Description

  • Own the thermal roadmap for the humanoid robot platform and define cooling strategies for high-torque actuators and high-density compute enclosures.
  • Develop high-fidelity CFD and heat transfer models using industry-standard simulation tools.
  • Model transient thermal behavior during dynamic robot activities such as walking and lifting.
  • Collaborate with structural simulation engineers on fluid-structure interaction and thermal-stress analysis for critical components.
  • Design and lead physical thermal validation experiments and correlate test data with simulation results.
  • Use IR thermography, thermocouples, and flow sensors to validate thermal models.
  • Work with the DfX team to select materials and thermal management components that balance performance, weight, and cost.
  • Serve as the company-wide subject matter expert for thermal issues and mentor junior engineers.
  • Establish standardized thermal design rules and support thermal architecture decisions from the concept phase.

Requirements

  • 8+ years of experience in thermal design and simulation for high-performance electromechanical systems such as robotics, EV, aerospace, or high-end computing.
  • Expert-level proficiency in CFD software.
  • Deep understanding of conduction, convection, and radiation in complex assemblies.
  • Proven track record of designing and shipping hardware with challenging thermal constraints.
  • Experience with embedded compute thermal management or high-flux motor cooling is a significant plus.
  • Ability to perform back-of-the-envelope thermal calculations to guide early design decisions.
  • BS or MS in Mechanical Engineering, with a PhD preferred.
  • Focus or specialization in heat transfer or fluid dynamics preferred.
  • Must be able to lift 15 pounds at times and meet basic physical requirements for desk and computer work.
