About the opportunity:

Lead delivery of a major section of the Sizewell C programme—one of the UK’s largest infrastructure and nuclear new‑build projects. This role supports safe, timely, and efficient delivery of capital works across the Main Development Site, contributing directly to the UK’s Net Zero ambitions.

Purpose

Reporting to the Site Delivery Director, you will provide leadership across a multi‑discipline area of the site, acting with delegated Principal Contractor responsibility. You’ll oversee Senior Managers and matrix teams delivering Enabling Works, Major Civils, Networks and Buildings, ensuring compliance, performance, and integration across programmes and alliances.

• Manage NEC/FIDIC contracts and commercial performance.

• Build effective relationships across all project teams.

Here’s What You’ll Need:

• Proven delivery leadership within complex, highly regulated environments—ideally nuclear.

• Strong background in heavy civils, reinforced concrete, formwork systems, and major structures.

• Experience with EPCM delivery, contract strategies, procurement and commercial close‑out.

• Robust project controls capability (risk, schedule, change, EV).

• Experience working under ONR/EA/nuclear site licence regimes and safety culture principles.

• Competent with estimating, scheduling, risk tools and major construction contract management.

• Effective communicator with strong influencing, organisational and analytical skills.

• Understanding of EPR design highly desirable.

Qualifications

• Degree in Civil/Structural Engineering or Construction Management.

• Chartered Engineer (ICE/IStructE/CIOB) preferred.

• Project management accreditation (APM, PRINCE2) beneficial.

• Full lifecycle project management experience and knowledge of nuclear‑grade quality standards.
