Test & Validation Engineer - Motors and Actuators

About 1X

1X is building humanoid robots designed to work in homes—handling chores and tasks to give people their time back. Since 2014, we've been solving robotics, AI, and manufacturing simultaneously at scale. Our flagship product, NEO, is a home robot designed to move, learn, and operate safely alongside real people. We're shipping it now.

About the Team

The Test & Validation team ensures systems powering NEO perform reliably in real-world conditions. We develop infrastructure, methodologies, and data that allow engineering teams to understand system performance, uncover weaknesses, and validate designs before production. Working across hardware, controls, firmware, and robotics teams, we provide objective evidence driving engineering decisions.

Your Role

As a Test & Validation Engineer, you'll own the characterization, testing, and validation of electric motors and robotic actuators that enable NEO's movement. You'll generate performance data, reliability insights, and validation frameworks ensuring actuator systems meet demanding requirements for efficiency, durability, safety, and real-world operation. You'll close the loop between design, implementation, and product performance, helping teams make faster, informed decisions.

Key Outcomes

• Deliver accurate, repeatable actuator and motor performance characterization across operating conditions and use cases
• Build and maintain scalable test infrastructure enabling efficient validation throughout development and production cycles
• Identify performance limitations, reliability risks, and failure modes early to influence design decisions and reduce program risk
• Provide high-quality test data and actionable insights improving actuator performance, efficiency, and robustness
• Support successful product releases through comprehensive validation
