Shape the future of the UK electricity market
Elexon is a purpose-driven, not-for-profit organisation operating at the heart of Great Britain's wholesale electricity market. We play a critical role in enabling a secure, flexible, net-zero energy system — working across industry, government and consumers to deliver market confidence and nationally significant change.
This is a defining moment to join Elexon. We have successfully delivered market-wide Half-Hourly Settlement, transforming how electricity is balanced and settled and unlocking investment in low-carbon generation. We are now leading the development of local flexibility markets through the Flexibility Market Asset Registration (FMAR) service, creating a single enduring register for flexible assets ahead of live operation in late 2025. From mid-2026, Elexon will also provide enduring governance for the Government's Smart Secure Electricity Systems (SSES) programme, reinforcing our position at the centre of electricity market reform.
The opportunity
We currently have an exciting opportunity for a Chief Markets Officer (CMO) to join our Executive team and lead the Markets function, ensuring that Elexon's market frameworks, codes, and operational arrangements remain efficient, fair, and effective in delivering an affordable, clean and secure energy system.
CMO will focus on market design, governance, rules and compliance, helping ensure the markets we support are robust, accessible and fit for the future.
You will act as principal liaison for Ofgem, Department of Energy Security and Net Zero (DESNZ), National Energy System Operator (NESO), Distribution System Operators (DSOs), wider industry bodies, spanning market effectiveness, evolutionary design, operational performance, regulatory compliance.
