Senior Portfolio Performance Manager

Available in either of our 3 office locations: London, Glasgow, and Cardiff

Ofgem's mission is to protect energy consumers and deliver Net Zero. We are looking for a Senior Portfolio & Performance Manager to play a vital role in driving the strategic oversight and assurance of our diverse portfolio of programmes and projects. We need a passionate leader to join our Enterprise Portfolio Management Office (ePMO) and establish and maintain robust assurance processes that ensure alignment with our strategic priorities and deliver meaningful outcomes.

Ofgem is Great Britain's independent energy regulator. We're at the forefront of change across the energy sector, driving towards Net Zero whilst protecting energy consumers - especially vulnerable people.

We're offering a permanent role with the opportunity to directly influence the delivery of our Forward Work Plan and Multi-Year Strategy. This role combines strategic leadership, portfolio assurance, and stakeholder engagement to help shape the future of energy regulation in the UK. You'll contribute to high-impact programmes that enable investment in low-carbon infrastructure, promote data-driven energy solutions, and safeguard consumer interests.

You'll be part of a high-performing team within a collaborative environment that values continuous improvement and operational excellence. With an emphasis on professional growth and inclusivity, we offer a workplace where you will be empowered to implement your ideas and make real change for the future.

We're looking for someone with expertise in corporate planning, portfolio management, and assurance, alongside a track record of implementing and leading change collaboratively. You'll have the ability to navigate complex tasks, engage effectively with stakeholders, and embed a culture of continuous improvement. A relevant qualification in portfolio management or project assurance (e.g., MSP, PRINCE2, or APM) is essential.

This role comes with excellent benefits, including flexible working arrangements, a strong focus on learning and development, and the chance to work alongside peers and talented industry professionals in our newly refurbished offices in central Glasgow, London, or Cardiff.

We have a critical purpose to drive a culture of portfolio excellence and deliver impactful, future-focused assurance that supports the energy sector's journey to Net Zero. This is a high-profile opportunity to shape the future of energy regulation while safeguarding consumers and enabling transformative change.
