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.
