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.

About the Work

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

Test Development & Execution

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

Continuous Improvement & Technical Leadership

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

About You

Experience:

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

Technical Expertise:

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

Proficiency in python scripting for test automation

Skills:

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.

Education:

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