Ready to ScanRole Overview
As an Actuator Test Engineer on our team, you will build the dynamometer test infrastructure to verify how every actuator we put on the robot actually performs.
You will move fluidly between designing test fixtures, building test stands, and running the characterization tests that drive our actuator selection and sizing decisions.
Full Job Posting
Responsibilities
- Design and build the dynamometer test systems, including mechanical driveline, load application, and sensor integration (torque, position, thermal).
- Design and fabricate test fixtures and stands for actuator, gearbox, and driveline validation, producing accurate 2D drawings with GD&T (ASME Y14.5) for tight tolerances and proper fits.
- Run tests on actuators to characterize torque, speed, efficiency, thermal performance, stiffness, friction, bandwidth, life-cycle, backlash, and torque sensor accuracy.
- Support electromechanical integration of motors, encoders, torque sensors, and other components onto test rigs.
- Generate and visualize the data that drives actuator selection and sizing decisions
- Build repeatable test procedures and data pipelines that scale from a single actuator on a bench to characterizing units across the fleet.
- Quantify unit-to-unit variation, track drift and wear over time, and flag outlier units.
- Perform post-test teardown inspections (gear wear, bearing wear, lubrication condition, wiring/sensor integrity) and document findings rigorously.
Qualifications
- 3+ years of hands-on experience testing and characterizing real electromechanical or robotic hardware.
- Demonstrated ability to design and build test hardware such as fixtures, stands, and drivelines from concept through fabrication.
- Proficiency with 3D CAD and the ability to generate 2D drawings with GD&T per ASME Y14.5.
- Solid grasp of actuator fundamentals: motors, gear transmissions (planetary, harmonic/strain-wave, cycloidal), encoders, torque/force sensors, and thermal behavior.
