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. ## Description * 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). ## Related Videos - [Integrate your Cognitive Assistant with 3rd-party DBs and software](https://www.wearedevelopers.com/videos/249-integrate-your-cognitive-assistant-with-3rd-party-dbs-and-software) - [5 steps for running a Kubernetes environment at scale](https://www.wearedevelopers.com/videos/88-5-steps-for-running-a-kubernetes-environment-at-scale) - [Technical Documentation - How Can I Write Them Better and Why Should I Care?](https://www.wearedevelopers.com/videos/681-technical-documentation-how-can-i-write-them-better-and-why-should-i-care) - [Keycloak case study: Making users happy with service level indicators and observability](https://www.wearedevelopers.com/videos/1599-keycloak-case-study-making-users-happy-with-service-level-indicators-and-observability) - [From Zero to Hero: Launch & Manage Your Cloud Apps with Free OpenShift & Red Hat Developer Hub](https://www.wearedevelopers.com/videos/1023-from-zero-to-hero-launch-manage-your-cloud-apps-with-free-openshift-red-hat-developer-hub) - [All your telemetry data from any source in one place](https://www.wearedevelopers.com/videos/57-all-your-telemetry-data-from-any-source-in-one-place) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Top Big Data Technologies That You Need to Know](https://www.wearedevelopers.com/magazine/108-top-big-data-technologies-that-you-need-to-know) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Learning Kubernetes made easy with KubeCampus](https://www.wearedevelopers.com/magazine/348-learning-kubernetes-made-easy-with-kubecampus) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers)
