FEA Simulation Engineer, Thermal | Actuation & Simulation

About 1X
We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general-purpose robots capable of performing any kind of work autonomously.

We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That’s why we’re focused on developing friendly home robots designed to integrate seamlessly into everyday life.

We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey.

Role Overview
As a Thermal FEA Simulation Engineer, you will ensure that actuators and embedded systems meet performance and safety requirements under thermal constraints. You will develop high-fidelity thermal models, perform simulations, and validate designs through testing. Your work will be instrumental in optimizing heat management and enabling reliable, high-performance operation of NEO, our humanoid robot.

Responsibilities

• Build high-fidelity 3D thermal models of actuators, including electric motors, power electronics, and mechanical housings

• Simulate and analyze thermal behavior to identify areas for risk mitigation and performance optimization

• Develop and implement design improvements to manage heat across compact and integrated assemblies

• Run thermal validation tests at subsystem and full product levels, correlating simulation results with experimental data

• Collaborate with electrical, mechanical, and systems teams to implement and verify thermal solutions in hardware

• Bachelor’s or Master’s degree in Mechanical Engineering, Electrical Engineering, or a related field

• 3+ years of experience with FEA thermal analysis and modeling of electro-mechanical systems

• Proficiency with thermal simulation tools (e.g., ANSYS, COMSOL, or similar)

• Strong understanding of heat transfer mechanisms including conduction, convection, and radiation

• Experience validating simulations with experimental test data

• Ability to collaborate effectively across cross-functional engineering teams

Benefits & Compensation

• Salary Range: $94,906 – $244,076

• Health, dental, and vision insurance

• 401(k) with company match

• Paid time off and holidays
