Matic is a company focused on revolutionizing home robotics with innovative products like their Wall-E-esque floor cleaning robot. They are seeking a Motor Design Expert to lead the design and architecture of motors for their robotic systems, emphasizing performance, efficiency, and manufacturability.
Qualification
- Expertise in motor design and architecture
- Strong background in electromagnetics, acoustics, and controls
- Experience with electromagnetic FEA simulations
- Knowledge of motor control algorithms and drive electronics
- Ability to develop and validate motor specifications
- Experience in designing testing protocols for motor failure modes
- Strong collaboration skills to work with suppliers and cross-functional teams
- Passion for innovation in motor technology and home robotics
Responsibility
- Own end-to-end motor architecture from electromagnetic design through production validation for all motorized subsystems
- Design custom motor solutions optimizing for acoustic performance (<60dBA), efficiency (>85%), form factor, cost (<$15/unit), and scalability to 100k+ units/year
- Perform electromagnetic FEA simulations for motor optimization including flux density, cogging torque, and back-EMF analysis
- Select and validate motor control algorithms, drive electronics, and feedback systems for precise motion control
- Develop motor specification requirements balancing torque density, thermal management, and acoustic emissions
- Design accelerated life testing protocols specific to motor failure modes including bearing wear, insulation breakdown, and demagnetization
- Collaborate with suppliers on custom rotor/stator designs, winding patterns, and manufacturing processes
- Drive cost reduction initiatives through design optimization, material selection, and manufacturing process improvements
- Work cross-functionally with NVH, controls, and thermal teams to achieve system-level optimization
