Overview
Sizewell C’s business is to design, finance, construct, commission, operate, maintain, and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk. While the Company is in the construction phase, the Board’s principal focus is on the development and construction of Sizewell C on time, on budget, and to the highest quality and safety standards. The Company is maturing to meet all these requirements. Sizewell C is economically regulated by OFGEM under the RAB model similar to other UK electricity distribution networks and Thames Tideway. The construction strategy is to replicate the design of Hinkley Point C, using the majority of the same supply chain, but innovating in the way it is delivered to achieve savings in time and cost of around 20%. The Chief Commercial Officer will need to be guided by and incorporate lessons learned from the Hinkley Point C commercial delivery to achieve Sizewell C’s ambition. Following Financial Completion and Revenue Commencement, Sizewell C is fully funded and is owned by the Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.
Position
Assistant Project Manager – Sizewell C | Bristol
Opportunity
Join one of the UK’s most ambitious infrastructure programmes and help deliver the future of clean energy. Sizewell C is entering a critical delivery phase, creating exciting opportunities for Assistant Project Managers to join the Engineering & Delivery function across several major programme areas. This is an outstanding opportunity for developing project professionals to build experience on one of Europe’s largest and most complex infrastructure projects, working alongside experienced delivery teams within a highly regulated and technically challenging environment. You’ll play a key role in supporting the delivery of engineering, procurement and manufacturing activities that will help power around 6 million homes with low‑carbon electricity for generations to come.
The Opportunity
As an Assistant Project Manager, you will support the successful delivery of engineering work by the Responsible Designer (RD), alongside procurement, manufacturing and delivery of major contracts across the Sizewell C programme. Working closely with multidisciplinary teams including engineering, supply chain, quality, construction and suppliers, you’ll help drive progress across key work packages while developing valuable experience within a world‑class major programme environment. A core focus of the wider Project Management team is advancing engineering maturity and securing critical supply chain capability through the maximum possible replication of the Hinkley Point C design, helping de‑risk delivery and improve programme efficiency.
Key Programme Areas
* Mechanical, Electrical & HVAC (MEH) – Supporting the development and mobilisation of the MEH Alliance delivery model, helping shape collaborative delivery strategies informed by lessons learned from Hinkley Point C.
* Nuclear Island (NI) – Supporting delivery across systems, buildings and contracts within the Nuclear Island programme, one of the most technically complex areas of the project.
* Civil Works – Supporting the development and delivery of major civil engineering work packages, including engineering, procurement, manufacturing, construction and commissioning activities.
* Conventional Island & Balance of Plant (CI/BOP) – Supporting the delivery of engineering contracts and helping ensure technical, commercial and programme requirements are achieved safely and efficiently.
What You’ll Be Doing
* Supporting the delivery of engineering studies and design activities across your programme area.
* Working with multidisciplinary teams to prepare manufacturing, construction and engineering contracts.
* Supporting procurement and supplier engagement activities.
* Helping manage interfaces across systems, contracts and programme areas.
* Supporting implementation of Sizewell C‑specific design changes into delivery packages.
* Assisting with the identification and management of technical risks and supply‑chain challenges.
* Supporting delivery activities to ensure work is completed safely, on time, within budget and to quality standards.
* Working closely with internal and external stakeholders including suppliers, contractors and engineering teams.
* Supporting lessons learned, knowledge capture and continuous improvement activities across the programme.
* Helping coordinate project activities within a matrix delivery environment.
