What You Will Be Doing: 

As a Science & Engineering Graduate at Sizewell C, you will gain hands-on experience, develop technical and professional skills, and contribute to meaningful projects that support the UK’s journey to net zero. 

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. 

You will work with a wide range of stakeholders to help build and establish one or more of the following key workstreams: 

• Reactor physics, nuclear fuel and criticality 

• Safety case and risk 

• Regulation, legislation and reporting 

• Operations, engineering and maintenance support 

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. 

Previous graduates have gone on to become: Technical Managers, Senior Leaders and Heads of Function.   

Your Work Location 

Whilst you will be based at Gloucester office with placements of 3– 6 months, you may also be required to travel to another location for your placements, to support other business units and to expand your knowledge and experience of the Nuclear Industry.
