Senior Test Development Engineer
About The Position
1X is building humanoid robots designed to perform household chores and tasks, aiming to give people back their time. This involves solving complex challenges in robotics, AI, and manufacturing simultaneously, at scale, and in a safe form factor for home environments. The company has been working on this since 2014 and is now focused on shipping its flagship product, NEO, a home robot designed for real-world operation alongside people. The company is scaling and hiring intentionally, seeking individuals inspired by the mission to change how humans spend their time by creating abundance safely. The Test Engineering team is responsible for developing systems that ensure NEO hardware is ready to ship. They operate at the intersection of R&D, design, engineering, and production, creating functional and end-of-line test stations to identify defects early, maintain quality on the production line, and translate production data into engineering actions. As NEO production scales, the Test Engineering team's work is crucial for 1X's growth 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 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.
- 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.
- Drive corrective action when stations or products fail.
- Connect results, serial numbers, board IDs, and logs into test-data systems for actionable insight from production data.
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
