Our Mission

At Rolls-Royce SMR, we are pioneering the deployment of affordable, low-carbon nuclear power to support global energy security and net-zero ambitions. Our Small Modular Reactor programme is designed to deliver scalable, cost-effective clean energy solutions, helping governments and industries transition to a more sustainable future.

The Team

You will join the Reactor Core function within Engineering, working in the Core Performance discipline. This is a highly specialised area focused on reactor physics, thermal hydraulics and plant response analysis. As a senior technical expert, you will collaborate with multidisciplinary teams across safety, control & instrumentation and design, while also engaging with external stakeholders including regulators. With major programme milestones ahead, including ongoing Generic Design Assessment activities and the Design Acceptance Review, your work will directly contribute to design maturity and programme success.

The Role

This is a senior technical authority position where you will lead and influence the development of reactor core performance capability across a first-of-a-kind SMR programme. You will drive advanced analysis and modelling activities, ensuring the reactor design meets stringent safety, operability and performance requirements. The role offers high visibility across the business, with opportunities to shape key decisions, support regulatory engagement and guide the evolution of analytical approaches and engineering standards.

What We’ll Need You To Do

• Lead and deliver core performance analysis across reactor physics, kinetics and thermal hydraulics, ensuring outputs are robust, high quality and aligned to programme milestones.
• Act as a recognised technical authority, providing governance, assurance and expert judgement to solve complex engineering challenges within a regulated nuclear environment.
• Drive the development and enhancement of analytical methods, tools and computational models to continuously improve capability and maintain technical excellence.
• Collaborate with multidisciplinary engineering teams to ensure effective integration of core performance within the wider plant design.
• Support regulatory activities, including GDA, by providing clear, credible technical input and responding to regulator queries.
• Mentor and guide engineers across the function, building capability and fostering a culture of collaboration, innovation and continuous improvement.

What You’ll Bring

• Significant experience in nuclear core physics, core design or core performance, with a strong track record in delivering complex engineering work within a regulated environment.
• Deep technical expertise across reactor performance disciplines, including thermal hydraulics, kinetics and core modelling, with an understanding of safety and operational constraints.
• Degree qualified in a relevant discipline (Physics, Nuclear or Mechanical Engineering), ideally with Chartered status or equivalent professional recognition.
• Experience in developing or applying advanced analytical methods and tools, alongside an understanding of regulatory expectations within the nuclear sector.
• Strong communication and influencing skills, with the ability to present complex technical information to a range of stakeholders including senior leaders and regulators.
• A collaborative and forward-thinking approach, with the credibility to lead technically while enabling high-performing teams.

Location

This role offers flexible and hybrid working, with time spent across our key UK locations including Warrington, Derby or Manchester. We support flexible working arrangements to help balance personal and professional commitments.
