Senior Robotics Test Engineer

Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we’re growing the team to take it even further.

As a Senior Robotics Test Engineer at Humanoid, you will lead the testing, validation, and reliability assurance of advanced actuator systems, robotic mechanisms, grippers, and robotic hands used in our next-generation humanoid and manipulation platforms.

You will work closely with mechanical, electrical, and software engineers to develop robust test frameworks, build automated rigs, and execute functional, stress, and long-term validation tests to ensure our robots perform reliably under real-world conditions.

• Design, plan, and execute test procedures for actuators, mechanisms, grippers, and robotic hands.
• Build and maintain test fixtures and test rigs for dynamic and endurance testing.
• Develop automated test systems (hardware + software) to validate motor performance, force output, backdrivability, and safety limits.
• Conduct lifecycle, stress, thermal, and environmental tests on components and subsystems.
• Analyze test results, create test reports, and drive design feedback loops with engineering teams.
• Collaborate with design engineers to define testable requirements, tolerances, and performance metrics.
• Support incoming QC, assembly-level verification, and field failure diagnostics.
• Maintain test documentation, protocols, and results databases.
• Work closely with control and firmware teams to evaluate actuator behavior in closed-loop scenarios.

• Bachelor’s or Master’s degree in Mechanical, Mechatronics, Electrical Engineering, or related field.
• 3+ years of experience in robotic hardware testing, ideally in actuator or end-effector validation.
• Hands‑on experience with motor testing, force/torque sensors, encoders, and thermal monitoring.
• Familiarity with data acquisition systems (DAQ) and tools such as LabVIEW, Python, or MATLAB.
• Proficient with test automation frameworks and basic scripting (Python preferred).
• Comfortable with mechanical tools, instrumentation, and prototyping in lab environments.
• Strong understanding of safety testing, failure modes (FMEA), and reliability analysis.
• Excellent documentation, communication, and cross‑functional collaboration skills.

• Experience with robotic grippers and multi‑DOF hands (tendon‑driven, under actuated, or force‑controlled).
• Familiarity with torque control, backdrivable actuators, or custom brushless motor design.
• Knowledge of EtherCAT, CAN, or other motion communication protocols.
• Exposure to finite element analysis (FEA) or mechanical stress simulation.

• Comprehensive extended health benefits starting on your first day, including fully paid medical and dental, virtual care, employee and family assistance, and worldwide emergency medical support.
• Meaningful time off to rest and recharge: 23 days of annual leave (accrued), 15 days of paid sick leave, and paid company holidays.
• Equity included–we believe builders should share in what they build.
• Free daily catered lunch, snacks, and drinks in‑office.
• Collaboration with top‑tier engineers, researchers, and product experts in AI and robotics.
• Freedom to influence the product and own key initiatives.
