At CGI, you'll help shape the future of cyber defence by engineering the modern platforms. This role gives you the opportunity to build cloud‑native, containerised solutions that strengthen national security while driving meaningful technical innovation. You'll work at the heart of a collaborative engineering community, enhancing reliability, scalability, and automation across complex environments. Here, you can take real ownership of high‑impact solutions, bring creative thinking to modern delivery practices, and grow your career with the support of experienced technologists who value curiosity, initiative, and shared success.

CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named a UK "Best Employer" by the Financial Times. We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces, and are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant. Join us and you'll be part of an open, friendly community of experts. We'll train and support you in taking your career wherever you want it to go.

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 is a hybrid position.

In this role, you will design, build, and operate modern Linux‑based, containerised platforms that underpin advanced cyber‑defence capability. You'll engineer Kubernetes‑driven solutions, enhance automation across development and deployment workflows, and work collaboratively with multidisciplinary teams to deliver resilient, scalable systems. You'll take ownership of platform performance, apply creative problem‑solving to drive continuous improvement, and be supported by a highly skilled community as you develop new approaches to cloud‑native engineering.

You’ll also contribute to the integration, configuration, and testing of systems, translating detailed business and technical requirements into robust software and platform functionality. As systems evolve, you'll help shape their lifecycle management, ensuring operational excellence across complex, mission‑critical environments.
