Job Description

Traction Battery Cooling and Thermal Engineer
Job Description
The traction battery cooling and thermal engineer emphasises analysis and optimising the performance of traction battery modules fitted to train vehicles. The traction battery cooling and thermal engineer will be responsible for the development of technical requirements, synthesis, and analysis of them by and with suppliers, and overall verification during the complete design cycle in battery packs for the traction battery programme. Where these tools are insufficient or do not exist, you will develop novel methodologies to enable fast and accurate solutions.
Roles and Responsibilities:

  • Delivering CAE and CFD support by creating cutting-edge FE and CFD models down to the smallest details.
  • Facilitate efficient CAE and CFD simulations to analyse and improve subsystems and whole product simulations of specific design features and manufacturing processes.
  • Manage and negotiate essential interfaces between the vital energy storage system and various vehicle subsystems such as charging, electrical, thermal, traction controls, vehicle structure, etc.
  • High level of expertise in single and multi-phase CFD, thermal, coupled electrical, and thermal CAE. Develop and employ analytical tools for functional verification of battery systems.
  • Design and implement subsystem-level and train level vehicle correlations in accordance with railway standard standards and best practices.
  • Conduct post-test assessments and compare the CAE and CFD projections to the test outcomes.
  • Provide technical assistance in examining system problems and support for root cause analysis, mitigation, and corrective action plans.
  • Develop a system DFMEA and risk mitigation plans for high-risk items.
  • Conduct optimisation studies on components, assemblies, or vehicle designs using optimisation methods such as DOE/ DFSS methodologies to satisfy performance goals while adhering to mass and cost limitations. Create highly predictive models of materials and processes that can be correlated with physical tests. Keep up to date with battery industry trends, product benchmarks, technologies, and designs.


  • Minimum of HND level Engineering qualification to be considered for this role
  • Preferably Chartered engineer or working towards Chartership
  • Minimum of 5 years in product engineering design and development in automotive or railway/automotive industry with 3 years working as experience with HV battery design and optimisation
  • Deep knowledge of Finite Element Analysis, Finite Volume Method, Smooth Particles, hydrodynamics, CFD, and Numerical methods within product development
  • Preferred experience in stand-alone or coupled analysis of electronic components for thermal, fluid mechanics, electromagnetism, and structural.
  •  Preferred experience in analysing coupled thermal-electrical problems, fluid flow through vehicle bodies, and electronics cooling.
  • Demonstrated ability to deconstruct complex test scenarios with sound logic and analytics and root-causing correlation problems.
