At CGI, you’ll play a key role in strengthening the digital backbone of mission-critical defence programmes. As an Infrastructure Support Engineer, you will help ensure the reliability, security, and performance of the platforms that keep our clients’ operations moving. You’ll work with cutting-edge technologies, apply your expertise to solve complex challenges, and contribute to solutions that make a real impact. Here, you’ll be trusted to take ownership, supported by a community of experts, and encouraged to explore new ways of delivering resilient, high-value infrastructure for the future.

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.

Candidate profile

In this role, you will deliver hands-on support for critical infrastructure used across a major defence programme, ensuring systems remain stable, secure, and resilient. You will work closely with senior engineers, contributing to improvements, resolving incidents, and shaping the evolution of the platform. You’ll be empowered to take ownership of problems, apply creative thinking to technical challenges, and work within a supportive team to deliver high-quality outcomes.

You will maintain core infrastructure technologies, troubleshoot complex issues, and support an on-call rota to ensure business-critical services are available around the clock. Your work will directly contribute to platform reliability, security assurance, and operational success.

Key responsibilities:

Support & Troubleshoot: Provide technical support across VMware Cloud Foundation, Tanzu, VxRail, Data Domain, and key management systems.

Secure & Manage: Support privileged access and identity systems, including BeyondTrust and KeyCloak.

Administer & Maintain: Manage Windows Server environments, Hyper-V, and routine system upkeep.

Monitor & Improve: Track performance, contribute to continuity planning, and enhance infrastructure resilience.

Collaborate & Document: Work with senior engineers and keep documentation current and comprehensive.

Respond & Resolve: Participate in an on-call rota to address critical incidents effectively.

Required qualifications to be successful in this role

To succeed, you should bring hands-on experience in infrastructure or support engineering, ideally within a defence environment. You’ll need a solid foundation across core infrastructure technologies, strong communication skills, and a willingness to develop your expertise further through training and certification.

Essential qualifications:

Experience working in Defence environments.

Proven background in infrastructure or support engineering.

Knowledge of VMware, Microsoft, or security technologies (certifications or willingness to work toward them).

Strong teamwork, communication, and problem-solving abilities.

Desired:
