About the Opportunity

Are you good at spinning plates?

It’s not something you see very often on TV these days, but figuratively, it is a very useful skill, one of which is vital if your goal is to keep nuclear power stations operating safely, contributing to the UK’s Net Zero carbon target, or to help prepare them for decommissioning.

The UK’s five operating stations deliver 16% of the UK’s power, and it takes a large team delivering 100’s of projects to enable these stations to continue generating as well as defuel the three stations that have ceased operation - and that’s a lot of plates.

And this is where you come in

You’ll utilise your strong communication and engagement skills to achieve client, people and business outcomes, working with your team and peers that are based in different locations across the UK.

As well as focusing on the support to this framework, you’ll get involved in other aspects of our high-performing business. We’re continuously evolving and growing the business, so there’s plenty of opportunity to evolve and grow your skills and career too.
