Role Title: Senior Simulation Engineer
Locations: Hybrid working with one of the following locations as your primary site: Derby, Manchester or Warrington
We anticipate paying a salary between £48,000 - £63,000 DOE.
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.
We are now recruiting for a Senior Simulation Engineer, to be involved in industry leading, cutting-edge design project for a new type of power station.
What You’ll Be Doing
The Performance & Analysis team is the centre of excellence within Rolls-Royce SMR for the engineering analysis used to prove the performance and safety of the power station.
The team are building whole-plant Engineering Simulators as part of their strategy, utilising Simulation Assisted Engineering for use cases spanning all aspects of design and development.
Reporting to the Simulation Development Manager, you will be involved in the development, validation and verification of software simulation models of nuclear power plant and C&I systems using suitable modelling tools and software validation and verification techniques.
You will support the integration of simulation models within the overall simulation model architecture and the integration of the software simulation models with hardware simulation facilities. The simulation model will be used to support design activities, analysis campaigns, verification programmes, validate C&I systems, and train operators.
You will support the development of the modelling and simulation environment, policies, procedures, and tool sets, and support the definition of hardware simulation facilities and processes and tools for integration.
The Key Responsibilities Will Include
