Site Engineer

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 a proactive and organised Site Engineer to plan and manage day‑to‑day work fronts for the safe, high‑quality and efficient delivery of ground engineering works. The role is site‑based and requires strong technical capability, disciplined record‑keeping and close coordination with operations, safety, quality, commercial and procurement teams, within an NEC4 Alliance environment.

Commercial, Procurement & Contractual:
Support procurement activities including specifications, orders and subcontract administration; raise and track Early Warnings and NCEs; provide inputs to CEs and cost control; and apply NEC4 Alliance procedures, including risk‑reduction and change control processes.

Leadership &

Collaboration:

Supervise small teams and apprentices, provide constructive feedback, support basic people management conversations, and work collaboratively with multidisciplinary support teams.
