As a Data Engineer, you’ll contribute to a modern, large-scale data platform, building reliable and scalable pipelines that enable trusted insight and better decision-making. Working within a collaborative delivery environment, you’ll apply strong engineering practices, take ownership of your solutions, and continuously improve how data is designed, processed, and consumed. You’ll be supported to develop your skills, share ideas, and grow your career while delivering work that makes a real difference.

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.
