We always wanted to be more than just a place to work. What we do and how all of our team members feel is meaningful to us and we want each to feel like part of a big family.

 

We are looking for a Thermal Systems Engineer focusing on electric vehicle sub-system and system thermal performance.

In this role you will be responsible for thermal aspect of an electric powertrain, from collecting the data, preparing the simulation models and performing simulations, to the analysis of numerically and experimentally obtained data.

You will interact with multiple departments to develop, improve and optimize thermal systems from component to the full vehicle level.
For this position you must be passionate about physics, thermodynamics, but also you should be passionate about cars, technology and solving of complex engineering problems.

 

1. Responsibilities

  • Prepare, perform and analyse thermal system simulations using 1D tools.
  • Build and develop 1D simulation model at full vehicle level with emphasis on powertrain heat transfer, aerodynamics, vehicle dynamics and control logic.
  • Integration of vehicle sub-systems into a larger system level simulation models.
  • Coupling between various 1D models from different departments or suppliers.
  • Suggest improvements on design, processes and methods.
  • Interact with other departments or suppliers to collect input data for simulation and model building.
  • Provide suggestions and improvements after analyzing simulation or experimental data.
  • Mentor less experienced engineers.
  • Write technical documents, prepare presentations and communicate the results to higher leadership.

 

2. Requirements

  • Full understanding of electric vehicle thermal management concepts, including flow architecture, heat rejection methods, cooling system components (heat exchangers, pumps, valves, sensors, …)
  • 4+ years of experience in automotive powertrain cooling systems development
  • A strong grasp of Fluid Dynamics, Thermodynamics and Heat Transfer.
  • Good level of programming knowledge in relevant 1D tools to vary control parameters of components such as inverters, batteries and electric motors.
  • Proven analytical abilities with some of the following modeling tools: MATLAB and Simulink, GT-SUITE, Dymola, AVL or AMESim.
  • Your commitment to project plan and deliverables.
  • Good communication and organization skills.
  • Good knowledge of English (written and spoken)

 

3. Considered as an advantage

  • Coupling of 1D and 3D CFD simulations
  • Sub-system and system level testing experience
  • Experience with thermal control logic design and testing
  • Good programming skills and previous experience with C++, MATLAB, Python, Linux
  • CAD knowledge (3D Experience/CATIA – preferable)

 

 

4. What we offer

  • The opportunity to develop world-class solutions with cutting-edge technology, from scratch!
  • Family-like and open work environment
  • Courageous, curious and entrepreneurial team members to work with
  • Competitive compensation package
  • Financial support for accommodation and transportation
  • Dog-friendly office
