About The Position

As a Motor Design Expert, you'll architect the actuators of our robotic systems - the motors that power every movement and action. You'll work at the intersection of electromagnetics, acoustics, and controls to create motors that are whisper-quiet, incredibly efficient, and manufacturable at scale. If you're passionate about pushing the boundaries of motor technology and obsessed with achieving the impossible combination of performance, silence, and cost, we'd love to talk to you about how you can help us revolutionize home robotics.

Requirements

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

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
