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.
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.
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.
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.
