* Collaborate with product, platform, and supplier teams to review and assure support requirements.
* Develop and maintain service support documentation including policies, processes, and procedures.
* Ensure consistency and alignment between support models and existing service architecture.
* Support production of capacity, capability, and resource models required for ongoing service operation.
* Review SLAs, support models, knowledge transfer, and reporting frameworks to ensure contract and performance alignment.
* Capture and manage service dependencies and ensure all transition activities are coordinated effectively.
* Provide clear management reporting, service metrics, and performance insights to programme leadership.
Experience & Skills Required
* Demonstrable experience delivering Service Design and Transition within large, complex, multi-supplier programmes.
* Deep understanding of ITIL frameworks (V3/V4) and practical experience embedding service management processes.
* Strong background in designing and implementing service architectures for enterprise or public‑sector systems.
* Proven ability to influence and build relationships across technical, commercial, and operational teams.
* Solid understanding of cloud‑based and hybrid environments, configuration management, automation, and deployment tooling.
* Experience working within Agile delivery environments and multi‑disciplinary teams.
* Track record of transitioning services throughout the full lifecycle — from design through to BAU.

* Project management qualification (e.g. PRINCE2, MSP, or equivalent)
