About the role

Senior motor design engineer responsible for end-to-end motor architecture and validation for high-volume home robotics, focusing on quiet, efficient, scalable motors suitable for consumer products.

Responsibilities

  • 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

Qualifications

  • Technical degree in Electrical Engineering, Mechanical Engineering, or Physics with focus on electromagnetics
  • 5+ years of experience designing motors for high-volume consumer products or automotive applications
  • Deep understanding of motor physics including electromagnetics, thermal dynamics, and rotordynamics
  • Proven track record of shipping custom BLDC, PMSM, or reluctance motor designs in products
  • Experience with motor simulation tools such as ANSYS Maxwell, JMAG, or Motor-CAD
  • Expertise in motor control theory including FOC, sensorless control, and active vibration damping
  • Understanding of acoustic principles related to motor design including slot/pole combinations and skewing techniques
  • Experience with bearing systems, lubrication, and tribology for long-life applications
  • Familiarity with motor manufacturing processes including winding, magnetization, and balancing
  • Knowledge of safety standards and certifications (UL, CE) for motor-driven appliances
  • Comfort with fast-paced, startup atmosphere -- you don't shy away from the hard work
  • High level of maturity, ownership, and pride in your work
