Full job description

At CGI, we deliver secure, resilient infrastructure solutions that underpin critical national programmes. As an Infrastructure Engineer, you will take ownership of complex network, storage, and server environments that enable high-impact outcomes for our defence clients. We design and manage robust, secure architectures that drive operational excellence and long-term resilience. Joining CGI means shaping secure digital foundations, applying innovative thinking to complex challenges, and collaborating with trusted experts in a culture that values accountability, growth, and continuous improvement.

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 must hold Higher Level Clearance and be willing to undergo further clearance. This is a hybrid position based in Leatherhead, with 3–4 days per week onsite.

Your future duties and responsibilities

In this role, you will take full engineering ownership of secure infrastructure environments, designing, implementing, and maintaining network, storage, and Windows Server platforms that support critical defence operations. You will manage your own workload under project guidance, ensuring solutions are delivered to the highest standards of performance, resilience, and security.

You will proactively monitor and optimise infrastructure, resolve complex technical issues, and drive continuous improvement across network and storage systems. Working closely with stakeholders, you will ensure compliance with security policies while delivering robust, scalable solutions that safeguard data integrity and availability.

> Design & Implement complex LAN, WAN, and cloud-based network architectures

> Configure & Secure firewalls, routers, switches, VPNs, and access controls

> Monitor & Optimise network performance, availability, and security

> Manage & Maintain SAN, NAS, backup, and disaster recovery solutions

> Administer & Support Windows Server environments, including AD, DNS, DHCP, and Group Policy

> Protect & Govern data through patch management, updates, and security compliance

Required qualifications to be successful in this role

To succeed, you will bring strong hands-on experience across secure network, storage, and Windows Server environments within defence or highly regulated settings. You will demonstrate the ability to take technical ownership, manage competing priorities, and deliver resilient infrastructure solutions aligned to strict security standards.

> You must hold Higher Level Clearance and be willing to undergo HLC

> Proven experience designing and managing LAN, WAN, and secure network architectures

> Strong expertise in firewalls, routers, switches, VPNs, and network security

> Hands-on experience with SAN, NAS, backup, and disaster recovery solutions

> Strong Windows Server administration skills (Active Directory, DNS, DHCP, Group Policy)

> Experience with patch management, system upgrades, and access control governance

> Ability to manage workload independently while collaborating effectively with stakeholders
