Senior Test Development Engineer

About The Position

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. 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. 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 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. Test Engineering builds the systems that decide whether NEO hardware is ready to ship. We sit at the intersection of R&D, design, engineering and production. Developing the functional and end-of-line test stations that catch defects early, gate quality on the line, and turn production data into engineering action. As NEO scales into high-volume production, our work is what lets 1X grow without compromising quality.

Requirements

• Background in Electrical Engineering, Computer Engineering, Computer Science, Robotics, or equivalent practical experience.
• Proficiency in Python and/or C++, with willingness to work in both.
• Ability to read schematics and debug electronics at the board or subsystem level.
• Exposure to embedded systems, microcontrollers, or protocols such as CAN, SPI, I2C, UART, Ethernet, or EtherCAT.
• Hands-on experience with bench instrumentation (oscilloscopes, logic analyzers, multimeters, programmable power supplies).

Nice To Haves

• Building production test stations, end-of-line testers, hardware-in-the-loop systems, or test infrastructure.
• Robotics, electromechanical systems, motor controllers, sensors, actuators, batteries, embedded Linux, or real-time systems.
• Deploying and maintaining software across multiple production PCs or factory stations.
• Test-data pipelines, traceability, dashboards, WATS, MES, SQL, Splunk, or similar.
• Linux, Docker, Git, CI/CD, Bazel, remote deployment, or automated station management.
• AI-assisted development tools for faster software development, debugging, documentation, or fixture bring-up.

Responsibilities

• Develop and own test systems for NEO's electronics and robotic subassemblies as they move from design release into high-volume production.
• Own functional and end-of-line test stations for robot subassemblies (feet, head, battery, hands, arms, power boards) across their full lifecycle — requirements through deployment, maintenance, and corrective action.
• Ship operator-facing test apps with guided flows, clear pass/fail verdicts, robust error handling, and unit-level traceability.
• Improve station uptime, cycle time, test coverage, data quality, and deployment repeatability as production scales.
• Reduce escaped defects by reproducing and resolving failures across hardware, firmware, software, instruments, fixtures, and process — driving corrective action when stations or products fail.
• Connect results, serial numbers, board IDs, and logs into test-data systems so production data becomes actionable insight.

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
• Commuter benefits (transit and parking)
• Short-term and long-term disability, and life insurance
• Employee Assistance Program (EAP) for mental health, financial, and personal support
• Onsite snacks and catered lunches
