L4 SME Red Hat OpenShift Enterprise Admin

You are a Senior-Level Subject Matter Expert (L4) specializing in Red Hat OpenShift Enterprise Administration within the Telco domain, with a focus on bare metal deployments. Your primary responsibility is to manage and enhance Telco-grade workloads for a global Tier-1 telecommunications provider, ensuring platform resilience, lifecycle governance, and continuous integration across critical services. Your key responsibilities include serving as the OpenShift Bare Metal Admin SME for complex Telco workloads on private cloud infrastructure, overseeing end-to-end deployment, scaling, and lifecycle operations of Red Hat OpenShift on bare metal environments, and owning upgrade readiness and rollback strategies. You will collaborate closely with OEM vendors for platform bug RCA and patch governance, enable monitoring, alerting, compliance enforcement, and automation for large-scale cluster environments, and ensure platform alignment with Telco service and regulatory requirements in coordination with network, security, and architecture teams. Additionally, you will be responsible for integrating with CI/CD pipelines, GitOps, observability frameworks (such as Prometheus and Grafana), and ITSM tools, driving operational maturity through SOP creation, audit compliance, RCA publishing, and incident retrospectives, as well as mentoring junior engineers and reviewing configurations impacting production-grade OpenShift clusters. To excel in this role, you must have at least 8 years of direct experience managing Red Hat OpenShift v4.x on bare metal, strong expertise in Kubernetes, SDN, CNI plugins, CoreOS, and container runtimes (CRI-O/containerd), experience with BIOS provisioning, PXE boot environments, and bare metal cluster node onboarding, as well as familiarity with Telco Cloud principles, especially NFV/CNF workloads. Proficiency in RHEL administration, Ansible automation, Terraform (optional), and compliance remediation is essential, along with an understanding of storage backends (preferably Ceph), NTP/DNS/syslog integration, and cluster certificate renewal processes. Moreover, hands-on experience with Red Hat Satellite, Quay, multi-tenant OpenShift workloads, and security features like SELinux, SCCs, RBAC, and namespace isolation is required. Preferred certifications include Red Hat Certified Specialist in OpenShift Administration (EX280), Red Hat Certified System Administrator (RHCSA), and Certified Kubernetes Administrator (CKA) as a bonus.,
