Job description

Help deliver a project of national significance. Lead the site that will shape the future of UK nuclear and major infrastructure delivery.

Sizewell C is entering one of the most important phases in its journey, and we are looking for an exceptional Site Delivery Director to lead the planning, coordination and delivery of construction activity across the Sizewell C site.

This is not simply a senior construction leadership position. It is an opportunity to play a defining role in the delivery of one of the UK’s largest, most complex and most closely scrutinised infrastructure programmes.

Reporting to the Chief Operating Officer, you will be accountable for the site delivery of Sizewell C, bringing together programmes, engineering, construction, commercial, project controls, contractors and supply chain partners to create a genuinely integrated delivery organisation.

You will lead the Site Delivery organisation and hold accountability for a £3.2bn Site Delivery budget across the life of the project, operating in an environment where safety, quality, schedule, cost, productivity and value for money are paramount

Closing date for applications - Tuesday 17th November 2026

The opportunity

Sizewell C has an ambition not just to build another nuclear power station, but to lead the way in how major nuclear and infrastructure projects are delivered in the UK.

Building on the design and lessons of Hinkley Point C, Sizewell C is seeking to innovate in delivery, increase productivity, expand the use of off-site manufacturing and modern methods of construction, and achieve significant improvements in time and cost.

As Site Delivery Director, you will be at the centre of that ambition.

You will set the conditions in which thousands of people, multiple programmes and a complex supply chain can perform at their best. You will ensure construction activities are integrated, interfaces are managed, decisions are taken at the right level, and multidisciplinary teams have the clarity, capability and accountability required to deliver safely and effectively.

This is leadership at significant scale and with national visibility.

You will work across the Sizewell C organisation and with Tier One suppliers, the nuclear industry, trade unions, local communities, Government and key regulatory bodies including the Office for Nuclear Regulation, Environment Agency and Ofgem.

What you will lead

Your remit will include:

• Overall site delivery, accountable to the Chief Operating Officer for the construction delivery of Sizewell C.
• Principal Contractor leadership, ensuring Sizewell C fulfils its responsibilities while creating an environment where safety and quality are never compromised.
• Integrated construction delivery, aligning programmes, engineering, commercial, project controls and the supply chain around best-for-project outcomes.
• Productivity and innovation, maximising opportunities presented by modern methods of construction and off-site manufacturing while managing risk intelligently.
• High-performing multidisciplinary teams, establishing clear objectives, accountabilities, interfaces, decision rights and consistent ways of working.
• Supply chain leadership, building strong relationships with senior industry leaders while challenging established ways of working where better outcomes are possible.
• Stakeholder leadership, representing Sizewell C with communities, regulators, Government, unions and other critical stakeholders.
• Culture and capability, creating an organisation able to meet the demands of each stage of construction while developing leaders and capability for the future.

About you

We are looking for an establishedleader of leaders with the credibility, judgement and experience to operate successfully in an exceptionally complex delivery environment.

You will bring substantial Director-level experience of major projects, programmes or complex construction environments, with evidence of leading multiple senior delivery leaders, significant business units or major portfolios.

You will combine:

• Significant leadership experience in a highly regulated environment, ideally nuclear or comparable major infrastructure.
• A strong record of industrial and nuclear safety leadership.
• Experience of major programme budgets and balancing safety, quality, schedule, cost and risk.
• Proven success building integrated delivery organisations and multidisciplinary teams.
• Deep understanding of Principal Contractor responsibilities and the CDM Regulations.
• Strong commercial judgement and the ability to build productive, challenging relationships with major supply chain partners.
• Experience of organisational design, mobilisation, transformation, capability and resource planning at scale.
• The ability to use project controls, data, performance measures and early-warning information to drive decisive action.
• Exceptional stakeholder management, influencing and communication capability.
• Chartered status in an appropriate engineering, construction or project profession, or equivalent senior professional experience.

Above all, you will understand that delivering a programme of this scale requires more than technical expertise. It requiresvisible, authentic and inspirational leadership.

How we lead

Our values underpin how we expect our leaders to operate:

Be True

Lead with integrity, speak clearly, welcome challenge and create an environment where risks are surfaced early and people feel able to speak up.

Be Your Best

Set exceptionally high standards, use evidence and learning to improve, develop others and relentlessly pursue better safety, quality and delivery performance.

Be Together

Build one team across programmes, functions, partners and suppliers. Value different expertise, actively manage interfaces and put the best outcome for the project first.

The significance of the role

Sizewell C is about considerably more than the construction of a power station.

It is an opportunity to demonstrate how the UK can deliver complex infrastructure differently, applying lessons learned, modern construction techniques and integrated delivery to achieve better outcomes.

The project operates in a highly scrutinised environment, with shareholders including HM Government, La Caisse, Centrica, EDF and Amber Infrastructure, alongside debt providers and economic regulation. The expectations around transparency, delivery confidence and value for money are therefore exceptionally high.

For the right leader, this represents a rare opportunity: to shape not only the successful delivery of Sizewell C, but potentially the benchmark for the next generation of major UK infrastructure projects.

Location

Suffolk, with travel to other locations as required.
