This role is a remote contractual role. Our work time will be from 1-10 PM PKT.

Key Responsibilities

• Administer and maintain Red Hat Enterprise Linux (RHEL) and Red Hat OpenShift Container Platform (OCP) across the cluster nodes.

• Apply OS and platform patches, security updates, and OpenShift version upgrades in a controlled, low-downtime manner.

• Manage node lifecycle operations (cordon/drain, reboot, replacement, scaling) within OpenShift.

• Maintain and troubleshoot underlying Dell server hardware (PowerEdge or similar), including firmware updates (iDRAC), RAID/storage controllers, and network interfaces.

• Coordinate with the colocation facility in Nebraska for remote hands support, power, cooling, and physical access needs.

• Monitor hardware health (disk, memory, power supplies) and manage vendor support cases/warranty claims with Dell and IBM.

• Manage OpenShift cluster components: control plane, etcd, networking (SDN/OVN), storage classes, and ingress/routing.

• Administer container registries, projects/namespaces, RBAC, and resource quotas.

• Monitor cluster health using OpenShift-native tooling (cluster monitoring stack, Prometheus/Grafana) and respond to alerts.

• Support the IBM Watson deployment (IBM Cloud Pak for Data / "Fusion" stack) running on top of OpenShift, including operator health, storage-backed services, and application pods.

• Work with IBM support and documentation to troubleshoot Watson/Fusion-specific issues, apply IBM-provided patches/fix packs, and manage license entitlements.

• Coordinate planned maintenance windows and upgrades for the Watson/Fusion layer with minimal service disruption.

• Manage persistent storage backing the cluster (e.g., ODF/Ceph, NFS, or SAN-attached storage, depending on the environment).

• Implement and test backup/disaster recovery procedures for cluster configuration, etcd, and application data.

• Maintain network configuration for the private data center environment, including VLANs, firewalls, and load balancers as applicable.

• Apply security hardening in line with Red Hat and IBM best practices; manage certificates, secrets, and access controls.

• Maintain audit logs and support compliance/security review processes as required by the organization.

• Set up and maintain monitoring/alerting for cluster and application health.

• Diagnose and resolve incidents, performing root cause analysis and driving remediation.

• Document cluster architecture, runbooks, and standard operating procedures (this is especially important given the current environment is not well-documented internally).

Required Skills & Experience

• 3+ years of hands-on experience administering Red Hat Enterprise Linux (RHEL) in production environments.

• Solid working experience with Red Hat OpenShift Container Platform administration (cluster operations, oc/kubectl, operators, RBAC, networking).

• Experience with bare-metal server hardware administration (Dell PowerEdge preferred), including iDRAC, firmware, and RAID management.

• Familiarity with container and Kubernetes fundamentals (pods, deployments, persistent volumes, namespaces).

• Experience working in or supporting a private/on-premises data center or colocation environment (as opposed to purely public cloud).

• Understanding of enterprise storage concepts (SAN/NAS, Ceph/ODF, or similar) as used in OpenShift persistent storage.

• Comfort with Linux networking (firewalls, VLANs, DNS, load balancing/ingress).

• Strong troubleshooting and incident response skills, with the ability to work independently in an environment with limited existing documentation.

• Good written communication skills for documentation and vendor coordination (Dell, IBM, Red Hat support).

Preferred / Nice-to-Have

• Direct experience with IBM Cloud Pak for Data, IBM Watson, or IBM Fusion/Fusion HCI appliances.

• Red Hat Certified Specialist in OpenShift Administration (RHCSA/RHCE + OpenShift certs).

• Experience with Ansible for configuration management and automation.

• Familiarity with IBM Storage Fusion / IBM Spectrum or similar hyper-converged infrastructure.

• Experience managing vendor support relationships (Dell ProSupport, IBM Support, Red Hat subscriptions).

• Prior experience in a regulated or high-availability environment where uptime and data locality (private, non-cloud hosting) are critical.
