• Practical experience with GitOps or comparable infrastructure/deployment automation
• Solid observability skills across metrics, logs, traces, and reliable alerting
• Strong automation instinct—you prefer fixing root causes over repeating workarounds
• Collaborative, enabling mindset that views SRE as a service to developers
• Fluent English required

Nice-to-have experience (genuinely optional):

• Harvester, KubeVirt, vSphere/ESXi, OpenStack, or similar virtualization/HCI platforms
• Container storage solutions such as Longhorn or Ceph
• Datacenter networking including load balancing, ingress, and VLAN configuration
• Auto-scaling implementations and capacity/cost planning
• Building Kubernetes operators and custom resource definitions
• German language skills
• Certifications (CKA, CKS) welcome but not required

If you've owned production systems, handled incidents, and worked deeply with Kubernetes—even if your title was never "SRE"—we encourage you to apply. Production experience and engineering mindset matter more than titles.
