Full job 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.

You will take ownership of technical assurance activities, working with the client assurance lead to manage JSP 453 controls and support DEAB approvals, including achieving the appropriate authority to process. By collaborating with solution suppliers and senior stakeholders, you will drive value for money, unblock delivery challenges, and contribute to PI Planning to align infrastructure outcomes with programme objectives.

Provide & Advise: Deliver expert technical insight to client stakeholders across infrastructure, cloud migration and legacy support

Mitigate & Assure: Identify and resolve technical risks, leading JSP 453 control activities to support approvals and accreditation

Collaborate & Align: Work with architects, Scrum Masters and suppliers to ensure engineering coherence across Agile teams

Enable & Migrate: Support transition from legacy platforms to MOD core cloud infrastructure

Engage & Influence: Contribute to PI Planning and proactively engage stakeholders to drive successful delivery

Required qualifications to be successful in this role

To succeed, you will bring strong infrastructure engineering experience within secure or Defence environments, combined with proven consultancy skills and the ability to engage confidently with senior stakeholders. You will be comfortable navigating complex governance frameworks, supporting assurance processes, and influencing multidisciplinary teams to achieve shared outcomes.

You should have strong experience in infrastructure engineering, ideally within MOD or secure government environments

Proven knowledge of cloud migration and legacy platform support

Experience working with assurance frameworks such as JSP 453 and supporting ATO/AtT/iATO processes

Excellent verbal and written communication skills

Demonstrated ability in conflict resolution and stakeholder management

Strong team collaboration skills across technical and non-technical audiences

Proactive engagement style with multiple stakeholders

DV clearance (preferred) or willingness to undergo high-level clearance; must be a sole UK national and passport holder
