Thales is a global technology leader with more than 83,000 employees on five continents. With over 7,500 people in the UK, operating across defence, space, aerospace, and digital security, we help build a future we can all trust.

Though primarily based at Devonport, there will be a need to travel to other RN bases across the UK, occasionally overseas, and occasional requirements to go to sea to provide support for our customer.

Our purpose is to be the leading provider of underwater sensors and decision superiority, helping navies across the world keep our friends, families and all of us safe. We cover four sectors: Mine Counter Measures, Anti-Submarine warfare, Services and Future Capabilities.
