Role Overview:
Join Sizewell C at a pivotal stage in the development of one of the UK's most significant nuclear infrastructure projects. As a Nuclear Safety Engineer, you will play a key role in establishing the pre-operational nuclear safety group arrangements that will underpin the future safe and reliable operation of the power station.
You will be a key link between the nuclear safety case and the future operator, working with a wide range of stakeholders to ensure the fundamental nuclear safety principles of cooling, controlling and containing the core are upheld. You will also help demonstrate compliance with national and international regulatory requirements.
Reporting to the Nuclear Safety Manager, you will join the Pre-Operations Technical and Safety Support Programme. This programme is responsible for ensuring the future operating organisation has the people, processes, equipment, facilities and documentation needed to operate Sizewell C safely and reliably, in line with all licence, permit, regulatory and statutory requirements.
As the pre-operational programme develops, you will help establish and deliver four key nuclear safety workstreams:
- Reactor physics, nuclear fuel and criticality
- Safety case and risk
- Regulation, legislation and reporting
- Operations, engineering and maintenance support
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
You will specialise in at least one of these areas while developing a strong understanding across the wider function. This will be an opportunity to build technical breadth, contribute to a growing team and help shape the nuclear safety arrangements for a new nuclear power station.
You will work closely with the pre-operations team at Hinkley Point C, building strong relationships and ensuring learning and experience from Hinkley Point C are embedded within Sizewell C. Regular time at the Hinkley Point C site will be expected, alongside collaboration with other teams across Sizewell C.
Role Responsibilities
- Develop and deliver activities within the pre-operational nuclear safety strategy, specialising in one or more key workstreams while maintaining a broad understanding across the wider function.
- Provide nuclear safety expertise to support the development of the future Sizewell C operating organisation and demonstrate compliance with the Nuclear Site Licence and relevant regulatory and statutory requirements.
- Contribute to the development, understanding and application of the nuclear safety case, applying nuclear safety, reactor physics and criticality knowledge to support safe and reliable plant operation.
- Support the development of operational, engineering, maintenance and emergency arrangements.
- Represent the interests of the future operator across the wider pre-operations function, working collaboratively with various internal stakeholders.
- Build strong relationships with Hinkley Point C counterparts, sharing learning and ensuring relevant experience is embedded within the Sizewell C Pre-Operations Function.
- Provide constructive challenge, identify opportunities to improve nuclear safety and ways of working, and adapt effectively to changing priorities within a dynamic pre-operational environment.
- Contribute to the development of a small, effective and resilient Nuclear Safety team as the pre-operational programme progresses.
About You
- Degree or equivalent qualification in engineering, science or a related discipline.
- Understanding of nuclear reactor physics, the Nuclear Site Licence and wider nuclear regulatory requirements.
- Strong technical understanding of nuclear power plant operations, ideally related to Pressurised Water Reactor (PWR) technology.
- Understanding of the role of a Nuclear Safety Group within an operational nuclear power station.
- Understanding of the nuclear safety case, including its principles, purpose and application within an operational environment.
- Ability to champion nuclear safety and confidently provide constructive challenge to colleagues, peers and stakeholders.
- Strong relationship-building skills, with the ability to collaborate effectively across functions and organisations.
- Flexible and adaptable, able to work effectively in a dynamic project environment with changing priorities.
- Self-motivated, proactive and able to take ownership of work within your area of responsibility.
