Full job description

The Space, Defence and Intelligence business unit in CGI is a true IT Systems Integrator. We work, build, and operate bespoke, technically complex, mission-critical systems which help our clients keep us all safe and secure. We bring innovation to our clients using proven and emerging technologies, agile delivery processes and our deep expertise across the breadth of space, defence, intelligence, aerospace and maritime, all underpinned by our end-to-end cyber capability. We work collaboratively with global technology companies, cutting edge SMEs and academia to deliver the optimal solution for each client.

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 on site near Chippenham 5 days a week.

Your future duties and responsibilities

In this role, you will design end-to-end network architecture aligned with system and infrastructure requirements, ensuring solutions are scalable, secure, and optimised for performance across cloud and on-premises environments. You will define standards, patterns, and best practices while guiding implementation to ensure alignment with architectural intent.
You will work closely with engineering and delivery teams to support build and integration activities, ensuring network components are deployed effectively within the wider infrastructure. You will also optimise network performance, address capacity and latency challenges, and embed security-by-design principles, contributing to governance, documentation, and technical assurance.

Required qualifications to be successful in this role
