DevOps Engineers

CGI was recognised in the Sunday Times Best Places to Work List 2025 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 member 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. CGI’s Space, Defence and Intelligence business unit focuses primarily on the delivery of contemporary and innovative technical solutions for the government agencies' most challenging problems. We work, build, and operate bespoke, technically complex, mission-critical systems which help our clients keep us all safe and secure.

We are currently looking for an experienced DevOps engineer to join our cross-functional team who, in partnership with our clients, will help define, guide and assure the delivery of integrated solutions. The role offers fantastic opportunities to work within an interesting and highly rewarding environment. We are heavily committed to developing our members and provide excellent learning and development opportunities to ensure that your knowledge and skills keep pace with the evolving technology landscape. We engender a culture of innovation, collaboration and ownership; highly motivated self-starters thrive within our organisation.

Although we would like candidates to have all the skills we need, we would consider high quality individuals who meet most of the criteria. Due to the secure nature of this project, this role requires candidates to either already hold, or be eligible to obtain, a high level of UK Security Clearance. To meet the eligibility criteria for this clearance, applicants must be sole British nationals, have been resident in the UK for the past 10 years, and must not have spent more than 28 consecutive days outside the UK within the last five years. Individuals who do not currently hold clearance are still encouraged to apply and will be considered both for this position and for other suitable opportunities within CGI where appropriate.

This role is primarily based on a secure client site and requires attendance on site five days per week due to the sensitive nature of the work and the systems involved. While the position is predominantly site-based, there may be occasional flexibility where business needs and security constraints allow. Any such arrangements would be agreed in advance with the project team.

Candidate Profile

We are looking for a highly skilled, proactive, and mission-driven DevOps Engineer to join our dynamic team. In this role, you will apply your expertise in engineering, automation, and DevOps practices to build and maintain systems that play a vital role in keeping the country safe. You will help design and deliver robust, scalable, and secure platforms, ensuring our clients can operate with confidence in high-stakes environments. You will work across a diverse technology landscape, collaborating closely with developers, testers, and platform specialists to diagnose and resolve complex technical challenges. This will include recreating tests, validating configurations, enhancing pipelines, and where possible automating key elements of the software development lifecycle to drive efficiency and reliability. Your role will also involve ensuring the quality assurance of applications and their deployment into traditional IaC-driven environments such as Puppet-managed infrastructure and Kubernetes platforms. You will be an active participant in Kanban and/or Scrum events, helping to plan, estimate, and prioritise work as part of a high-performing cross-functional team.

Required Qualifications To Be Successful In This Role

• Kubernetes
• Argo
• Rancher
• Cloud Experience
• Linux administration
• Experience with Puppet or similar Infrastructure-as-Code tooling
• Scripting languages including Python, Java and Bash
• Working with Git/SVN source control systems

We don’t expect candidates to know everything on the list. Experience across multiple areas is desirable, the ability to learn quickly, and a willingness to contribute across the technology stack as required.
