Job Summary
We are looking for a Senior DevOps & Kubernetes Engineer with deep, hands-on expertise across Azure DevOps pipelines, Kubernetes platform engineering, and hybrid cloud infrastructure spanning AKS, Rancher/SUSE, VMware, and Nutanix. The ideal candidate has operated production-grade container platforms at scale -- owning everything from pipeline authoring and pod lifecycle management to storage drivers, ingress, and load balancing -- and can troubleshoot deep Kubernetes internals and networking issues independently.
Essential Duties and Responsibilities
CI/CD with Azure Pipelines – Design, author, and maintain enterprise-scale Azure DevOps pipelines (YAML, multi-stage, templates, variable groups, environments, approvals, self-hosted agent pools). Drive release management, artifact promotion, and deployment strategies (blue/green, canary, rolling).
Kubernetes Platform Engineering – Operate production Kubernetes clusters across AKS, Rancher (RKE2/K3s), and SUSE Rancher Prime. Manage cluster lifecycle, upgrades, node pools, taints/tolerations, affinity rules, PodDisruptionBudgets, and HPA/VPA/Cluster Autoscaler.
Pod & Workload Management – Deep troubleshooting of pod scheduling, init containers, sidecars, probes (liveness/readiness/startup), resource requests/limits, QoS classes, OOMKills, eviction, and CrashLoopBackOff scenarios. Tune kubelet, container runtime (containerd), and cgroup behavior.
Networking (Cluster & Infra) – Design and operate cluster networking using CNI plugins (Calico, Cilium, Azure CNI), NetworkPolicies, service meshes (Istio/Linkerd), CoreDNS, kube-proxy/IPVS, and east-west traffic flows. Own ingress controllers (NGINX, Traefik, Istio Gateway) and integrate with external/internal load balancers (Azure LB, MetalLB, F5, NSX ALB/Avi).
Storage & CSI Drivers – Implement and operate persistent storage with CSI drivers including Azure Disk/File CSI, VMware vSphere CSI, Nutanix CSI, Longhorn, and Rook/Ceph. Manage StorageClasses, VolumeSnapshots, dynamic provisioning, topology-aware scheduling, and storage migration.
Hybrid & On-Prem Platforms – Run Kubernetes on VMware vSphere (with vSphere CSI/CPI), Nutanix AHV/Karbon, and bare-metal SUSE. Coordinate with virtualization, SAN/NAS, and network teams for capacity, datastore, and fabric design.
Load Balancing & Ingress – Architect L4/L7 load balancing across cloud (Azure Load Balancer, Application Gateway, Front Door) and on-prem (F5 BIG-IP, NSX ALB, MetalLB, kube-vip). Manage TLS termination, SNI, mTLS, WAF, session affinity, and health probes.
Infrastructure as Code & GitOps – Build reusable IaC with Terraform and Helm. Implement GitOps with Argo CD or Flux for declarative cluster and application delivery.
Observability & SRE – Stand up and operate Prometheus, Grafana, Loki, Alertmanager, and OpenTelemetry. Define SLIs/SLOs, drive incident response, post-mortems, and capacity planning.
Security & Compliance – Enforce Pod Security Standards, RBAC, OPA/Gatekeeper or Kyverno policies, image signing (Cosign), secret management (Key Vault, External Secrets, SealedSecrets), and CIS benchmark hardening.
Scripting proficiency in Python, Bash, PowerShell, and experience in using git, github projects
