How does this role play into the bigger picture at Sizewell C?

Sizewell C is a new nuclear power station being built in Suffolk, featuring two European Pressurised Water Reactor (EPR) units. This is a once in a generation project that will power millions of homes with low‑carbon energy and play a vital role in the UK’s net zero future.

Why join as an Operating Instructor?

As an Operating Instructor, you will prepare and deliver high‑quality training in EPR systems, technology, and operations. You’ll start with an intensive training and familiarisation programme at Hinkley Point C (HPC) for up to three years, including secondment into the Nuclear Skills Alliance (NSA). After this, you’ll return to Sizewell C to lead training for our future operators.

Key responsibilities include

• Completing initial training on PWR technology, EPR systems, and operational fundamentals.
• Developing and delivering classroom and simulator‑based training programmes.
• Preparing and validating training materials for SZC based on HPC replication.
• Supporting operator assessment and authorisation.
• Maintaining and improving training processes and standards.

What We’re Looking For

Essential

• Strong communication, mentoring, and problem‑solving skills.
• Ability to maintain situational awareness and work under pressure.
• Minimum qualification: HNC in a technical discipline (or equivalent).
• Experience in nuclear operations, including graduates with a relevant science or engineering degree, or similar technical roles (e.g., operational control engineers, technical instructors from power generation or grid operations).

Desirable, but not essential

• Experience operating a nuclear power plant or Pressurised Water Reactor.
• Previous technical training delivery experience.
• Knowledge of Systematic Approach to Training and Nuclear Operator Fundamentals.

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.

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.

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.
