About Us

Rolls‑Royce SMR is here to transform how nuclear energy is delivered—cleaner, faster and at global scale. Our teams are developing one of the world’s most advanced small modular reactors, helping secure affordable, low‑carbon energy for generations to come. We’re doing something that’s never been done before. We’re revolutionising an industry. That’s a once-in-a-career opportunity for those excited by such a challenge. This is more than just a job; this is a legacy.

Role Purpose

We’re looking for proactive and collaborative people to join our growing Nuclear Security Case team as we continue to design the Rolls‑Royce Small Modular Reactor (SMR). This role sits at the heart of our mission to deliver safe, secure, low‑carbon power for the UK and beyond. As an OT/ICS Cyber Security professional, you would help shape a greenfield Cyber Protection System (CPS) that protects essential operational technology (OT) within our SMR design. As a member of an assurance driven team you’ll work closely withtheICSCyberSecurityLead, engineers, system owners, and our Environment, Safety and Safeguards colleagues to define robust cyber security requirements, help future‑proof our security design and assure the cyber security of systems and architectures. You will also work closely with regulatory inspectors to ensure regulatory requirements and expectations are met, communicating effectively how this is achieved. This is an industrial control system cyber security role, supporting the protection of critical systems within a nuclear environment.

What You’ll Be Doing

• Support the development and implementation of Cyber Security Risk Assessments and contribute to CPS requirements, specifications and control sets.
• Apply Secure‑by‑Design principles and help shape Claims, Arguments and Evidence for the Generic Design Assessment (GDA).
• Translate complex cyber risks into clear, meaningful insights for technical and non‑technical stakeholders.
• Support colleagues across engineering, safeguards and safety functions, ensuring cyber security is embedded into design decisions at every stage.
• Contribute to site‑specific design work in the UK and internationally as the programme evolves.

• Good technical writing skills, ideally with experience writing and reviewing design documentation (i.e. system design requirements, system design descriptions, etc.)
• Awareness of IT/OT interaction and ideally experience in highly regulated, safety‑critical environments.
• Ideally have experience liaising/interacting with regulatory inspectors.
• Collaboration & Communication Ability to communicate cyber risk clearly to specialists and non‑specialists, responding constructively to challenge.
