Mechatronics Engineer

Menlo•San Francisco, CA

About The Position

Menlo Research is an Applied R&D lab building Asimov, an open-source humanoid robot platform, and the full software stack that powers it. Our mission is to make humanoid labor economically viable, turning software into physical labor at scale. We build across the full stack: hardware architecture, locomotion, autonomy, simulation, and infrastructure. We move fast, ship to real robots, and open-source everything we can. If you want your work to matter beyond a paper or a demo, this is the place. We are looking for a Mechatronics Engineer to design and develop the systems that make Asimov move. You will work at the intersection of mechanical, electrical, and control engineering, taking subsystems from concept to working hardware. This is hands-on R&D: designing actuator and joint assemblies, integrating motors, sensors, and control electronics, prototyping fast, and iterating until it works on a real robot.

Requirements

Degree or equivalent hands-on background in mechatronics, mechanical, electrical, or robotics engineering
Strong design skills across mechanical and electrical domains, with real CAD proficiency
Experience taking hardware from concept through prototype to working system
Confident with actuator selection, motor control, and sensor integration
Comfortable reading and producing schematics, mechanical drawings, and system diagrams
Fluent in iteration: build, test, characterize, refine
Passionate about clean documentation and reproducible engineering

Nice To Haves

Experience designing for humanoid or legged robots
Familiarity with CAN bus communication and protocol analysis
Knowledge of torque specs, tolerance stacking, and structural integrity checks
Firmware or embedded control experience
Exposure to startup-paced product cycles

Responsibilities

Design and develop mechatronic subsystems: actuators, joints, drivetrains, and sensor integration
Select and integrate motors, encoders, sensors, and control electronics
Prototype rapidly, then test, characterize, and iterate toward production-ready hardware
Model and analyze mechanical designs for load, tolerance, and structural integrity
Bring up and debug systems across mechanical, electrical, and firmware layers
Work closely with controls, software, and hardware teams to close the loop from design to motion
Document designs, test results, and decisions clearly, tied to tickets or Linear workflows
Own subsystems end to end, from first sketch to working hardware on the robot
