The Role:

We are looking for a Senior Platform Engineer with deep specialized knowledge in Kubernetes to architect and scale high-performance, on-premise infrastructure for our clients. You will own the design of internal developer platforms that power mission-critical services. You are the perfect candidate if you are growth-oriented, passionate about technical excellence, and thrive on turning innovative ideas into scalable, production-ready products.

What we are looking for:

• 5+ years of experience with Kubernetes, with a proven track record of managing non-managed (on-prem) clusters.
• Expert knowledge of Helm (v3), including creating custom templates, hooks, and managing complex dependencies.
• Strong proficiency in Terraform and Ansible for provisioning hardware and configuring nodes.
• Deep understanding of CNI providers (Calico, Cilium, or Flannel) and experience managing TLS certificates via Cert-Manager.
• Advanced Linux administration skills (Ubuntu/RHEL), including kernel tuning for high-performance container workloads.
• High proficiency in Go or Python for building custom Kubernetes operators or automation tools.
• Located in CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones.

Responsibilities:

• Architect, deploy, and scale production-grade Kubernetes clusters within our private data centers (Bare Metal or VMware).
• Develop and maintain a library of complex Helm charts to standardize how our teams deploy and manage their applications.
• Use Terraform and Ansible to automate the provisioning and configuration of our physical and virtual infrastructure.
• Implement and tune CNI providers (e.g., Calico or Cilium) and manage enterprise-grade security via RBAC, Network Policies, and Vault.
• Configure CSI drivers for local/distributed storage solutions (Ceph, Longhorn, or NetApp) to ensure data persistence and performance.
• Own the Prometheus/Grafana and ELK stacks to provide deep visibility into cluster health and application metrics.
