About the Role:
We are building and running mission-critical production infrastructure on Kubernetes. As a Senior Kubernetes Engineer, you will own the full stack - from the underlying OS and container runtime through networking, storage, and the cluster control plane itself. You will engage across the full lifecycle: architecture, deployment, hardening, and day-2 operations for multi-cluster, multi-tenant environments. This is hands-on infrastructure work with direct ownership of production reliability.
What you will be doing:
• Design, deploy, and operate production-grade Kubernetes clusters across bare-metal, cloud, and hybrid environments.
• Manage cluster lifecycle end-to-end: provisioning, version upgrades, patching, scaling, and capacity planning
• Architect and run multi-cluster/multi-tenant setups using Kamaji, Rancher (hosted control planes), and vCluster (virtual clusters)
• Configure and troubleshoot CNI plugins (Calico, Cilium) — pod networking, network policies, BGP, and eBPF dataplanes.
• Own cluster DNS (CoreDNS) configuration, service discovery,
and resolution troubleshooting.
• Manage container runtime (containerd, CRI-O) and underlying OS: Linux tuning, kernel/sysctl parameters, systemd, cgroups
• Deploy and operate service mesh (Istio, Cilium mesh) for traffic management
• Manage persistent storage: PV/PVC, StorageClasses, CSI drivers (Rook/Ceph, Longhorn, cloud-native CSI)
• Own the network stack: ingress controllers, load balancing, MetalLB/BGP, firewalling, and network troubleshooting
• Implement GitOps and Infrastructure-as-Code (ArgoCD/FluxCD, Terraform, Helm) for cluster and workload delivery
• Harden clusters: RBAC, Pod Security Standards, network policies, secrets management (Vault, Sealed Secrets), image scanning
• Own backup and disaster recovery (Velero, etcd snapshotting) and run DR drills
• Provide on-call production support: monitor cluster health, troubleshoot incidents, and drive root-cause resolution
• Create comprehensive docume
