We are seeking a highly skilled OpenShift Administration and Deployment Engineer to join our infrastructure team. In this role, you will be responsible for the deployment, configuration, administration, and ongoing maintenance of our Red Hat OpenShift Container Platform environments.

• Cluster Maintenance: Perform routine platform maintenance, including patching, upgrades, capacity planning, and scaling of OpenShift clusters.
• Monitoring & Troubleshooting: Proactively monitor cluster health, performance, and resource utilization. Diagnose and resolve complex infrastructure, network, and application deployment issues.
• Security & Compliance: Implement and manage Role-Based Access Control (RBAC), security context constraints (SCCs), network policies, and identity management integrations.
• Storage & Networking: Configure and manage persistent storage solutions and container networking (e.g., OpenShift SDN, OVN-Kubernetes).
• Collaboration: Work closely with development, QA, and security teams to ensure smooth containerized application deployments and CI/CD pipeline integrations.

Required Qualifications

• Experience: 4+ years of proven experience in installing, configuring, and managing Red Hat OpenShift or Enterprise Kubernetes environments.
• Linux Mastery: Strong background in Linux System Administration (Red Hat Enterprise Linux preferred), including deep knowledge of OS tuning, networking, security, storage management, and troubleshooting.
• Containerization: Solid understanding of container runtimes (CRI-O, Podman, Docker) and container orchestration principles.
• Networking Knowledge: Experience with fundamental network protocols (TCP/IP, DNS, HTTP/HTTPS, Load Balancing) and how they apply to containerized environments.
