At CGI, we are driving critical transformation programme for our Space, Defence, and Intelligence business unit, delivering secure, high-impact solutions that enable mission success. We are seeking a Service Transition Manager to lead the seamless integration of capabilities into a next-generation Identity and Access Management service. In this role, you will shape service readiness, ensure operational continuity, and deliver measurable outcomes within a complex, security-cleared environment. Working collaboratively with experts across CGI and our clients, you will take ownership of transition delivery, contribute innovative approaches, and play a key role in advancing secure digital services that make a real-world 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.



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 is a hybrid position with frequent onsite commitments in Chippenham.

You will take ownership of planning, governance, and execution, ensuring all activities align with service readiness criteria and Defence assurance standards. Working across multiple stakeholders, you will drive collaboration, maintain control of risks and dependencies, and ensure knowledge is effectively transferred to enable a stable and successful transition into live service.



You will also oversee Early Life Support and guide services into Business-as-Usual operations, ensuring performance, resilience, and continuous improvement. By bringing structure, clarity, and innovation to the transition lifecycle, you will play a key role in delivering secure, scalable outcomes for critical national programmes.
