Senior Java Engineer

Identifying and recruiting world class talent into CGI

At CGI, we’re shaping the future of digital government solutions—building secure, high‑impact platforms that improve services for millions across the UK. As a Senior Java Engineer, you’ll play a pivotal role in designing and developing scalable, resilient back‑end systems using the latest Java and microservices technologies. You’ll collaborate with skilled professionals who take ownership of their work, share ideas freely, and are empowered to create solutions that make a lasting difference.

This is an opportunity to contribute to a major national programme where innovation, teamwork, and continuous learning come together to deliver meaningful results.

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 we are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant.

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 role will be mainly remote with occasional travel as required to UK CGI or client offices.
