About the Role

We’re looking for an experienced Site Engineer to join a major wastewater infrastructure project in Somerset.

This is a site-based position on a single project, with an expected duration of 10–12 months, offering a good level of continuity and stability.

You’ll play a key role in supporting the successful delivery of the works, working closely with the Site Manager, project engineers, subcontractors and wider delivery team.

• Ensuring all works are carried out in line with health, safety, environmental and quality requirements
• Maintaining clear communication with site management, designers, subcontractors and suppliers
• Adhering to all relevant company and client policies and procedures

About You

You’re an experienced and technically capable Site Engineer with a strong background in water or civil engineering.

You have a minimum of five years’ relevant experience and are confident working on complex infrastructure projects involving pipelines, structures and below-ground works.

You’re comfortable working from drawings and specifications, setting out accurately and identifying potential technical issues before they affect progress.

You’ll also be confident communicating with Site Managers, subcontractors, designers and the wider project team.

Experience across pipelines, pumping stations, process units, chambers, FRC structures and concrete works would be particularly beneficial.

You’re organised, safety-conscious and able to manage your workload effectively in a fast-paced construction environment.
