## Description

Role Title: Engineer - Plant PerformanceWe 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 Performance & Analysis team is the centre of excellence for engineering analysis used to substantiate the performance and safety of the SMR power station. Within this team, Plant Performance Engineers play a vital role in understanding how the power station behaves under normal operation and transient conditions, ensuring that performance assumptions are robust and design decisions are well-informed.About the Role:As an Engineer - Plant Performance, you will analyse the whole-plant performance of the nuclear power station, covering the complete energy conversion system-from heat generation in the reactor, through the steam and power-conversion cycle, to cooling systems and electrical power generation.You
will independently plan and deliver plant-performance analysis work packages under established governance and quality processes. This includes assessing steady-state performance, analysing transient behaviour, developing and maintaining analysis models, and supporting validation and benchmarking activities.Your outputs will support periodic plant-performance assessments aligned with design iterations across the programme, providing validated performance data that feeds into system and component design. You will also contribute to the development of probabilistic performance methods to support uncertainty analysis and robust design practices.This role requires close collaboration with design, safety, systems and wider engineering teams, clear communication of technical results, and flexibility to support an evolving design programme.We'll Need You To:Analyse plant performance under steady-state and transient operating conditionsDeliver periodic plant performance assessments aligned with
design maturityDevelop, apply and maintain plant-performance analysis models, methods and toolsAssess thermodynamic behaviour of the power station and its supporting systemsSupport validation of plant-performance assumptions and provision of functional design dataDevelop probabilistic performance assessment methods to support uncertainty analysisApply robust quality processes, supporting verification, validation and benchmarking activitiesPlan and manage your own technical workload to meet programme objectives and schedulesCollaborate across multidisciplinary engineering teams to define analysis requirementsCommunicate analysis results clearly to technical and non-technical stakeholdersKey Skills Required:We know there's no such thing as the 'perfect' candidate. If you meet around 75% of the criteria below, we'd love to hear from you:Strong understanding of thermodynamic performance and energy-conversion systemsExperience applying structured and methodical approaches to performance
