Mechatronics Engineer

About MenloMenlo 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 RoleWe 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 DoDesign and develop mechatronic subsystems: actuators, joints, drivetrains, and sensor integrationSelect and integrate motors, encoders, sensors, and control electronicsPrototype rapidly, then test, characterize, and iterate toward production-ready hardwareModel and analyze mechanical designs for load, tolerance, and structural integrityBring up and debug systems across mechanical, electrical, and firmware layersWork closely with controls, software, and hardware teams to close the loop from design to motionDocument designs, test results, and decisions clearly, tied to tickets or Linear workflowsOwn subsystems end to end, from first sketch to working hardware on the robotWhat We Look ForDegree or equivalent hands-on background in mechatronics, mechanical, electrical, or robotics engineeringStrong design skills across mechanical and electrical domains, with real CAD proficiencyExperience taking hardware from concept through prototype to working systemConfident with actuator selection, motor control, and sensor integrationComfortable reading and producing schematics, mechanical drawings, and system diagramsFluent in iteration: build, test, characterize, refinePassionate about clean documentation and reproducible engineeringNice to HaveExperience designing for humanoid or legged robotsFamiliarity with CAN bus communication and protocol analysisKnowledge of torque specs, tolerance stacking, and structural integrity checksFirmware or embedded control experienceExposure to startup-paced product cyclesWhy Join MenloYou 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 AIYou 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 AccommodationsWe 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.
