Shape the organisation behind one of the UK’s most important infrastructure projects
Sizewell C is moving from ambition into delivery. Following Final Investment Decision, we are building not just a nuclear power station, but a future-ready organisation that will operate under intense regulatory, public and political scrutiny for decades to come.
This is a rare opportunity to sit at the heart of that challenge.
As Organisational Design Lead, you will work directly with the Executive Leadership Team to translate strategic intent into a coherent, efficient and resilient organisation. You will set the design standards, challenge assumptions, and ensure the structure we build is fit for a complex, multi-phase nuclear programme and long-term operations. This role carries real influence, real accountability and real impact.
What You’ll Be Responsible For
Strategic leadership
This role carries nuclear safety responsibilities, with accountabilities defined within the Nuclear Baseline. Your work will directly influence organisational effectiveness, assurance and compliance.
Essential
What we’re looking for
You will be designing an organisation that matters. One that must deliver value for money, meet the highest regulatory standards and support the UK’s long-term energy security. Few roles offer this level of access, influence and legacy.
If you want to shape the organisation behind one of the most significant infrastructure projects of our time, we would like to hear from you.

If you are an exceptional leader who thrives in complex environments and are passionate about shaping the future of work, we’d love to hear from you.
Additional Information
Join the team at Sizewell C. Our vision is to Lead The Way On Nuclear.
The Sizewell C team is one of the most exciting and largest new megaprojects in the UK, whilst being at the forefront of the UK’s climate change agenda and energy policy. We have begun constructing a 3.2-gigawatt nuclear power station on the Suffolk coast in the East of England replicating, wherever possible, the design used for Hinkley Point C, another nuclear power station being built in Somerset.
When built, Sizewell C will be one of the largest power stations to operate in the UK. The power station will generate low carbon electricity for at least 60 years, supplying over 6 million homes and supporting around 7% of the UK’s current electricity needs.
Our vision is to Lead The Way On Nuclear. We want Sizewell C to define what good leadership for the nuclear industry and British infrastructure looks like and deliver on it. We understand the feats of organisation, logistics, collaboration and imagination that building nuclear requires. We are building for the next generation for their home-grown energy, energy price stability and ultra-low carbon power in abundance. We also want to set the benchmark for maximising long-lasting social value as we build and demonstrate how smart collaboration can work for the benefit of communities – locally, regionally and nationally.
We are the first nuclear power station in the UK to be funded under the Regulated Asset Base funding model (RAB). Our largest shareholder is the UK Government, alongside equity partners La Caisse, Centrica, EDF and Amber Infrastructure.
Sizewell C operates within a complex and fast-moving stakeholder environment, engaging with a wide range of partners including government bodies, regulators, local communities, supply chain partners, and international collaborators. This makes Sizewell C a uniquely stimulating place to work — where navigating evolving priorities, balancing interests, and building trusted relationships is just as critical as technical excellence. For those who thrive in dynamic, multi-dimensional settings, it offers unmatched professional challenge and growth.
When joining Sizewell C, you may wonder why you are contacted by colleagues with an EDF email or see the EDF logo on portals that you access and/or documentation you receive; this is because we have partnered with EDF for the provision of a number of support services whilst we complete a successful transition out of the EDF group.
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.
By submitting an application to this role, you acknowledge that you have read and understood Sizewell C’s employee privacy policy and EDF's employee privacy policy. Just to let you know, EDF will be processing and sharing information about your application on behalf of Sizewell C.
