Full job description

At CGI, you will help design and deliver secure, resilient network solutions that support mission-critical systems across the Space, Defence and Intelligence sector. As a Network Engineer, you will play a key role in enabling high-performance connectivity across complex environments, ensuring systems remain robust, secure and fit for purpose. Working with leading technologies and expert teams, you will take ownership of network challenges, contribute innovative solutions, and grow your capabilities within a collaborative and supportive environment.

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 Gloucester or in Central London 5 days a week.

Your future duties and responsibilities

In this role, you will design, implement and support secure network infrastructure across cloud and on-premise environments, ensuring high levels of performance, resilience and security. You will take ownership of network components including routing, switching and security, contributing to both project delivery and operational support within complex, secure environments.

Working closely with engineering teams and Oracle partners, you will help deliver scalable and reliable connectivity solutions, applying innovative approaches to network engineering while being supported by experienced colleagues and a collaborative culture.

Together, as owners, let’s turn meaningful insights into action.

Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you’ll reach your full potential because…

You are invited to be an owner from day 1 as we work together to bring our Dream to life. That’s why we call ourselves CGI Partners rather than employees. We benefit from our collective success and actively shape our company’s strategy and direction.

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.
