Summary:

Are you passionate about nuclear energy’s role in achieving Net Zero? Do you enjoy solving complex engineering problems across the nuclear lifecycle — from new builds to decommissioning? Join a fast-growing engineering consultancy working at the forefront of the UK’s low-carbon energy transition.

We're looking for experienced Nuclear Engineers with a solid background in engineering projects within the nuclear sector. Whether you're supporting new reactor design, contributing to safety case development, or helping manage legacy waste challenges, this is your chance to make a national impact.

What You’ll Do:

You’ll work on high-impact projects across the UK’s nuclear landscape, including:

• Developing engineering strategies for new builds, operational reactors, and decommissioning.
• Authoring high-quality technical reports, specifications, and safety documentation.
• Providing expertise across nuclear, mechanical, and process engineering disciplines.
• Supporting clients with concept design, system troubleshooting, and lifecycle analysis.
• Mentoring junior colleagues and providing technical leadership.
• Leading project delivery – balancing time, cost, and quality objectives.
• Generating client proposals and identifying new business opportunities.
• Building and maintaining long-term client relationships.

Current Projects You Could Join:

• Supporting the safety case for Hinkley Point C and Sizewell C.
• Designing containment systems for the next generation of Small Modular Reactors (SMRs).
• Exploring novel technologies for the disposal of intermediate level solvent waste.
• Delivering maintenance outage support to the UK’s fleet of Advanced Gas-Cooled Reactors (AGRs).
• Engineering studies for front-end design of new systems at Sizewell B.

What We’re Looking For:

• A degree in Nuclear Engineering, Mechanical Engineering, Process Engineering, or a similar field.
• Prior experience in the nuclear industry or in other regulated engineering environments.
• Familiarity with UK nuclear safety regulations, industry codes, and standards.
• Hands-on involvement in design, delivery, commissioning, or troubleshooting of complex systems.
• Strong technical writing skills and ability to communicate with a range of stakeholders.
• Ability to support clients with problem-solving, system analysis, and risk-based decision-making.

Please note: Due to the nature of this work, applicants must meet UK National Security Vetting requirements.

What’s In It For You?

• Flexible hybrid working (home, office, and client site).
• 25 days’ annual leave + buy/sell holiday scheme.
• Company pension scheme & performance-based bonus.
• Professional membership fees paid & structured development support.
• Cycle to work & season ticket loan schemes.
• Employee share purchase plan.
