Senior DevOps Engineer

About the role

You will help take a new Azure Kubernetes platform from "it works" to production grade. It replaces two legacy environments that run the systems of a German home energy business.

You join 2 client-side DevOps engineers. The engagement is long-term: 6+ months, starting November 2026, with one position open. Work format is hybrid or fully remote.

What you will do

• Own the architecture of the new Azure Kubernetes platform and make design decisions independently (AKS, networking, identity)
• Design the Pulumi abstractions (cluster, network, storage, Key Vault, databases, resource groups) for real production workloads
• Lead the port of the legacy database abstraction
• Design and run the disaster recovery test: the whole environment is recreatable from code after a total loss
• Lead the Datadog to Grafana migration and set the standards for alerts and dashboards
• Design the multi-environment model (production, infrastructure, development, on-demand ephemeral) from one codebase via configuration toggles
• Standardize CI/CD on the cluster and resolve the CI tooling question together with the client's DevOps lead
• Review pull requests, set coding standards, and mentor the Middle engineer

What you bring

• 5+ years of experience
• Solid production Kubernetes experience, building and running the platform other developers deploy to, including upgrades and troubleshooting at depth
• Designed and owned Azure infrastructure end to end: AKS architecture and upgrades, networking (VNet, subnets, private endpoints), identity (Entra ID, managed identities, RBAC), Key Vault, storage. You make architecture calls independently and have planned and tested disaster recovery
• Infrastructure as Code (Terraform is fine, Pulumi is a strong plus), written as real Python with modules, classes, and reusable abstractions that you design yourself
• Deep hands-on knowledge of the Kubernetes ecosystem (GitOps, service mesh / CNI, observability, secrets, policy engines), with the judgment to choose between tools
• CI/CD ownership: you design pipelines, self-hosted runners, and GitOps delivery
• Competent pull request review and the ability to mentor other engineers
• Confident spoken English for direct, daily work with the client team
• Self-directed approach: comfortable with a moving target and an agile way of working

Nice to have

• Pulumi in production
• Istio, Cilium, Argo CD, Kyverno, Kubescape, external-secrets, Kiali
• Grafana stack (dashboards, alerting, tracing) at production quality
• Self-hosted CI runners on Kubernetes
• Cluster-to-cluster migration experience (differing CNIs)
• German (helps with tickets, not required)
