Job description

What you will be doing

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

Responsibilities

• Process Optimization: Design, implement, and continuously improve manufacturing processes, layouts, and workflows for brushless DC (BLDC) motor assembly.
• Production Tooling & Automation: Specify, procure, and maintain specialized production equipment such as stator winding machines, magnet insertion fixtures, dynamic balancers, and automated soldering stations.
• Quality & Yield Improvement: Analyze production defects, determine root causes of motor failures (e.g., shorts, bearing noise, or unbalance), and implement corrective actions to maximize yield.
• Standard Operating Procedures (SOPs): Create and maintain detailed work instructions, tooling documentation, and quality control checklists for assembly technicians.
• DFM (Design for Manufacturing): Collaborate closely with the R&D/Design team to ensure next‑generation motor designs are optimized for scalable, cost‑effective, and repeatable mass production.
• Vendor & Supply Coordination: 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).

Qualifications

• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Electrical Engineering, or a related technical field.
• 3+ years of experience in a manufacturing environment, ideally 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.
• Excellent problem‑solving abilities, strong communication skills, and a collaborative mindset to work effectively with both line operators and executive leadership.

Nice to Have

• 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.
