- Lead deep troubleshooting activities:
- cluster degradation, node failures, API instability, etcd performance issues
- networking issues (ingress, routes, DNS, CNI, service connectivity)
- storage issues (persistent volumes, performance bottlenecks, CSI failures)
- workload failures (pods, operators, deployments, stateful applications).
- Provide clear technical updates during incidents, including impact assessment, recovery plan/ workaround, risks and next steps.
- Plan and execute OpenShift lifecycle activities such as version upgrades (cluster upgrades and operator upgrades), patching and security hardening and certificate management and renewal processes.

- Develop and maintain operational documentation, including troubleshooting guides, standard operating procedures (SOPs), build standards and reference architectures, operational runbooks for recurring tasks.
- Support automation initiatives using tools such as: Ansible / Automation Platform (preferred), GitOps practices (ArgoCD) where applicable and scripting (Bash / Python) to reduce manual operations.
- Proactively identify improvements to increase platform stability, recovery speed (MTT), repeatability and reduction of human error.
- Support and improve observability across the platform, including:
- OpenShift monitoring stack (Prometheus / Alertmanager / Grafana)
- log management (e.g., EFK / Loki or enterprise logging platforms).
- Troubleshoot performance issues related to compute resource constraints, scheduling and resource requests/limits and cluster scaling and capacity planning.
- Work with customer stakeholders and internal teams to define alert thresholds, reduce noise and false positives and improve operational dashboards and health reporting.
- Ensure the platform is operated in a secure manner aligned with enterprise expectations:
- RBAC best practices
- integration with enterprise identity providers (LDAP / AD / SSO)
- secure cluster configuration and segregation
- Support vulnerability remediation and platform hardening initiatives
- Collaborate with Security teams for audits, compliance requests, and evidence collection.
Mandatory Technical Skills:
- Strong hands-on experience with Red Hat OpenShift administration and operations.

- Solid understanding of Kubernetes fundamentals: pods, deployments, services, ingress, namespaces, RBAC, operators.
- Experience troubleshooting infrastructure-related issues across compute, network, storage, and platform services.
- Experience working in production environments with uptime and SLA commitments.
- Proven ability to operate as Level 3 support, including deep troubleshooting, structured root cause analysis and ownership until resolution.

- GitOps tools (ArgoCD)
- Infrastructure as Code practices.
- Experience with enterprise storage and CSI integrations.
- Experience with enterprise networking topics (DNS, routing, firewall constraints, load balancing).

- Red Hat Certified Specialist in OpenShift Administration (preferred)
- Red Hat Certified Engineer (RHCE) (strong advantage)
- Kubernetes certifications (CKA/CKAD) (nice to have).
- Work in an operational environment following ITIL practices (Incident / Problem / Change Management) and managed services delivery model and SLA commitments.
