Commercial Manager 2-3 Year FTC (Civils Engineering & Construction) – SMR Programme
Great British Energy – Nuclear is an arms-length body of the Department for Energy Security and Net Zero, dedicated to advancing new nuclear technologies in Great Britain.
We play a key role in delivering nuclear new build, strengthening UK energy security, and meeting the country’s net-zero carbon emissions targets. Our focus is on fostering innovation, driving investment, and coordinating efforts to create a resilient and sustainable energy future.
Our first priority was the technology selection process for Small Modular Reactors (SMRs), initiated in 2023. SMRs offer potential advantages over traditional nuclear plants—faster deployment, modular factory-based construction, and more flexible deployment options. In June 2025, we secured Rolls-Royce SMR as the preferred bidder for the UK’s first SMRs, following a rigorous selection process.
Great British Energy – Nuclear operates with trust, collaboration, challenge, care and drive. We aim for faster impact, embracing a culture of equality, diversity, and inclusion.
Our Values
- Trust: Safety and integrity drive everything we do.
- Collaboration: Teamwork and diverse expertise propel us forward.
- Challenge: Curiosity and bold thinking foster innovation.
- Care: Every interaction is thoughtful, inclusive, and respectful.
- Drive: We deliver tangible differences that matter.
