At CGI, we design and deliver secure, scalable digital solutions that transform how organisations operate and serve their customers. As a Full Stack Software Engineer, you will take ownership of building high-quality applications across the entire technology stack, shaping architecture decisions and delivering measurable outcomes for clients across the UK. Working in collaborative, multidisciplinary teams, you will apply modern engineering practices, embrace innovation, and continuously improve how we deliver software. With the freedom to explore new technologies — including the Microsoft Power Platform — and the support of a strong engineering community, you will play a key role in driving meaningful digital change.

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.

By taking ownership of quality, applying clean code principles, and embedding automated testing, you will help create resilient, maintainable systems that stand the test of time.

You will also contribute to technical design discussions, mentor junior engineers, and drive continuous improvement across the team. With the backing of a supportive engineering community, you will be empowered to experiment, strengthen best practice, and expand your expertise — including low-code delivery using the Microsoft Power Platform where appropriate.
