What to Expect
We are building a general-purpose humanoid robot from the ground up, and thermal performance is a hard constraint - not an afterthought. As aRoboticsThermal Design Engineer, you will own the thermal design and analysis of joint actuator and controller subsystems, from early concept through hardware validation and into production. You will work at the intersection of mechanical, electrical, andcontrolsengineering, ensuring that actuatorsoperatereliably across all mission profiles and duty cycles in a highly constrained form factor.

What You'll Do
  • Own the end-to-end thermal design and analysis for jointactuatorand embedded controller assemblies, from concept through production
  • Develop andmaintainsteady-state and transient thermal models (CFD/FEA) and correlate them with data from physical hardware tests
  • Define thermal requirements, margins, and derating curves in collaboration with mechanical, power electronics, and firmware teams
  • Conduct hands-on thermal characterization of hardware using thermocouple instrumentation, IR thermography, and calorimetry
  • Select and qualify thermal interface materials, potting compounds, and adhesives for demanding mechanical and environmental conditions
  • Identifyand communicate thermal risks early in the design cycle, driving mitigations across current and future platforms
  • Support design reviews, DVT/PVT builds, and failure analysis for thermal-related issues

What You'll Bring
  • DegreeinMechanical Engineering orarelated field, or equivalent experience
  • Strong fundamentals in heat transfer - conduction, convection, and radiation - applied to real hardware in constrained form factors
  • Proficiencyin CFD/FEA thermal simulation tools (AnsysIcepak, Fluent, COMSOL, or equivalent) anda track recordof correlating results to physical test data
  • Experience with thermal management of power electronics - PCB-level heat spreading, TIM selection, heatsink and housing interface design, junction temperature estimation
  • Comfortable working in a fast-paced, hardware-iterative environment where designs evolve quickly and ambiguity is the norm
  • Strong cross-functional communication skills -you'llregularly workacross mechanical, electrical, firmware, and manufacturing teams
  • Advanced degrees preferred
