Contract: Permanent, full-time.

Closing Date: Tuesday 21st July 2026

What’s in It for You

• Bonus: 5% annual incentive

Overview

As PM you will work as part of the Civil Works Programme, which comprises a series of projects that will be delivered over a 10-year period. Each element of the scope has been assigned to a combination of participants that will be responsible and accountable for the delivery. The Civils Programme will deliver the Sizewell C Civil Engineering scope to support the MEH erection in the Nuclear, Conventional and Heat Sink islands.

The Civil Works Programme is responsible for delivering:

• Enabling and Earthworks: sea defences, access facilities, civil engineering work to support site establishment, diaphragm walling around the nuclear plant footprint, dewatering, excavation and earthworks.
• Tunnelling and Marine: beach landing facility, jetty, shafts and intake and outfall tunnels for the nuclear plant cooling systems.
• Main civil engineering: technical galleries, cooling system pipework, foundation base slab and over 70 large buildings for the nuclear plant.

To successfully deliver the Programme requires excellent coordination and integration with the Site Delivery, Site Operations, and Mechanical / Electrical / Heating (MEH) Alliance.

The execution strategy involves:

• Maximising replication of HPC design to limit the extent of First of a Kind design to site-specific elements.
• Introduction and establishment of a programme management structure.
• Using learning from the HPC project to optimise and simplify working practices and processes to maximise site productivity.
• Intelligent replication of the HPC supply chain.
• Joint commitment to truly collaborative working, and an Alliance delivery and commercial model that enables this.

Principal Accountabilities, Activities and Decisions

As Project Manager your role will:

• Lead the interface with Engineering and Technical (design) to ensure timely delivery of Design, as well as incorporation of Learning from HPC, and integration of SZC Modern methods of Construction.
• Facilitate the technical instruction of changes with various design stakeholders, and reach out to back-office design entities.
• Be responsible for the timely delivery of engineering studies by the RD or by key contractors and for ensuring they meet the needs of the SZC project.
• Drive the implementation of SZC site‑specific design changes into the design deliverables in their programme, including contract specifications to enable robust pricing.
• Manage internal interfaces (between contracts and systems) and external interfaces (between programme scopes) to ensure a coordinated approach to design and delivery.
• Manage early engagement with stakeholders (including equipment suppliers, designers and CWA) to identify opportunities and changes.
• Manage the technical elements of the procurement, delivery and methodology for Civil Works.
• Ensure that lessons‑learnt and knowledge‑capture are practiced as business as usual.
• Develop and implement strategies and plans in line with the overall programme execution plan (PEP).
• Define the work scope to be delivered within the contract or package of work and the interfaces to the other elements of the programme.
• Drive the delivery of the contract or package activities to ensure they are delivered safely, on time, to budget, meeting business requirements.

At Sizewell C we encourage and embrace diversity and how it can improve our experience and performance at work. It is a requirement that those who join us have the right to work in the UK. Whilst sponsorship may be a possibility that we can explore, we are fully committed to local recruitment where possible, and those already holding the right to work in the UK. To be appointed to this role, you will need to meet the criteria for Security Vetting, which will, ordinarily, require you to have been a resident of the UK for at least three of the past five years.
