Test Engineer

1X • Hayward, CA

8d • Onsite

About The Position

1X is building humanoid robots that work in any space humans exist with the mission to create an abundance of labor. This involves solving robotics, AI, software, hardware, manufacturing, and operations at the same time, at scale, in a form factor that has to be safe. NEO is their flagship general-purpose robot designed to move, learn, and operate in the real world alongside real people, and the company is shipping it. The Hands team is responsible for developing the robotic hands that allow NEO to interact with the physical world, spanning complex electromechanical assemblies, actuators, sensors, motor controls, structures, and embedded systems. As a Test Engineer on this team, you will build the test infrastructure to understand system behavior and prove robustness, capability, and readiness for real-world use. This is a highly hands-on role involving designing and building fixtures and test equipment, integrating instrumentation, writing test software, running tests, troubleshooting failures, and working directly with hardware.

Requirements

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Mechatronics, or a closely related engineering discipline, or equivalent hands-on experience.
• Demonstrated experience developing and integrating test systems for complex electromechanical products.
• Strong experience working with systems that combine sensors, electric motors, motor control electronics, wiring, structural components, and embedded control systems.
• Ability to write test software, develop test profiles, interface test controls with embedded hardware, and read or modify device-under-test software as needed.
• Experience working with telemetry and real-time signals for automated testing, diagnostics, closed-loop control, or issue detection.
• Hands-on experience with equipment such as data acquisition systems, power supplies, microcontrollers, wiring and relays, actuators, sensors, and custom test fixtures.

Nice To Haves

• Experience testing robotic hands, grippers, actuators, precision mechanisms, or other high-degree-of-freedom electromechanical systems.
• Experience developing automated fault detection, health monitoring, or telemetry-based diagnostics.
• Experience with long-duration, durability, or reliability testing.
• Experience with environmental testing, including thermal/humidity chambers or vibration testing.

Responsibilities

• Build the test systems and methods that prove NEO's hands and hand components perform reliably under real-world conditions.
• Own test infrastructure from requirements through execution: including fixtures, instrumentation, electrical interfaces, controls, software, data collection, and safety systems.
• Use these systems to validate hardware, analyze telemetry, identify failure modes, and turn test results into clear engineering decisions.
• Design and build end-to-end test systems for robotic hands and hand components, including fixtures, instrumentation, electrical interfaces, controls, software, and safety mechanisms.
• Translate engineering requirements into reliable test methods that exercise sensors, motors, motor control electronics, structural components, and complete hand assemblies under representative loads and operating conditions.
• Develop test software and control logic to configure test profiles, communicate with devices under test, collect telemetry, automate test progression, and detect issues in real time.
• Own tests from equipment bring-up through completion, including device integration, setup, monitoring, troubleshooting, inspections, and safe operation of test equipment.
• Analyze telemetry and instrumentation data to identify anomalies, failure signatures, and trends.
• Turn raw test data into concise reports that clearly communicate results, risks, and recommended next steps.
• Investigate failures quickly, reproduce unexpected behavior, and determine whether an issue originates in the test system or the product.
• Build reusable test software, instrumentation, and test architectures that improve validation coverage and increase engineering throughput as the hand program scales.

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
