NBY / TALENT
Kubernetes Engineer
Design, build and migrate production-grade Kubernetes platforms that engineering teams can operate, upgrade and understand without always depending on the same expert.
Key responsibilities
- Design and implement EKS, GKE or AKS clusters with 100% code-defined provisioning (Terraform / Helm).
- Establish GitOps with ArgoCD or Flux: continuous sync, state reconciliation and automated rollbacks.
- Plan and execute migrations with zero-downtime cutover, verifiable rollback plan and complete documentation.
- Improve platform security: RBAC, network policies (Cilium/NetworkPolicy), secrets management and container hardening.
Requirements
- Production Kubernetes operations experience (not just labs): having managed at least 2 real cluster incidents.
- Mastery of Helm, ArgoCD or Flux and container networking fundamentals (CNI, Ingress, Service Mesh).
- Ability to diagnose distributed systems: reading cluster events, node logs and network traces.
- Active freelance / self-employed status with the ability to invoice from Spain or Europe.
What we offer
- Focused, well-defined engagements with rigorous documentation.
- Flexible commitment: part-time or full engagement depending on the project.
- Peer technical review: senior architects involved in every significant decision.
- Rate agreed before starting. Documented scope.
