The Job Mission

This is a hands-on, site-integrated role supporting mechanical construction delivery on of Europe's largest construction projects, Hinkley Point C.

We welcome candidates from outside the nuclear sector—if you’ve worked on complex construction projects involving heavy plant, pressure systems, or large-scale utilities, you’ll find your skills highly relevant here.

You’ll typically work three days per week onsite in Bridgwater, but we need those with flexibility for five days as needed based on project requirements. If you're relocating, we offer a relocation allowance to help support your move.

Your key responsibilities will include:

* Leading and guiding site teams to deliver mechanical installation safely and efficiently

* Defining work scopes and sequencing them for practical delivery on a live construction site

* Coordinating installation activities with designers, subcontractors, and technical leads

* Identifying and resolving engineering or construction challenges in real time

* Supporting improvements to build methodology, planning, and site access

* Upholding the highest standards in health, safety, environmental, and quality compliance

* Providing updates on progress, resource planning, and readiness to the site management team

* Acting as the key link between engineering intent and field execution

Essential Skills and Qualifications

* Engineering degree or equivalent trade-based qualification

* Proven experience coordinating site-based mechanical or piping works

* CCNSG Safety Passport and IOSH Managing Safely or NEBOSH certification

* Minimum 5 years in construction or industrial environments

* Background in oil & gas, steelworks, utilities, power stations, or similar heavy industrial sectors
