Head of Security Assurance

Requirements of the role

This is a rare full-time, permanent opportunity to take ownership of a nationally important cyber security function. You’ll shape how cyber risk is understood and managed across the organisation, guiding major programmes, engaging with senior leaders and government partners, and embedding security into everything we do. Your work will influence high-profile decisions, safeguard core services and help shape the UK’s wider regulatory resilience.

You’ll lead a committed, expert team that supports both current systems and future ambitions. Whether working with NCSC-aligned frameworks, steering architecture reviews or driving strategic risk conversations at board level, you’ll be at the centre of how we stay ahead of evolving threats, not just for today, but for the future.

We’re looking for a leader who brings credibility, clarity and confidence, someone who pairs technical depth with a sharp understanding of cyber risk, security architecture and assurance, and has the drive to influence, collaborate and deliver at pace.

Whether your experience comes from central government, national infrastructure, consultancy or a regulated private sector environment, you’ll have the ability to lead conversations at the highest levels and the expertise to shape how security supports Ofgem’s wider mission.

If you thrive on working across boundaries, influencing outcomes and setting direction at scale, this is your opportunity to make a difference where it truly matters.

As a key member of the Ofgem cyber leadership team, you’ll help us to continue building a flexible, hybrid working culture that focuses on inclusion, collaboration and trust. You’ll be supported by peers who value insight and impact and encouraged to lead with both purpose and perspective.

We have a critical mission to lead cyber security assurance across Ofgem’s operations, protecting the systems and services that support Britain’s transition to a fair, secure and low-carbon energy future.
