About the job

Job summary

Across government, the effective delivery of IT services is essential to enabling organisations to operate efficiently, securely and responsively. As digital services become more integral to core operations, strong service management capability is critical to ensuring reliability, performance and continuous improvement. Ofgem plays a vital role in the UK’s energy system, protecting consumers and enabling a more secure, fair and sustainable energy future, and high-quality IT services are fundamental to supporting this mission.

Ofgem is on an ambitious transformation journey. Within the Digital, Data and Security Services (DDSS) directorate, we are modernising our technology estate while maintaining reliable day-to-day services. This requires strong service leadership to ensure that both operational (‘run’) services and transformation (‘change’) initiatives deliver value to users, meet service standards and align with organisational priorities.

As a Senior IT Service Manager, you will be accountable for the delivery and continuous improvement of a portfolio of IT services. You will set service strategy, oversee performance and act as a senior escalation point for complex issues. You will also lead supplier relationships, ensuring services are delivered effectively across a multi-sourced environment and that service quality meets both user expectations and organisational standards.

This is a senior service management role with significant responsibility across service management, stakeholder engagement and operational delivery. You will combine strategic oversight with hands-on service governance, driving improvements and ensuring high-quality service outcomes.

Job description

You will be responsible for:

• Leading the development of the end-to-end delivery of IT services, ensuring alignment with organisational objectives and adherence to ITIL-based practices while reporting into the Head of Service Management
• Owning service performance, monitoring SLAs and driving improvements to ensure high levels of reliability, availability and user satisfaction.
• Acting as the service management authority for assigned services, ensuring governance, accountability and operational excellence.
• Serving as the senior escalation point for complex or critical service issues, ensuring timely resolution and effective stakeholder communication.
• Leading supplier and vendor relationships, holding partners accountable for performance and ensuring alignment with contractual and service expectations.
• Chairing service review meetings and governance forums, providing clear reporting and insight into service performance.
• Driving continual service improvement initiatives, identifying opportunities to enhance efficiency, resilience and value delivery.
• Maintaining service documentation, including service catalogues and knowledge bases, ensuring they are accurate and accessible.
• Supporting financial management of services, including cost control, forecasting and optimisation activities.
• Building and supporting high-performing teams, providing coaching and mentorship to develop capability across service management functions.
• Supporting the delivery and transition of new services into live operation, ensuring operational readiness and sustainability.

We are looking for:

An experienced and well-rounded IT service management professional who can lead a portfolio of services in a complex, multi-supplier environment. You will bring strong leadership capability, alongside deep knowledge of service management frameworks and practices.

You may come from a service management, IT operations or delivery background, but you will demonstrate:

• Significant experience owning and managing IT services within an enterprise environment
• Strong knowledge of ITIL frameworks and service management best practice
• Experience managing supplier relationships and holding vendors accountable for performance
• Proven ability to drive service improvement and enhance operational performance
• Strong stakeholder engagement skills, with the ability to influence across technical and business domains

An ITIL v4 Foundation certification is required, with higher-level ITIL certifications (e.g. Create, Deliver and Support) strongly preferred.

Experience operating within government or regulated environments, and in service transition or transformation activities, would be beneficial.

This is an opportunity to play a key role in shaping how Ofgem delivers IT services. You will ensure that services are reliable, efficient and aligned with user needs, supporting both operational excellence and successful delivery of organisational transformation.
