Role purpose

The Change Manager leads the people and process side of change across Rimes, ensuring that new products, platform capabilities, and ways of working are adopted successfully within Operations, sustainably, and with minimal disruption to clients and colleagues.

The Change Manager works across product, engineering, data development, data operations, client services, Go To Market, across Rimes' global offices and time zones, to facilitate change from concept through to production and into BAU, making sure people are ready, trained and resourced, so adoption sticks.

• Ensure client facing and service teams are prepared to support clients through changes to the platform and services they rely on.
• Coordinate go-live activities, cutover planning, and hypercare support to stabilise adoption after launch.
