Full job description

At CGI, we’re shaping the digital future by delivering secure, resilient, and innovative technology solutions that help our clients achieve operational excellence. As an Infrastructure Engineer, you will play a key role in designing, building, and supporting cloud and on-premise environments that power mission-critical services. Working alongside industry experts, clients, and technology partners, you will help solve complex infrastructure challenges, contribute innovative ideas, and build a rewarding career within a collaborative environment where your expertise is valued, your development is supported, and your work makes a real difference.

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. This is your opportunity to be part of something challenging, meaningful, and career-defining.

You will need to hold UK Security Clearance or be eligible to go through this clearance. This position will be based on site 5 days a week.

Your future duties and responsibilities

In this role, you will design, build, and support infrastructure solutions across cloud and on-premise environments, ensuring systems meet demanding performance, security, and availability requirements. You'll take ownership of infrastructure across compute, storage, networking, and virtualisation technologies, supporting both project delivery and live operational services within complex, mission-critical environments.

Working closely with CGI colleagues, clients, and technology partners, you will deliver resilient, scalable solutions while contributing innovative approaches to infrastructure engineering. You'll be encouraged to continuously develop your technical expertise, share knowledge with others, and play an active role in delivering successful outcomes for our clients.

Design & Deliver secure infrastructure solutions across cloud and on-premise environments
Deploy & Configure compute, storage, networking, and virtualisation platforms
Integrate & Support cloud technologies, including Oracle Cloud Infrastructure where applicable
Monitor & Optimise infrastructure performance, availability, capacity, and resilience
Troubleshoot & Resolve complex infrastructure incidents and technical issues
Collaborate & Deliver with cross-functional teams, clients, and technology partners
Automate & Improve operational processes through scripting and infrastructure automation where appropriate
Communicate & Report technical progress, risks, and system health to stakeholders

Required qualifications to be successful in this role

To succeed in this role, you should have proven experience delivering and supporting enterprise infrastructure within complex environments. You will bring strong systems administration skills, a solid understanding of networking and virtualisation technologies, and experience working with cloud platforms. A proactive approach to problem-solving, collaboration, and continuous improvement will help you thrive as part of CGI's expert engineering teams.

Proven experience as an Infrastructure Engineer within enterprise or secure environments
Strong systems administration experience across Windows and/or Linux platforms
Solid understanding of networking fundamentals, including TCP/IP, DNS, routing, and firewalls
Experience with cloud infrastructure platforms, ideally Oracle Cloud Infrastructure (OCI)
Experience with virtualisation technologies such as VMware or Hyper-V
Proven troubleshooting, root cause analysis, and incident resolution skills
Experience with container technologies and image management (desirable)
Knowledge of automation, scripting (e.g. PowerShell, Bash, Python), or Infrastructure as Code (advantageous)
Ability to work within secure environments and obtain or hold UK Security Clearance

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.

That same commitment to fairness extends to how we use technology. To support our recruitment team, AI tools may be used to help assess applications though they never replace human judgement. All hiring decisions remain entirely in the hands of our recruitment professionals.

Come join our team—one of the largest IT and business consulting services firms in the world.
