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 and has been named one of the ‘World’s Best Employers’ by Forbes magazine. 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 the highest level of UK Security Clearance or be eligible to go through this. This position will be working out of client sites near Cheltenham.

Your future duties and responsibilities:

Are you a Linux expert with a passion for automation and next-gen infrastructure? We’re looking for a skilled Linux Infrastructure Engineer to help architect, deploy, and maintain robust, scalable systems that power high-availability services across our organisation.

In this role, you’ll play a critical part in transforming how we deliver infrastructure—applying automation, containerisation, and infrastructure-as-code (IaC) to streamline operations and drive performance. You’ll work at the heart of our infrastructure strategy, enabling data-driven decisions and resilient platform delivery.

What You’ll Be Doing:

• Designing and implementing scalable, secure Linux-based infrastructure.

• Driving automation and efficiency through tools like Ansible, Terraform, and CI/CD pipelines.

• Supporting containerised environments and modern DevOps practices.

• Monitoring, optimising, and enhancing system performance using data insights and analytics.

Required qualifications to be successful in this role:

• Proven expertise in Linux system engineering, with hands-on experience in complex infrastructure environments.

• A strong foundation in automation, scripting, and IaC methodologies.

• Familiarity with containers (Docker, Kubernetes) and supporting tools.

• A mindset geared toward resilience, scalability, and continuous improvement.
