Mechanical Engineer, Dynamometer and Actuator Testing Infrastructure

Have strong intuition for load paths, stiffness, alignment, rotating machinery, and the practical behavior of real hardware.

Enjoy designing fixtures and structures that are precise, robust, safe, and easy for others to use.

Are highly hands-on and comfortable assembling, aligning, instrumenting, and debugging test equipment.

Can move fluidly between first-principles analysis, CAD, vendor collaboration, and lab iteration.

Care about details such as tolerances, runout, resonance, thermal growth, guarding, and serviceability.

Are comfortable working in fast-moving environments with evolving test needs and aggressive technical goals.

Take ownership of the full test-stand lifecycle, from concept through reliable daily operation.

Communicate clearly across mechanical, electrical, controls, software, safety, and operations teams.

Are motivated by building infrastructure that reveals how advanced robotic actuators really perform.

Are excited to build mechanical test infrastructure that accelerates robotic actuator development.

Preferred qualifications

Bachelor’s or graduate degree in Mechanical Engineering, Robotics, Mechatronics, or a related field.

Experience designing mechanical systems for robotic actuator dynamometers, robotics, automation, rotating machinery, aerospace, automotive, or similar high-performance hardware.

Strong understanding of structures, load paths, shafts, bearings, couplings, fasteners, tolerances, alignment, and vibration.

Experience designing fixtures, test stands, frames, guarding, and precision mechanical interfaces.

Proficiency with CAD and drawing release workflows; NX, SolidWorks, Creo, or equivalent experience is welcome.

Experience with structural, thermal, fatigue, or modal analysis and applying results to practical hardware decisions.

Hands-on experience with assembly, machining, metrology, alignment, and troubleshooting in a lab or prototype environment.

Familiarity with mechanical safety for rotating equipment, containment, interlocks, and safe operating envelopes.
