About the role
- We are looking for a Senior Mechanical Engineer to design, test, and implement key hardware components for our humanoid robot platform.
- This is a hands-on role that spans the full development arc - from first prototype on the bench to production-ready design at a contract manufacturer.
- You will own mechanical subsystems end-to-end - from requirements definition through 3D CAD, prototype build, supplier qualification, first-article inspection, and production release.
Responsibilities
- Design parts and assemblies in 3D CAD that satisfy load conditions, form factor constraints, range-of-motion requirements, and durability targets
- Apply analytical methods - FEA, tolerance stack-up, kinematic analysis - before releasing designs for prototyping or production
- Build prototypes to test assembly, range of motion, wire routing, and integration with adjacent subsystems
- Design and build test stands and fixtures
- conduct structured validation testing and document results rigorously
- Own the prototype-to-production transition for your subsystems: apply DFM/DFA principles from the first design iteration, not as a final step
- inspect first articles, perform root cause analysis on failures, and drive corrective action through to closure
- define and own the mechanical acceptance criteria, support tooling bring-up, and stay engaged through production ramp
- Define and execute structured validation plans - including environmental, fatigue, and functional testing - to prove out designs before they lock for production
Requirements
- 5+ years of mechanical engineering experience in robotics, industrial automation, automotive, aerospace, or consumer electronics - with at least one product shipped to production
- Expert proficiency in 3D CAD (SolidWorks, NX, CATIA, Onshape, or equivalent) for complex parts and assemblies with tight tolerances
- Experience with actuators and transmission systems: strain-wave (harmonic), planetary, cycloidal gearing, or direct-drive
- Proven electromechanical integration experience: motors, sensors, encoders, wire harnesses, and connectors in tight mechanical envelopes
- drive design changes required to achieve manufacturability, yield, and cost targets
Nice to have
- Direct experience working with contract manufacturers: DFM reviews, tooling bring-up, first-article inspection, and yield improvement
- Experience with thermal design and heat dissipation in compact electromechanical systems
- Background in reliability engineering: fatigue analysis, HALT/HASS, or accelerated life testing
- Proficiency with simulation tools beyond FEA: CFD, multi-body dynamics (Adams, Simscape), or kinematic simulation
Skills
- Familiarity with functional safety requirements for mechanisms operating near humans
