Shape how Britain understands nuclear safety. How do you explain complex, safety‑critical work to millions of people in a way that’s clear, engaging and trusted? At the Office for Nuclear Regulation (ONR), that challenge sits at the heart of what we do – and we’re looking for a Communications and Social Media Manager to lead the way. This is a rare opportunity to take genuine ownership of an organisation’s social media channel and help shape how the public understands nuclear safety and security regulation in the UK.

From operating sites and decommissioning facilities to new nuclear projects, you’ll be telling the stories behind some of the most important – and scrutinised – work in the country.

The role:

• As ONR’s social media lead, you’ll set the direction for our presence online.
• You’ll develop and deliver our social media strategy, create compelling content across platforms, and grow our reach by bringing fresh thinking and digital innovation into everything we do.
• This is a hands‑on role: you’ll be writing, filming, producing and publishing content that makes complex regulatory work accessible and interesting.
• Working closely with inspectors and colleagues across the organisation, you’ll uncover stories from behind the scenes and provide expert communications advice.
• You’ll also use data and insight to understand what works and keep improving our digital performance.

This role sits within a supportive, multi‑disciplinary Communications team, giving you exposure to media, campaigns, events and internal communications, alongside plenty of opportunity to broaden your skills.

Why this role matters:

The nuclear industry is entering a period of growth, in line with government ambitions, with increasing public interest in energy security and net zero. With new power stations planned, there has never been a more important time to communicate what nuclear regulation is and why it matters. In this role, you’ll be right at the centre of that story. You’ll have the freedom to innovate, explore new platforms and formats, and find creative ways to bring technical, safety‑critical work to life. When we communicate well, we help build public confidence in how nuclear safety and security are regulated – and your work will directly contribute to that trust.

About you:

You’re a creative digital communicator who enjoys both strategic thinking and hands‑on content creation. You’ll bring:

• Proven experience creating and publishing engaging content across social media platforms.
• The ability to develop and deliver social media strategies that support organisational goals.
• Strong copywriting skills, with a feel for different audiences and channels.
• Confidence using data and insight to evaluate performance and improve impact.
• Curiosity, initiative and a collaborative approach to working with colleagues.

A communications or media-related qualification (such as CIPR or NCTJ), or equivalent professional experience, will support your application.

Why join ONR?

ONR’s values are supportive, open-minded, fair and accountable, and we genuinely invest in our people. You’ll benefit from flexible, hybrid working from our offices in Bootle, Cheltenham or London, alongside a strong focus on wellbeing, inclusion and professional development. You’ll also be working with passionate experts across the organisation, which means no shortage of fascinating stories to tell. If you want to use your digital skills to make important work visible, understandable and trusted, we’d love to hear from you. Apply now to help shape how the UK understands nuclear safety.
