You’ll work at the heart of a multidisciplinary team, collaborating with internal stakeholders and leading national security partners to embed robust security into every stage of the digital lifecycle. As a recognised expert, you’ll play a central role in building long-term cyber strategies and providing guidance that sets standards across our organisation and the wider energy ecosystem.

We’re looking for someone with a deep understanding of security architecture and a proven track record of influencing complex programmes and senior leaders. Your approach to solving challenges will be methodical and strategic, and you’ll be comfortable operating in fast-paced, high-stakes environments where your guidance truly matters.

In return, you’ll join a collaborative and inclusive culture that values innovation and supports development. You’ll benefit from flexible working arrangements, excellent civil service benefits, and the opportunity to be part of a high-profile mission that impacts millions of people and the UK’s energy future.
