Senior Hardware Test Engineer

We are seeking a Senior Hardware Test Engineer with 5+ years of experience to join our team in the San Francisco Bay Area. In this hybrid role, you will serve as a key technical leader for design verification testing of the humanoid robots arm subsystem and components including electronics, electrical interfaces, actuators, sensors and end-effectors.

You will own verification strategy and planning, develop robust test infrastructure, lead subsystem-level characterization, and drive improvements in test coverage, engineering rigor, and design robustness.

- Own the design verification strategy for the arm subsystem and components, including electronics, electrical interfaces, actuators, sensors, and end-effectors

- Define verification plans, coverage goals, and test protocols across the product development lifecycle

- Partner with hardware design, systems engineering, and analysis teams to ensure requirements, testability, and verification readiness are addressed early in development

- Maintain clear end-to-end traceability from subsystem requirements through test execution and results

- Develop and execute subsystem-level characterization and design verification testing for torso electronics

Design automated, repeatable test setups for electrical interfaces, actuators, sensors, end-effectors, and control electronics

- Build test scripts, tooling, and diagnostics to improve efficiency, repeatability, and data quality

- Lead investigation of verification test failures and nonconformances, driving root cause identification and corrective actions in partnership with design teams

- Identify gaps in verification coverage and implement improvements in test infrastructure, processes, and standards

- Document test methods, results, and best practices to scale learning across future development cycles

- Mentor junior engineers and foster a culture of strong engineering rigor, execution, and continuous improvement

- Minimum of 5 years of experience in test engineering, design verification, or electrical validation

- Strong preference for experience in robotics, autonomous vehicles, aerospace, or other complex hardware systems

- Deep understanding of mechatronics verification testing, including motor controllers, electrical interfaces, kinematics and sensors with a strong preference for experience with EtherCAT architecture

- Experience validating electro-mechanical systems, and safety-critical electrical subsystems

- Familiarity with sensor verification (force torque, motor encoders) and performance characterization

- Proficiency with lab tools such as oscilloscopes, sensors, logic analyzers, DAQs, power supplies, and environmental test equipment

- Strong analytical and troubleshooting skills, with the ability to translate test results into clear design feedback

- Exceptional communication and collaboration abilities, capable of driving alignment and leading technical discussions across multidisciplinary teams and supplier partners

- Demonstrated ability to execute effectively and drive results in dynamic, highly ambiguous environments.

- Bachelor's degree in Mechatronics, Controls, Electrical Engineering, Computer Engineering or a related field (Master's preferred
