Mechatronics Engineer
About Menlo
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.
The Role
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.
What You'll Do
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
What We Look For
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 Have
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
Why Join Menlo
You will be part of a tight-knit team defining the next generation of humanoid robots. With genuine ownership of the systems you design and the freedom to innovate, you will see your work come to life in real-world deployments. If you thrive in fast-paced, open, collaborative environments, let's build the future of robotics together.
A Note on AI
You don't need deep AI expertise for every role, but we do expect everyone at Menlo to be intellectually curious, drawn to tinkering and discovery, and excited to use AI as a real collaborator in their work. For some roles, AI fluency is a core requirement. When that's the case, we'll say so explicitly in the qualifications. People who thrive here don't treat AI as a novelty. They use it to think better, and make their work easier for others to build on.
Equal Opportunity and Accommodations
We hire talented people from a wide range of backgrounds. If you're excited about a role but don't meet every bullet, we still encourage you to apply. Menlo Research is an equal opportunity employer and does not discriminate on the basis of any legally protected characteristic. Menlo provides reasonable accommodations during the application process. If you need one, please let your recruiter know.
