Position Description
At CGI, we partner with Defence clients to deliver critical data exploitation capabilities that strengthen national security and enable smarter, faster decision-making. As an Infrastructure Engineer, you will play a pivotal role in shaping and supporting secure, resilient platforms while guiding the migration of legacy services to MOD core cloud infrastructure. Working alongside senior client stakeholders, you will provide trusted technical insight, mitigate risk, and drive value across complex programmes. We empower you to take ownership of high-impact challenges, bring fresh thinking to complex problems, and collaborate within a supportive, expert-led environment where your contribution directly influences mission 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.
Your future duties and responsibilities
In this role, you will act as a trusted technical advisor within a client-side Defence environment, providing infrastructure expertise that ensures the successful delivery of secure, mission-critical capabilities. You will support legacy platforms while enabling their migration to MOD core cloud infrastructure, helping to reduce risk and improve long-term resilience. Working closely with project managers, architects, cyber security specialists and service delivery teams, you will bring clarity to complex technical challenges and ensure engineering coherence across Agile delivery teams.
