The Opportunity

At Hinkley Point C (HPC) we are building two new nuclear reactors, the first in a new generation of nuclear power stations in the UK providing low carbon electricity for around six million homes.

This is your chance to join a project that’s redefining what’s possible in engineering and infrastructure. As a Building Coordinator, you’ll work within the Joint Design Office (JDO), helping to align design and construction activities across key buildings and packages. You’ll be the vital link between EDF’s Nuclear New Build (NNB) team and major contractors, ensuring technical interfaces are managed and milestones are met.

You’ll thrive in a fast-paced, collaborative environment where your coordination skills and technical insight will directly impact the success of one of the UK’s most important energy projects.

You’ll be part of the Joint Design Office (JDO), where your role will be to coordinate engineers across multiple disciplines, ensuring smooth collaboration and timely delivery of design packages. You’ll monitor performance using key metrics and help maintain high technical standards across all deliverables.

Your day-to-day will involve managing design changes, resolving technical issues, and ensuring alignment between design and construction teams. You’ll play a key role in readiness reviews and help unblock multi-disciplinary challenges that could impact progress.

Reporting to the JDO Area Lead and the Nuclear Island Engineering Manager, you’ll be a problem-solver and facilitator—keeping communication flowing, risks managed, and workloads balanced to keep the project on track.

Who Were Looking For

• You’ll bring a proactive mindset, with the ability to work independently and plan effectively under broad supervision.
• Your background in engineering - whether mechanical, electrical, or civil - will be supported by experience in design, drafting, or construction.
• You’ll be confident managing complex technical issues and collaborating across teams to find practical solutions.
• You’ll have a solid understanding of contract management (particularly NEC), CDM regulations, and be comfortable using systems to maintain accurate records.
• Your communication and facilitation skills will be key, as will your ability to identify improvements and drive progress.
• A degree or equivalent experience in engineering is essential, along with a structured, pragmatic approach to managing risks and delivering results.

Join Assystem and become a key player in delivering critical nuclear projects that shape the future of energy. Embrace this opportunity to excel in a dynamic environment where your expertise and leadership will drive global innovation.
