At CGI, our Space, Defence and Intelligence business unit delivers mission‑critical systems that help keep the UK safe and secure.
As an OpenShift Infrastructure Engineer, you will play a key role in designing, building, and operating containerised platforms that enable scalable, resilient, and secure solutions. Working on complex, high‑impact programmes, you will help drive innovation through cloud‑native technologies and automation. You’ll take ownership of platform engineering activities, contribute creative solutions to technical challenges, and collaborate within a supportive environment that enables continuous growth and meaningful impact.
We offer a competitive salary, excellent pension, private healthcare, and a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner, not just an employee.
Due to the secure nature of the programme, you will need to hold UK Security Clearance or be eligible to go through this clearance. This position will be based on site near Gloucester 5 days a week.
