Full job description

At CGI, you will play a pivotal role in delivering secure, scalable infrastructure solutions that underpin critical operations across the Space, Defence and Intelligence sectors. Working at the forefront of innovation, you will design, build and manage modern enterprise environments that enable mission success and drive measurable outcomes for our clients. You will contribute to high-impact programmes, shaping resilient platforms while collaborating with experts in a culture that values accountability, technical creativity, and continuous development.

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 position will be based in the CGI Chippenham office 5 days a week.

Your future duties and responsibilities

In this role, you will design, build and manage secure, high-performing infrastructure environments that support critical defence and intelligence operations. You will take ownership of delivering robust platforms across virtualised, cloud and software-defined environments, contributing to solution design and influencing key technical decisions. Working closely with architecture, security and delivery teams, you will help shape resilient systems while continuously identifying opportunities to optimise, modernise and automate infrastructure services.

You will play a key role in ensuring systems are reliable, scalable and aligned with strict security requirements, while also supporting complex troubleshooting and ongoing improvements. Your contributions will directly impact programme success, enabling innovative solutions in highly secure environments while being supported by a collaborative and forward-thinking team.

Build & Configure: Develop enterprise infrastructure environments across virtualised and cloud platforms

Deploy & Optimise: Implement and enhance VMware, VxRail and NSX-based solutions

Operate & Maintain: Manage day-to-day infrastructure operations, ensuring performance and availability

Architect & Secure: Design network and cross-domain solutions aligned to security standards

Support & Resolve: Provide 2nd/3rd line support and resolve complex infrastructure issues

Collaborate & Deliver: Work with cross-functional teams to deliver high-quality, timely solutions

Automate & Improve: Identify optimisation opportunities and contribute to automation initiatives

Required qualifications to be successful in this role

You will bring strong experience in enterprise infrastructure engineering within defence or secure environments, with a focus on virtualisation, cloud technologies and secure system design. A solid understanding of infrastructure lifecycle management, combined with hands-on technical expertise, will enable you to contribute effectively to complex, high-impact programmes.

Proven experience working in Defence or secure environments

Strong knowledge of enterprise infrastructure (compute, storage, networking)

Hands-on experience with VMware technologies (including Cloud Foundation, VxRail)

Experience designing or supporting cross-domain solutions

Understanding of infrastructure lifecycle management and best practices

Experience implementing and managing SSO solutions

Experience with Kubernetes platforms, ideally VKS

Familiarity with security standards, processes and policies in Defence (desirable)

Exposure to automation tools and Infrastructure as Code (desirable)

Knowledge of hybrid or multi-cloud environments (desirable)

Strong Linux and/or Windows Server administration skills (desirable)

Your work creates value. You’ll develop innovative solutions and build relationships with teammates and clients while accessing global capabilities to scale your ideas, embrace new opportunities, and benefit from expansive industry and technology expertise.

You’ll shape your career by joining a company built to grow and last. You’ll be supported by leaders who care about your health and well-being and provide you with opportunities to deepen your skills and broaden your horizons.
