(SC cleared) Senior OpenShift Platform Engineer

We are seeking an experienced Senior OpenShift Platform Engineer to support and modernise enterprise container platforms hosting business-critical applications within a secure defence environment.

This is a hands-on engineering role focused on OpenShift platform support, container management, deployment automation, runtime engineering, vulnerability remediation, monitoring, operational resilience and technical troubleshooting.

The successful candidate will work closely with client and supplier teams to assess existing environments, resolve technical issues, improve operational stability and support future platform evolution.
