About the Opportunity

We are currently recruiting for a Principal Mechanical Engineer to join our Energy business, which is entering an exciting phase of opportunity: supporting a key client’s UK nuclear fleet through a business transformation; supporting new small modular reactor developers. Our work is varied, covering Licensing, New Build, Generation, Life Extension, and Defueling, and our capabilities are in demand across the nuclear sector.

This role will be based at one of our Energy offices (Newcastle, Warrington, Glasgow, Gloucester, Stockton, Bristol or Knutsford ).

Your role will be to manage and deliver mechanical design solutions to time, cost and quality on projects of varying sizes. If you’re familiar with project delivery, you’ll know that they have lots of moving parts and complexity, which is why you’ll be working alongside our Operations Managers and Engineering Managers to enable delivery of maximum value.
