About The Position

We are seeking a Senior Manufacturing Engineer to lead the development and expansion of our internal motor manufacturing operations. This role will lead our motor manufacturing from initial equipment bring-up through serial production. The ideal candidate combines technical expertise with hands-on execution to optimize processes and ensure scalable, high-quality output.

Requirements

Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Electrical Engineering, or a related technical field
3 years minimum of experience in a manufacturing environment, ideally directly involving electric motors, rotating machinery, or high-precision electromechanical assembly
Deep understanding of brushless motor architecture (stators, rotors, magnetic circuits, KV ratings)
Hands-on experience with precision winding techniques and balancing equipment
Proficiency in 3D CAD software (SolidWorks, Fusion 360, or Inventor) for designing jigs, fixtures, and line layouts
Strong knowledge of Lean Manufacturing, Six Sigma principles, Root Cause Analysis (RCA), and FMEA (Failure Modes and Effects Analysis)
Excellent problem-solving abilities, strong communication skills, and a collaborative mindset to work effectively with both line operators and executive leadership

Nice To Haves

Experience managing equipment vendors, particularly Mandarin-speaking suppliers
An established network of industry contacts for automation equipment, tooling, and metal component sourcing
Ability to work independently with a high level of ownership while maintaining clear and effective communication with cross-functional teams

Responsibilities

Design, implement, and continuously improve manufacturing processes, layouts, and workflows for brushless DC (BLDC) motor assembly
Specify, procure, and maintain specialized production equipment (e.g., stator winding machines, magnet insertion fixtures, dynamic balancers, and automated soldering stations)
Analyze production defects, determine root causes of motor failures (such as shorts, bearing noise, or unbalance), and implement corrective actions to maximize yield
Create and maintain detailed work instructions, tooling documentation, and quality control checklists for assembly technicians
Collaborate closely with the R&D/Design team to ensure next-generation motor designs are optimized for scalable, cost-effective, and repeatable mass production
Work with suppliers to ensure the quality and consistency of incoming raw materials (e.g., Japanese NSK/NMB bearings, Neodymium magnets, high-purity copper wiring, and aluminum bells)
