Description
The Geotechnical Sub Alliance (GSA) is at the forefront of the Sizewell C nuclear power station development - one of the UK’s largest and most exciting infrastructure programmes.
We’re responsible for preparing the foundations of the entire site: designing and constructing cut‑off walls, retaining structures, soil improvements and more. Using advanced geotechnical engineering and world‑class construction technologies, this is a rare opportunity to contribute to a national project that will shape the UK’s clean‑energy future.
The Role
We are seeking an experienced Senior Site Engineer to lead multiple workfronts delivering complex ground‑engineering works. You will take ownership of safety, quality, programme and commercial performance across your scope, providing strong technical leadership, mentoring junior engineers and maintaining effective relationships with clients, alliance partners and site stakeholders.
This role operates within an NEC4 Alliance environment and requires sound engineering judgement, disciplined controls and confident leadership on site.
