Role Title: Lead Control & Instrumentation (C&I) Architect Engineer We are Rolls-Royce SMR and 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. The Control & Instrumentation (C&I) team is responsible for delivering safe, secure and technically robust control, protection and monitoring systems across the power station. These systems underpin reactor safety, plant operation, and the integration of safety‑classified and non‑classified systems. The C&I Architecture function ensures design coherence, independence, separation, interface integrity and clear functional allocation across the entire station. About the Role As a Lead C&I Architect Engineer, you will define the overall C&I architecture for the Rolls‑Royce SMR power station. You will act as the technical authority for architectural decisions, ensuring independence, separation and segregation principles are applied correctly across all C&I systems. You will maintain oversight of the full architectural landscape, ensuring consistency across the reactor, conventional and cooling water islands. The role includes leading the development and management of key architectural deliverables such as the overall C&I architecture model (Capella) and system‑level design descriptions. You will support functional integration with plant‑wide architecture, systems engineering, safety and project integration teams—ensuring that interfaces remain aligned, cross‑cutting requirements are robust, and design updates flow cleanly through the lifecycle. This role is ideal for someone who enjoys shaping nuclear‑grade system architectures, solving complex engineering challenges and guiding cross‑functional teams towards a unified, verified design vision. We’ll Need You To: Lead the definition and development of the overall C&I architecture for the SMR Guide major design decisions using principles of independence, separation, and segregation Maintain architectural consistency across reactor island, conventional island and cooling water systems Own and manage key C&I architectural deliverables including the architecture model and design descriptions Collaborate with plant architecture, systems engineering, safety case, and project integration teams Support the development and maintenance of functional interfaces and cross‑cutting C&I system requirements Ensure architectural updates are correctly captured and propagated across the design lifecycle Apply relevant industry standards and nuclear‑grade design principles in all architectural decision‑making Provide technical leadership to C&I teams and mentor engineers contributing to architecture workstreams Lead design reviews and contribute to verification and validation of architectural decisions Support internal and external stakeholder engagement including safety, assurance and regulatory discussions Key Skills Required We know there’s no such thing as the ‘perfect’ candidate. If you meet around 75% of the criteria below, we would love to hear from you: Significant experience across the systematic design lifecycle of C&I systems including specification, design, assessment, verification, testing, installation, commissioning and maintenance Deep understanding of designing functionally resilient systems, including independence, segregation and diversity principles Broad knowledge of C&I technologies, digital platforms, protection systems, instrumentation and software/hardware architectures Strong experience applying industry standards such as IEC 61508, IEC 61513, IEC 61226 or equivalents from other safety‑critical sectors Demonstrable experience applying systems engineering methodologies, including requirements management, interface management, decision analysis and structured verification Experience using MBSE tools (Capella preferred) and requirements tools (e.g. DOORS, Polarion) Ability to translate high‑level plant requirements into functional and logical C&I architectural designs Strong communication and presentation skills, able to articulate complex system interactions clearly Ability to build strong relationships with engineering, safety, security, suppliers and regulatory stakeholders Experience providing technical leadership, coaching teams and guiding architectural decisions Ability to evaluate technologies and understand how systems and components interact within a nuclear‑grade environment Degree‑qualified in electrical, control, instrumentation or systems engineering, or equivalent experience We welcome applicants from a wide range of backgrounds, including nuclear and other high‑integrity sectors.
