Sellafield is the only site in the country that can safely manage all forms of nuclear waste, with our teams finding new ways to ensure it is kept safe until a permanent disposal facility is ready. We are also guardians of the UK’s largest stockpile of nuclear materials.

In the past, we have been responsible for breakthroughs such as the world’s first full-scale commercial nuclear power station, and today we are helping to keep lights on across the UK by safely receiving and storing spent nuclear fuel from the UK’s fleet of power stations.

At Sellafield Ltd there’s decades of opportunity over next 100 years and beyond. The scale of this once-in-a-lifetime undertaking gives our people unprecedented freedom. We need a workforce who are ready to be world-leading experts in shaping the UK’s sustainable nuclear future.

Life in Cumbria

Our Site Engineering programmes are based in West Cumbria, right on the edge of the breath-taking Lake District National Park. It’s a place where your weekends can be filled with hiking, cycling, or kayaking and your evenings end with sunsets over the fells. Away from the bustle of big cities you’ll enjoy fresh air, open space and a lower cost of living – without missing out on communities, activities or connections. And when you do fancy a city break, Manchester, Newcastle and Glasgow are just a few hours away. It’s the perfect balance of career opportunity and quality of life.

Enjoy affordable housing and living costs that go much further than big cities. Rural doesn’t mean isolated, you’ll still find shops, restaurants and gyms – just without the city chaos.
