We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not.

To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you’re inspired by this, you’ll thrive here. We’ve been at this since 2014 and we’re at the point where the hard problems are behind us and the hard work is in front of us.

NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it - we’re shipping it. We’re excited to meet you, if this excites you.

If you’ve spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We’re scaling, we’re hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.

About the Team

The Hands team builds the hands that let NEO grasp, manipulate, and help around the home. Packed with motors, encoders, gearing, and sensors, NEO’s hands are among the most dexterous and highest-cycle subsystems on the robot, and every one of them has to be proven before it ships.

Test engineering sits at the center of that work, from early bench characterization and design validation through production test and field returns. We partner closely with electrical, firmware, mechanical, and manufacturing engineering to make sure what we design is what we build, and that it keeps working.

Your Charter

Build and own the tests that prove NEO’s hands work. You will develop the test software, stations, and procedures that characterize hand actuators and sensors, catch failures early, and keep production moving with confidence.

As a Hardware Test Engineer, you’ll bridge the bench and the production line, understanding what each test is actually measuring, turning raw data into clear root causes, and building tests that technicians can run reliably at scale.

Key Outcomes

Build automated pass/fail test scripts that log data and generate plots to characterize hand actuators, encoders, and sensors with repeatable, trustworthy results

Own and maintain test PCs and production stations, keeping them healthy, networked, and running validated software

Turn failures into answers by pulling logs, pinpointing the moment a failure happened, and writing clear root-cause summaries that drive design and process fixes

Write repeatable procedures and build tests that technicians can run safely and consistently on live production equipment

Design and build test fixtures and jigs that speed up validation of hands, grippers, and high-cycle actuators

Key Competencies

Strong electromechanical intuition with a clear understanding of what a test is actually measuring, not just how to run it

Rigorous, data-driven debugging with the ability to trace a fault from a log or waveform back to its source in hardware, firmware, or the test itself

Production mindset: careful with live equipment, disciplined about procedures, and focused on repeatability

Strong cross-functional collaboration skills and comfort working across hardware, firmware, and software boundaries

Ownership mindset with a bias toward execution, accountability, and continuous improvement

Minimum Requirements

Bachelor's degree in Electrical Engineering, Mechanical Engineering, Mechatronics, Computer Engineering, or a related field

5+ years of professional experience in hardware test, validation, or manufacturing test engineering

Experience writing software for test and test automation, including pass/fail test scripts, data logging, and plotting

Strong electromechanical fundamentals: motors (FOC basics, torque, current, back-EMF), encoders, gearing, and friction

Comfort working in Linux, including SSH, process and service management, and troubleshooting disks and networks

Hands-on bench experience with oscilloscopes, multimeters, power supplies, thermocouples, load cells, wiring, and fixturing
