Qualifications

• Experience delivering complex system design in nuclear or similarly regulated industries.
• Engineering degree or equivalent experience in design delivery.
• Strong understanding of systems engineering concepts: requirements, integration, structured design.

Responsabilités

• Lead delivery of system design packages aligned to programme requirements and deadlines.
• Develop and manage system requirements with traceability and verification evidence.
• Produce high-quality documentation: design reports, system definitions, substantiation artefacts for safety cases and regulatory submissions.
• Collaborate with internal teams and regulators to resolve design challenges and maintain momentum.
• Identify and manage risks and opportunities within the design scope with mitigation plans.
• Apply design governance and assurance processes to maintain quality and compliance.
• Provide technical leadership to engineers and help grow team capability.

Our Mission

At Rolls-Royce SMR, we are revolutionising clean energy through the delivery of scalable, affordable nuclear power. Our mission is to provide reliable low-carbon energy that supports global net zero ambitions while driving innovation and engineering excellence at every stage of the programme.

The Team

You will join the Reactor Plant and Systems team, a multidisciplinary engineering function responsible for the design and development of the systems that underpin the Reactor Island. The team brings together expertise across mechanical, fluid and safety-critical systems, working collaboratively to develop robust, licensable, and high-performing designs. Operating within a highly regulated environment, the team plays a critical role in progressing the programme through detailed design and regulatory approval. You will work closely with internal specialists, external partners and regulators, contributing to a collaborative culture focused on delivery, safety and continuous improvement. As a Senior Engineer, you will also provide technical leadership and support to a small team, helping to shape both design outcomes and team capability.

The Role

As a Senior Reactor System Design Engineer, you will lead the development of complex process and mechanical system designs across the Reactor Island. You will play a key role in translating high-level requirements into robust, evidence-based design solutions that meet stringent regulatory and safety expectations. This role offers exposure to the full lifecycle of system design, from early concept development through to detailed design, substantiation and licensing support. You will contribute directly to the maturity and integration of the overall plant design, ensuring alignment with programme milestones and industry best practice while supporting the safe and efficient delivery of the Rolls-Royce SMR solution.

What We’ll Need You to Do

• Lead the delivery of system design packages so that outputs are technically robust, aligned to programme requirements and delivered to agreed timescales.
• Develop and manage system requirements to ensure designs are clearly defined, traceable and supported by appropriate verification and evidence.
• Produce high-quality engineering documentation, including design reports, system definitions and substantiation artefacts that support safety cases and regulatory submissions.
• Collaborate closely with internal teams and external stakeholders, including regulators, to resolve technical challenges and maintain programme momentum.
• Identify and actively manage risks and opportunities within the design scope, ensuring effective mitigation and continuous improvement.
• Apply design governance, configuration control and assurance processes to maintain consistency, quality and compliance.
• Provide technical leadership and guidance to engineers, supporting capability growth and driving a high-performance team environment.

What You’ll Bring

• Proved experience delivering complex system design work within nuclear or another highly regulated or safety-critical industry.
• A degree in an engineering or relevant technical discipline, or equivalent experience gained through industry delivery.
• Strong understanding of systems engineering principles, including requirements management, integration and structured design approaches.
• Practical experience in mechanical or process system design, such as fluid systems, HVAC, chemical or plant-based systems.
• Confidence in producing and reviewing detailed technical documentation such as P&IDs, calculations and design substantiation reports.
• Strong communication skills with the ability to engage and build credibility across multidisciplinary teams and stakeholders.
• A collaborative and proactive approach, with the ability to lead technical work, solve problems and support the development of others.

Location

This role is offered on a hybrid basis, with flexibility to be based in Derby, Warrington or Manchester. Regular onsite collaboration is expected, balanced with flexibility where possible.
