Primary Title: Kubernetes Administrator

Industry & Sector: Cloud Infrastructure & DevOps — Platform Engineering and Managed Container Orchestration services that operate production-grade Kubernetes clusters for enterprise applications. The role focuses on building reliable, secure, and scalable platform operations to accelerate developer delivery and ensure high-availability for critical workloads.

About the Opportunity

We are hiring an experienced Kubernetes Administrator to own cluster operations, automation, and platform reliability for on-premise and cloud environments. This on-site role in India is ideal for hands-on operators who enjoy system-level troubleshooting, infrastructure-as-code, and improving platform maturity across CI/CD, observability, and security.

Role & Responsibilities
  • Operate and maintain production Kubernetes clusters (deployment, upgrades, scaling, and lifecycle management) to meet SLAs and uptime targets.
  • Design and implement infrastructure-as-code for cluster provisioning and platform components using Terraform, eksctl or kubeadm and Helm charts.
  • Manage container lifecycle, image registries, and integrate clusters with CI/CD pipelines and GitOps workflows (ArgoCD/Jenkins/GitLab).
  • Implement monitoring, logging and alerting stacks (Prometheus, Grafana, ELK/Fluentd) and troubleshoot performance, networking, and storage issues.
  • Enforce platform security and compliance: RBAC, Network Policies, Pod Security Standards, secret management and image scanning.
  • Automate operational runbooks (backups, restore, cluster upgrades), perform capacity planning and document procedures to reduce MTTR.
Skills & Qualifications

Must-Have

  • Proven experience administering production Kubernetes clusters (EKS/AKS/GKE or on-prem).
  • Strong container tooling experience including Docker and container registries.
  • Experience with Helm and authoring/maintaining Helm charts.
  • Hands-on with infrastructure-as-code tools such as Terraform or eksctl.
  • Experience implementing monitoring and observability using Prometheus and Grafana.
  • Solid Linux system administration and networking fundamentals (CNI, network policies, storage integration).

Preferred

  • Certified Kubernetes Administrator (CKA) or Certified Kubernetes Application Developer (CKAD).
  • Experience with service mesh technologies such as Istio or Linkerd and multi-cluster operations.
  • Exposure to GitOps, ArgoCD and advanced cluster security (image scanning, runtime security).
Benefits & Culture Highlights
  • On-site role with opportunities for professional growth, hands-on ownership, and certification support.
  • Collaborative engineering culture focused on automation, operational excellence, and continuous improvement.
  • Work on critical infrastructure powering high-availability enterprise applications with clear impact.

Location: India (On-site)

To apply, bring evidence of production Kubernetes ownership, automation artifacts (Terraform/Helm), and examples of troubleshooting/incident remediation you led.
