Role Title: Manager – RI Safety Systems (Fluid Systems) 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 Reactor Safety Systems team is responsible for the design and delivery of safety‑critical plant systems that protect reactor and fuel integrity across all operating and faulted conditions. This is a unique opportunity to lead the development of key fluid‑based safety systems that sit at the heart of the nuclear safety case. About the Role: Three positions are currently available for RI Safety Systems Managers, each leading the development of technical solutions within one of the following critical safety system areas: Spent Fuel Pool (SFP): Safety and duty systems including fuel‑pool cooling, inventory and purification systems, faulted fuel‑pool cooling and fuel‑pool boil‑off scenarios Low Temperature Decay Heat Removal (LTDHR): Class 2 systems including cold shutdown cooling, component cooling and essential service water systems and the associated cooling chain Emergency Core Cooling (ECC): Class 1 passive safety systems including Automatic Depressurisation Systems, Low Pressure Injection Systems, In‑Containment Water Storage Systems, Local Ultimate Heat Sink Systems and containment sump systems In each case, you will lead a team of System Design Engineers through the full design lifecycle, progressing systems through gated design review cycles from concept through into detailed design. The majority of systems within the department are now entering the detailed design phase, building on established concept definitions. This role will therefore require both strong conceptual design thinking and the ability to mature systems through into fully defined, deliverable engineering solutions. We’ll Need You To: Lead a team of engineers through system design progression and gated review cycles Deliver technically robust and fully substantiated designs for safety‑critical fluid systems Own design outputs across requirements, architecture, analysis and definition Take full line‑management responsibility, including coaching, mentoring and pastoral care Support senior leadership in growing team capability and delivery capacity Manage delivery of complex design programmes within a fast‑paced environment Define, manage and verify system requirements in line with systems‑engineering principles Apply structured lifecycle design approaches including: Requirements capture and validation Optioneering and decision‑making Design development under configuration control Ensure design compliance with environmental, safety, security and safeguarding requirements Oversee production and review of key technical artefacts such as: Design descriptions P&IDs Requirements specifications Optioneering and decision records Lead multidisciplinary engagement to resolve complex system‑level challenges Operate effectively under ambiguity, making sound engineering decisions and managing stakeholder expectations Key Skills Required: We know there’s no such thing as the ‘perfect’ candidate.
