Job Summary This is an exciting time for policy work in the energy sector, with rapid change creating new opportunities to shape how data supports fair, effective and future‑focused markets. As Head of
Data Transformation, you will play a pivotal role in helping Markets teams respond to these changes through business‑focused data transformation rather than technical delivery.
Sitting within the Markets Data Management Office, you will lead a portfolio of transformation initiatives that improve data maturity, quality and accessibility across policy, analysis and operational teams. Your focus will be on understanding business needs, prioritising the right initiatives, and ensuring data services are designed, delivered and adopted to support real‑world decision‑making and regulatory outcomes. This role is about translating complex business challenges into practical, achievable data improvements that deliver measurable benefits.
You will provide leadership to a multidisciplinary team, embedding strong portfolio management, governance and change practices, while working closely with senior stakeholders across Markets. With accountability for the data transformation roadmap, benefits realisation and stakeholder engagement, you will help ensure data becomes a strategic enabler of policy and market outcomes.
This is a high‑impact leadership role for someone who thrives on business‑focussed change, influencing at senior levels and delivering lasting improvements through data.
