Job Description

At CGI, we help clients modernise and enhance critical digital services that support millions of users and deliver meaningful outcomes. As an Application Architect, you'll play a key role in shaping the future of complex enterprise applications, influencing architectural decisions, and driving technology improvements that increase stability, performance, and scalability. Working across Agile delivery teams, operational support functions, and senior stakeholders, you'll help translate business needs into robust technical solutions while guiding the evolution of both existing and emerging platforms. Joining CGI means becoming part of a collaborative environment where your expertise is valued, your ideas help shape strategic direction, and your contributions have a lasting impact on mission critical services.

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 currently hold UK Security Clearance and be willing to undergo additional clearance as part of onboarding. This is a hybrid position.
