Position Description
At CGI, you will help engineer secure, resilient systems that underpin critical services and deliver real-world impact. As a Senior Java Engineer, you will play a key role within a collaborative delivery team, designing and building scalable solutions that support complex programmes. You will be trusted to take ownership of your work, encouraged to bring curiosity and creativity to technical challenges, and supported by a culture that values learning, shared success and continuous improvement. This is an opportunity to deepen your expertise, broaden your skillset and make a meaningful contribution within an organisation that empowers its engineers.
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 hold SC Clearance or be eligible to obtain it. This is a hybrid role, with an expectation of working 1–2 days per week on site in our Sheffield office, with flexibility for remote working for the rest of the time.
Your future duties and responsibilities
In this role, you will contribute to the design, development and maintenance of software systems within a modern engineering and DevOps environment. Working as part of a collaborative team, you will help build reliable, maintainable and scalable solutions across a microservices-based architecture, with a primary focus on Java while remaining open to working across the wider stack where needed.
You will collaborate closely with other engineers to review code, improve delivery practices and support deployment and operational processes.

* Improve team practices, tooling and delivery approaches
* Apply a pragmatic, problem‑solving mindset to engineering challenges
