Job Description:

We are looking for an experienced OpenShift Administrator / Platform Engineer to manage, operate, and evolve our Red Hat OpenShift Container Platform (OCP) environment. You will be responsible for the day-to-day administration, performance, security hardening, and lifecycle management of OpenShift clusters supporting mission-critical enterprise workloads. Working closely with DevOps, application, and infrastructure teams, you will ensure platform reliability, availability, and compliance across on-premise and hybrid cloud environments.

Key responsibilities

• Install, configure, upgrade, and maintain Red Hat OpenShift Container Platform (OCP 4.x) clusters across on-premise, bare metal, and hybrid cloud environments.
• Manage cluster lifecycle operations — node scaling, version upgrades, patching, certificate rotation, and capacity planning.
• Administer OpenShift projects, namespaces, RBAC policies, service accounts, and resource quotas to enforce governance and multi-tenancy standards.
• Design and implement networking configurations including SDN/OVN-Kubernetes, Ingress controllers, Routes, Network Policies, and Load Balancers.
• Manage persistent storage solutions — configure and maintain OpenShift Data Foundation (ODF), Ceph, NFS, and dynamic provisioning via StorageClasses and PVCs.
• Implement and enforce platform security policies — Pod Security Admission (PSA), Security Context Constraints (SCC), TLS certificate management, image signing, and vulnerability scanning using ACS (Advanced Cluster Security / StackRox).
• Build, maintain, and optimise CI/CD pipelines integrated with OpenShift — using Tekton Pipelines, OpenShift GitOps (ArgoCD), Jenkins, and GitHub Actions.
• Monitor cluster health, performance, and resource utilisation using Prometheus, Grafana, Alertmanager, and EFK/ELK stack — setting up dashboards and alerts for proactive incident management.
• Provide L3 support for platform incidents — root cause analysis, troubleshooting cluster, networking, storage, and application deployment issues.
• Develop and maintain automation scripts and IaC templates using Ansible, Terraform, and Helm for platform provisioning and configuration management.
• Collaborate with application teams to onboard workloads, define deployment standards, and provide OpenShift best practice guidance.
• Ensure platform compliance with enterprise security policies, audit requirements, and regulatory frameworks (MAS TRM where applicable).
• Produce and maintain platform documentation — runbooks, architecture diagrams, capacity plans, and operational procedures.

Requirements

• 5+ years of hands-on experience in Linux infrastructure and container platform administration, with at least 3 years focused on Red Hat OpenShift (OCP 4.x).
• Deep expertise in Kubernetes fundamentals — Pods, Deployments, StatefulSets, DaemonSets, Services, ConfigMaps, Secrets, Ingress, and RBAC.
• Strong understanding of OpenShift-specific components — Operators, OLM (Operator Lifecycle Manager), MachineConfigOperator, Image Streams, BuildConfigs, and DeploymentConfigs.
• Proficiency in Linux system administration (RHEL / CentOS / CoreOS) — networking, storage, performance tuning, and security hardening.
• Hands-on experience with OpenShift networking — OVN-Kubernetes, SDN, Ingress controllers, Routes, and Network Policies.
• Experience with persistent storage solutions — OpenShift Data Foundation (ODF), Ceph RBD/CephFS, NFS, and dynamic PVC provisioning.
• Proficiency in CI/CD tooling integrated with OpenShift — Tekton, ArgoCD (OpenShift GitOps), Jenkins, or GitHub Actions.
• Experience with monitoring and observability — Prometheus, Grafana, Alertmanager, and log aggregation (EFK / Loki).
• Strong scripting skills — Bash, Python, or Ansible for automation and platform management tasks.
• Experience with Infrastructure as Code — Terraform, Ansible, or Helm charts.
• Familiarity with container security tools — ACS/StackRox, Trivy, Clair, or Quay image scanning.
• Red Hat Certified OpenShift Administrator (EX280) or Red Hat Certified Engineer (RHCE) certification is strongly preferred.
