Job Description

At CGI, you'll play a pivotal role in guiding clients through high-impact transitions that shape the future of their organisations. As a Transition Manager, you will lead complex, business-critical programmes that deliver measurable outcomes, strengthen client partnerships, and enable innovation across diverse sectors.
