Responsibilities

  • ● A strong team is the DNA of our company.
  • ● In this role, you own the thermal architecture of the vehicle: battery cooling and heating, power electronics and e-motor cooling, cabin climate, and the coolant and refrigerant circuits that connect them. You size these systems, design and integrate the mechanical hardware (pumps, valves, heat exchangers, lines and mounts) and make sure they work together across the full operating range, from alpine winters to fully loaded summer duty cycles.
  • ● You work closely with our mechanical, electrical and software teams. You define the thermal requirements and operating strategy together with software, and support development from concept through simulation and calculation to verification in the vehicle and in the field.
  • ● At Flux, you will work in a small team with short decision-making paths. You take ownership of technical decisions early and directly shape the architecture of our vehicles.
