Job Description
Our two-year Graduate Programme is designed to get you up to speed quickly, give you exposure to live projects, and help you develop both technical and professional skills.
You’ll benefit from:
Access to mentors and technical experts
Peer-to-peer learning through Graduate Forums
An upskilling framework tailored to your development
The opportunity to rotate across industries, customers, and locations
Over the two-year self-directed programme, you’ll gain a unique insight into the nuclear industry. This starts with broad exposure across teams and customers and evolves into discipline-focused work that aligns with your career ambitions. Within our programme, there will be opportunities to rotate through different teams and projects to help grow your knowledge, skills and behaviours.
My profile
We’re looking for graduates who have (or are expecting) a degree in Engineering, Mathematics, Science, or a closely related discipline and who are interested in developing a career in nuclear safety within highly regulated environments. If you’re curious about how safety is designed into complex systems, enjoy structured problem-solving, and want to understand how risk is assessed, justified, and managed across the full lifecycle of nuclear facilities, this could be the ideal next step for you.
To join our Graduate Scheme, you must be a UK sole national and a UK resident, as this is required for the type of work we do. You’ll also need to be able to obtain a minimum of Baseline Personnel Security Standard (BPSS) clearance, with some roles requiring higher levels of clearance. As part of the programme, you should also be willing to relocate or travel within the UK, and we’ll provide relocation support where needed.
