Senior Simulation Engineer

Role Title:Senior Simulation Engineer
Ref. No.SP-RRF-100
Reporting to:Chief Engineer, HV Drive Systems
Role Purpose:As a Simulation Engineer within Sprint Power, you will be central to the design and development of new propulsion concepts. An agile, highly capable engineer is needed to implement an integrated simulation approach to address the electrical, thermal and mechanical design challenges of propulsion system and sub-systems such as battery, fuel cells, power electronics and electric motors. The role involves using a range of simulation tools to support the design and analysis of cooling systems, provide thermal management solutions or predict the performance of vehicle and sub-system (e.g., battery pack) through 1D simulation.

Key Aspects of the role

  • Promote the System Engineering and Digital Twin approach for propulsion system engineering and enable continuous process improvement
  • Perform 1D thermal simulation and provide thermodynamics analysis based on simulation result to support the design and development of client or internal R&D projects.
  • Produce accurate analysis for thermal management of propulsion system and sub-systems (e.g., battery, power electronics and electric motors) or xEV using hand calculations (Excel based) or 1D thermal simulation
  • Build and calibrate the thermal models of propulsion system and sub-systems
  • Responsible for propulsion system and components thermal performance requirements, product validation plans, and delivering validation tasks
  • Use a range of simulation tools to build the vehicle or propulsion system models that can be used to predict performance, such vehicle energy/fuel consumption, EV range and battery heat rejection, or as plant models for MIL (Model-in-the-loop) and HIL (Hardware-in-the-loop) for Software team
  • Manage and perform simulation (or co-simulation) to optimise powertrain components sizing and energy management strategies by using Design of Experiments (DoE) and optimisation
  • Interpret vehicle level requirements into propulsion system and sub-system (e.g., battery, power electronics and electric motors) requirements using hand calculations (Excel based) or 1D simulation
  • Improve propulsion system components (e.g., battery, power electronics and electric motors) and xEV modelling, simulation, and digital engineering toolchains
  • Apply a system engineering approach, translating customer requirements into design use cases and sub-system targets
  • Work closely with testing engineers to validate the design proposal and ensure the learning is cascaded into future models
  • Create project documentation in line with company processes and standards
  • Present analysis findings in technical reviews and make clear recommendations
  • On site working at the Clients facilities may be required

Qualifications, Experience, Skills, and Knowledge


  • A degree or similar qualification in an Engineering, Physics, or science-based subject that covers heat transfer and fluid dynamics with experience of simulation at an OEM or Tier 1
  • Technical background or interest in thermodynamics, with some experience of analysis of thermal systems, ideally within the automotive industry
