Job summary

Across government, cloud technology underpins the delivery of secure, scalable and modern digital services. As organisations adopt cloud-first strategies, strong architecture is essential to ensure platforms are well-designed, governed and able to deliver long-term value. Ofgem plays a vital role in the UK’s energy system, protecting consumers and enabling a more secure, fair and sustainable energy future, and a robust Architecture capability is central to this mission.
