Are you ready to help deliver one of the UK’s most significant infrastructure projects?
The Geotechnical Sub Alliance (GSA) at Sizewell C is seeking a proactive, people‑focused Deputy Plant Manager to join our high‑performing team working at the cutting edge of geotechnical engineering.

This is an exciting opportunity to help manage a large, diverse fleet of specialist plant and equipment—hydrofraises, piling rigs, soil‑mixing plants, diaphragm walling tools, and more—all essential to building the foundations of the new nuclear power station.

About the role:

As Deputy Plant Manager, you’ll play a key role in ensuring our plant operations run like clockwork, supporting both day‑to‑day activity and long‑term project delivery. You will:

• Lead and support the Plant Yard Team, fostering a positive, safety‑first culture

• Manage plant availability, utilisation and reporting, ensuring assets meet project standards
• Collaborate with Fitters, Welders, Mechanics and Site Teams to plan maintenance and ensure resources meet production needs
• Keep the Asset Register accurate and up to date
• Coordinate plant movements with Logistics
• Source external plant when needed and evaluate repair options
• Identify opportunities for continuous improvement in operations
• Support recruitment, staff development, and the PDR process
• Ensure compliance, standards and procedures are consistently upheld
   

If you thrive in a busy operational environment and love the challenge of keeping complex moving parts aligned, this role is for you.
