Full Job Description
The Role
We are looking for a Thermal Engineer to develop cooling solutions for compact robot actuators, with a focus on liquid cooling. You will own thermal models and cooling-system design, then validate them on working hardware. You will work across motor, drive and mechanical design to sustain performance over realistic robot duty cycles. Responsibilities
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 them to instrumented hardware.
Design cold plates, stator jackets and heat paths, and specify coolant flow, pressure drop, pump operating points and system heat-rejection needs.
Develop coolant routing through moving joints with mechanical engineers, accounting for motion, serviceability, sealing, compatibility and leakage risks.
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.
Minimum 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, plus thermal-network modeling and experimental correlation.
Ability to design practical cooling hardware and use thermocouples, flow and pressure measurements, or equivalent instrumentation to validate it.
Preferred Qualifications
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.
