OpenShift Administrator

Overview

We are looking for a mid-level OpenShift Administrator to install, secure, and operate Red Hat OpenShift Container Platform (OCP) clusters across on-premises, hybrid, and multi-cloud environments — ensuring high availability, security compliance, and operational efficiency for containerized workloads.

Responsibilities

• Install, configure, and administer OpenShift Container Platform (OCP 4.x) clusters across on-prem, hybrid, and multi-cloud environments.
• Perform cluster lifecycle operations — scaling, zero-downtime upgrades, node management, and Operator Lifecycle Manager (OLM) administration.
• Configure and manage RBAC, projects/namespaces, and multi-tenancy for secure, isolated team environments.
• Implement and enforce Security Context Constraints (SCC), network policies, image scanning, and CIS benchmark compliance.
• Set up centralized logging and monitoring using Prometheus, Grafana, and the EFK/Loki stack for cluster and workload observability.
• Manage persistent storage (OpenShift Data Foundation/Ceph, NFS, cloud-native storage) and backup/DR using tools such as Velero.
• Diagnose and resolve cluster, node, pod, and networking issues across the platform.
• Automate day-2 operations using Ansible and GitOps practices (ArgoCD/OpenShift GitOps).
• Support application teams with containerization, onboarding, and deployment best practices.
• Manage resource quotas, limit ranges, and cost/capacity optimization across clusters.

•

Qualifications

• Bachelor's degree in Computer Science, Information Technology, or a related field.
• 4–7 years of overall experience in Kubernetes/container platform administration, including at least 2 years working directly with OpenShift.

Essential skills

• Strong hands-on experience administering Red Hat OpenShift Container Platform (OCP 4.x).
• Deep understanding of Kubernetes architecture, objects, and cluster administration.
• Solid Linux administration skills (RHEL/CoreOS) including networking and storage fundamentals.
• Knowledge of container security practices — SCC, network policies, image/vulnerability scanning.
• Experience with monitoring and logging stacks — Prometheus, Grafana, EFK/Loki.
• Familiarity with GitOps tooling (ArgoCD/OpenShift GitOps) and Ansible-based automation.
• Understanding of storage solutions such as ODF/Ceph, NFS, or cloud-native persistent storage.

Desired skills

• Red Hat Certified Specialist in OpenShift Administration (EX280) or Red Hat Certified Engineer (RHCE).
• Experience with multi-cluster management using Red Hat Advanced Cluster Management (ACM).
• Exposure to CI/CD integration with OpenShift via Tekton, Jenkins, or GitHub Actions.
