China Market & Supplier Research (2 days/week)

• Identify and evaluate potential suppliers for key e‑bike system components (motor, battery, HMI, chargers, sensors, etc.).
• Research China’s electronics ecosystem, emerging technologies, materials, and manufacturing innovations.
• Conduct competitive benchmarking, teardown analysis, and structured documentation.
• Assess supplier capabilities, manufacturing processes, and cost structures.
• Deliver regular reports and insights to support sourcing, technology strategy, and product planning.

Qualifications

• Master’s degree in Mechatronics, Mechanical Engineering, Electrical Engineering, or a related field.
• Strong experience in mechatronic design of rotating systems, drivetrains, or electric motor components.
• Experience in electrical/electronic engineering is a strong plus.
