Job Description
We are urgently seeking a highly experienced SC Cleared Red Hat OpenShift Platform SME with deep hands-on expertise in building, configuring, securing, and operating OpenShift environments.

o Authentication & identity integration
o Image security, registry controls, and policy enforcement
* Support air-gapped or restricted environments, including image mirroring and upgrade strategies
* Perform Day-2 OpenShift operations:
o Logging, monitoring, GitOps, secrets management
o Cluster upgrades and life cycle management
* Work closely with security, infrastructure, and programme teams to ensure compliance and resilience
* Produce clear technical documentation and operational runbooks
Essential Skills & Experience
* Extensive hands-on Red Hat OpenShift experience (build, configure, operate)
* Strong knowledge of OpenShift security architecture, including:
o RBAC, SCCs, Network Policies
o Cluster hardening and compliance (CIS/STIG aligned)
* Solid Linux background (RHEL essential)
* Experience deploying OpenShift on on-prem platforms (eg vSphere)
* Strong Kubernetes fundamentals (but OpenShift expertise is mandatory)
Highly Desirable
* Experience in defence, financial services, or other regulated environments
* Air-gapped OpenShift deployments and upgrade experience
* Red Hat certifications (RHCA/OpenShift/Kubernetes Security)
* GitOps, CI/CD, and automation exposure (Ansible, Terraform, ArgoCD)
