Chief Enterprise Architect

Across government, digital and technology transformation is no longer simply an enabling function; it is central to how public bodies deliver better services, protect resilience, support policy outcomes and respond to the growing expectations of citizens, businesses and colleagues. Ofgem has a vital role in the UKs energy system, protecting consumers and helping to enable a more secure, fair and sustainable energy future. As the organisation continues to evolve, our newly designed Digital, Data and Security Services (DDSS) team will be critical to how Ofgem modernises its services, strengthens its platforms and supports wider government priorities.

Ofgem is on an exciting transformational journey. Within DDSS, we are strengthening the foundations of our entire DDSS function and technology estate, building greater internal capability and creating the platforms, services and governance needed to support a modern regulator. In short, this is an opportunity to join Ofgem at a pivotal moment and help shape the next stage of its digital, data, security, and technology maturity.
