Senior Project Manager

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. Overall, whilst the Company is in the construction phase, the Boards’ 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. Sizewell C 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 CCO 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.

Be part of one of the most ambitious infrastructure programmes in Europe. Sizewell C is now firmly into delivery following Final Investment Decision, marking a major milestone in the UK’s energy future. This is a rare opportunity to join a nationally significant project that will provide secure, low‑carbon electricity to around 6 million homes for generations to come.

We are looking for experienced Senior Project Managers and Project Managers to lead the end‑to‑end delivery of major Systems, Structures and Components (SSCs) across the Sizewell C programme, managing complex Engineering, Procurement, Construction and Commissioning (EPCC) scopes in a highly regulated, technically demanding environment. These are high‑profile leadership roles where you will drive delivery across large‑scale nuclear infrastructure packages valued between £100m and £500m, working alongside world‑class engineering, construction and supply chain teams.
