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 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 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.

Candidate profile

In this role, you will design, develop, and maintain secure, high-performing Java applications that underpin key public services. Working collaboratively within a cross-functional team, you’ll help shape modern architectures using microservices and cloud-native technologies to deliver scalable, maintainable systems. You’ll contribute to all stages of the development lifecycle, from technical design and implementation through to testing and optimisation.

You will be encouraged to take ownership of your work, bring forward creative ideas, and leverage the support of a highly experienced team that values collaboration and continuous improvement.

Key responsibilities include:

- Design and Develop: Build and enhance Java-based microservices using Spring Boot and related frameworks

- Collaborate and Deliver: Work closely with developers, architects, and testers to ensure technical excellence and timely delivery

- Optimise and Innovate: Improve performance, scalability, and maintainability of systems through continuous iteration

- Contribute and Support: Participate in agile ceremonies, share knowledge, and support a culture of quality and innovation

- Secure and Maintain: Ensure all solutions meet strict security and compliance requirements

Required qualifications to be successful in this role

You should have experience developing large-scale enterprise applications using Java and microservices frameworks, alongside a solid understanding of secure, scalable system design. You’ll bring an analytical mindset, collaborative approach and a drive to deliver high-quality code that meets user and business needs.

Required experience:

- Proven experience as a Java Developer or Senior Software Engineer

- Strong proficiency in Java, Spring Boot, and RESTful API development

- Experience with microservices architecture and containerisation (e.g., Docker, Kubernetes)

- Familiarity with Agile/Scrum methodologies and CI/CD pipelines

- Understanding of cloud environments (AWS/Azure/GCP) and DevOps principles
