Position Description:
At CGI, we design and run critical systems that keep the UK moving. As a Technical Architect within one of our key UK Government programmes, you’ll play a vital role in strengthening the stability, performance and resilience of complex, large-scale platforms. You’ll work at the heart of live services, shaping technical outcomes, resolving high-impact issues and proactively improving environments that matter. We empower our people to take ownership, think creatively and collaborate closely with experts across disciplines, giving you the support and autonomy to make meaningful, lasting impact while helping our clients and services perform at their best.
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 is a hybrid position with some occasional expensed travel to London and Bridgend for team/client meetings
Your future duties and responsibilities:
In this role, you will provide technical leadership across live services, taking ownership of complex incidents, performance challenges and service improvements within a large-scale application and infrastructure environment. You’ll collaborate closely with subject matter experts, problem management and technical leadership to investigate root causes, improve system resilience and ensure services continue to operate reliably.
You will also proactively identify risks and improvement opportunities, contribute to architectural thinking, and support wider initiatives such as BCDR planning and design assurance. Working in an Agile environment, you’ll balance deep technical analysis with clear communication, helping both technical and non-technical stakeholders understand issues and outcomes while being supported by a collaborative, expert-led culture.

• Contribute to service improvement initiatives and preventative technical reviews
• Support BCDR planning and provide architectural oversight where required
• Review and validate technical documentation and designs
• Engage in regular technical and operational forums to share insight and drive alignment
Required qualifications to be successful in this role:
You will bring broad technical architecture experience gained within complex, enterprise-scale environments, along with a proactive mindset and strong communication skills. You’re comfortable troubleshooting live services, working across infrastructure and applications, and continuously learning new technologies to improve outcomes.

• Strong experience as a Technical or Solutions Architect in large-scale environments
• Solid knowledge of Windows Server, Active Directory and Linux platforms
• Good understanding of networking concepts including routing, firewalls, protocols and load balancing
• Experience with containerised services such as Docker
