Site Engineer – Ground Engineering | Sizewell C

About the role

Amazing infrastructure isn’t the only thing that gets built here. Incredible careers do too. Join Balfour Beatty Ground Engineering as a Site Engineer on the Sizewell C project and you’ll be part of one of the UK’s most significant infrastructure programmes.

Working within the Geotechnical Sub-Alliance (GSA), you will help deliver complex ground engineering works that prepare the site for the construction of the new nuclear power station on the Suffolk coast. The scope includes major enabling works such as cut‑off walls, soil improvement, bearing elements, and retaining structures. Using advanced construction techniques including piling, diaphragm walling, soil mixing, and grouting, the team utilises specialist equipment such as hydrofraises, hydraulic grabs, piling rigs, and soil mixing plants to deliver safe, efficient, and high‑quality results within a collaborative alliance environment.

As a Site Engineer, you will play a key role in supporting the day‑to‑day delivery of ground engineering work fronts, ensuring activities are carried out safely, efficiently, and in accordance with programme, quality, and commercial requirements.

In this role you will support the planning and management of day‑to‑day site activities across assigned work fronts, ensuring works are delivered safely and in line with project specifications, drawings, and engineering standards. You will coordinate labour, plant, and materials required for the works while ensuring compliance with Inspection and Test Plans, method statements, permits, and other site documentation.

You will support health and safety initiatives across site by delivering daily briefings and toolbox talks, ensuring teams understand any changes to methods or permits and maintaining accurate attendance and action records. The role will also involve contributing to incident investigations and ensuring safe systems of work are implemented and followed.

A key part of the role will involve managing and maintaining quality documentation. You will assist in drafting and implementing Inspection and Test Plans for ground engineering works, arranging inspections and testing activities, raising and managing non‑conformance reports, and maintaining marked‑up drawings including red‑line and as‑built records for project handover.

You will support procurement activities by translating operational requirements into specifications, raising orders, managing deliveries, and coordinating plant and material movements on site. This includes assisting with subcontract administration and ensuring resources are available when required to support the construction programme.

Monitoring productivity will also form part of your responsibilities. You will track rig performance and production rates against targets, identify opportunities for improvement, and highlight constraints or delays so that corrective actions can be implemented quickly.

Working closely with the wider project team, you will help maintain short and medium‑term look‑ahead programmes, supporting the sequencing of works and monitoring progress against key milestones. You will also contribute to delay analysis and support programme updates where required.

The role will involve supporting commercial and contractual processes under the alliance NEC4 contract model. This includes assisting with early warning notices, non‑compensation events, and providing inputs for change events and quotations while supporting the project’s cost control processes.

You will also take on leadership responsibilities on site, supervising small teams or apprentices, supporting collaboration across project teams, and helping maintain a proactive and solution‑focused working environment.

We are looking for someone with experience in site or contracts engineering within the construction or ground engineering sector. You should be confident working with engineering drawings and specifications and capable of coordinating site activities while maintaining accurate technical and quality records.

Strong communication skills are essential, with the ability to engage effectively with site teams,…
