Why Join Us?
Werebuilding thefuture. Sizewell C is a once-in-a-generation infrastructure project that will power Britains energy security and net-zero ambitions for decades to come. Following our recent Final Investment Decision, construction is fully greenlit. This is your chance to be part of the largest investment in homegrown clean energy in decades, delivering low-carbon electricity to 6 million homes for at least 60 years.
Whatsin It for You
Your Impact
Lead the end-to-end delivery of the Conventional Island (CI) scope for SZC Units 1 & 2 within the Main Civil Works (MCW), acting as the Owner Participant in the Civil Works Alliance. Accountable for enabling safe, quality, on-time, on-cost delivery across Engineering Interfaces, Procurement, Construction, and Handover. Operates in a peer relationship with the CWA CI Platform Delivery Lead and provides line leadership to SZC project managers and functional support.
Key Responsibilities
Contextual Information
The Sizewell C (SZC) construction programme is built around a technical and commercial business case that relies on intelligent replication of Hinkley Point C (HPC). This approach leverages mature design data, established engineering solutions, supply chain capability, and lessons learned from HPC to reduce FOAK complexity, accelerate delivery, and improve productivity.
EDFs established UK nuclear capability is a critical contributor to this strategy, providing design, engineering, assurance, and construction expertise that underpins SZCs ability to replicate, adapt and execute safely.
The SZC Civil Works Programme (CWP) comprises three major subprogrammes delivered over a 10year period:
The Main Civil Works (MCW) includes the Conventional Island (CI), Nuclear Island and Heat Sink Island scopes, with each scope delivered through integrated alliance teams combining SZC (Owner Participants) and Alliance Partners.
Key Stakeholders
The CI HoD must operate confidently and credibly in a complex, regulated stakeholder environment. Principal stakeholders include:
Knowledge, Skills, Qualifications & Experience
Behavioural Competences
Humility
Positivity
Respect
Solidarity

Additional InformationJoin 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 UKs 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 UKs 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.
