Join the team at Sizewell

C. Our vision is to Lead The Way On Nuclear. The Sizewell C team is one of the most exciting and largest new mega projects in the UK, whilst being at the forefront of the UK's climate change agenda and energy policy. We have begun constructing a 3.2-gigawatt nuclear power station on the Suffolk coast in the East of England replicating, wherever possible, the design used for Hinkley Point C, another nuclear power station being built in Somerset.

When built, Sizewell C will be one of the largest power stations to operate in the UK. The power station will generate low carbon electricity for at least 60 years, supplying over 6 million homes and supporting around 7% of the UK's current electricity needs.

Our vision is to Lead The Way On Nuclear. We want Sizewell C to define what good leadership for the nuclear industry and British infrastructure looks like and deliver on it. We understand the feats of organisation, logistics,…
