Software Engineer
Mechanical Engineer focused on designing, analyzing, and validating structural and kinematic systems for Asimov, Menlo’s open‑source humanoid robot. Works across hardware architecture, locomotion, and simulation to deliver robust, manufacturable robot components.
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
As a Mechanical Engineer, you will own the design, analysis, and validation of the structural and kinematic systems that make Asimov move. You will take components from concept through production-ready hardware -- working across joints, actuators, enclosures, and structural members -- ensuring every design holds up mechanically and integrates cleanly with the broader electromechanical system.
What You'll Do
Design and develop mechanical assemblies across the full humanoid body, including joints, actuators, sensor mounts, and structural members
Develop detailed 3D part, drawings and assembly models across plastics, metal, and composite materials in Solidworks or equivalent CAD tools
Run hands-on test rigs: load testing, fatigue cycling, thermal soak, and kinematic validation across body segments
Execute DFM reviews alongside contract manufacturers, going to the floor to understand tooling constraints, cycle times, and failure modes firsthand
Create and maintain production drawings with GD&T and inspection callouts for handoff to CMs and QA
Set up and instrument test stands, wire sensors, and collect data to analyze failure modes and close the loop on design iterations
Work across plastics, metals, and composites, selecting materials and joining methods appropriate for the loading conditions and production intent
Coordinate with firmware and electrical teams to physically integrate actuators, sensors, and PCBs into mechanical assemblies, ensuring cable routing, connector access, and serviceability are accounted for
Contribute to Menlo 's open-source hardware releases, including build guides, BOM documentation, and assembly instructions for the communityContribute to Menlo 's open-source design efforts, including CAD releases, manufacturing documentation, and build guides for the broader robotics community
What You'll Bring
3 or more years of hands-on mechanical design experience on high-complexity electromechanical products
Strong proficiency in Solidworks, across both detailed parts, multibody assemblies, surfaces and drawings
Proven track record with sheet metal fabrication and traditional/additive manufacturing
Experience with GD&T and producing 2D engineering drawings for manufacturing and QA
Ability to run FEA simulations; static, dynamic & thermal
