Senior Service Designer

Job description

Position Description:

At CGI, we design and deliver services that make a meaningful difference to society. As a Senior Service Designer, you will shape end-to-end services that improve how people interact with critical public sector systems, ensuring they are accessible, effective, and built around real user needs. You will play a key role in influencing service direction, helping teams define the right problems to solve, and delivering outcomes that create lasting value. Working in a collaborative environment, you’ll have the opportunity to take ownership of complex challenges, apply creative thinking, and contribute to impactful solutions that support the transformation of public 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.

Working within multidisciplinary teams, you will collaborate closely with designers, researchers, product managers, and stakeholders to deliver cohesive, user-centred services.
You will take ownership of service design outputs, from journey maps to service blueprints, and use visual storytelling to communicate ideas clearly. You will guide teams through iterative design processes, facilitate co-creation, and drive continuous improvement by embedding feedback and insight into service evolution.
