Thermal Engineer, Robotic Actuators

The role

You will develop cooling solutions for compact robot actuators with a focus on liquid cooling. You will own thermal models and cooling-system design and validate them on working hardware.

What you will do

• Translate motor and inverter losses and robot duty cycles into thermal requirements, boundary conditions and operating limits.
• Develop conjugate heat-transfer and CFD models alongside reduced-order thermal models.
• Correlate models to instrumented hardware.
• Design cold plates, stator jackets and heat paths.
• Specify coolant flow, pressure drop, pump operating points and system heat-rejection needs.
• Develop coolant routing through moving joints with mechanical engineers.
• Plan and run thermal characterization across ambient conditions and transient duty cycles.
• Diagnose hot spots and validate design changes.
• Provide measured thermal limits and model inputs to drive and firmware engineers for derating behavior.
• Support supplier and manufacturing validation.

Required qualifications

• Hands-on thermal design and test experience with liquid-cooled electromechanical or power-electronics systems.
• Strong fundamentals in heat transfer, fluid mechanics, pressure-drop analysis and thermal resistance networks.
• Experience with conjugate heat-transfer or CFD tools such as Ansys Fluent, Star-CCM+ or equivalent.
• Experience with thermal-network modeling and experimental correlation.
• Ability to design practical cooling hardware.
• Ability to use thermocouples, flow and pressure measurements, or equivalent instrumentation to validate it.

Nice to have

• Experience cooling motors, EV batteries, inverters, servo drives or compact robot joints.
• Experience with moving coolant lines, compact sealing interfaces, leak testing or coolant material compatibility.
• Experience with Motor-CAD thermal or equivalent reduced-order models, thermal test automation or manufacturing processes for cooling components.
