Position Summary

G10 Inc is seeking an experienced Vendor Manager to fully own the relationships, negotiations, and operational needs of our Mandarin-speaking vendor partners, and to support the Sr. Vendor Manager on additional vendor accounts as needed. Working closely with the Sr. Vendor Manager, this role serves as a critical bridge between G10's US-based operations and Chinese vendors who sell their products online through G10 on Amazon and other U.S. marketplaces. The ideal candidate has hands-on experience supporting Amazon e-commerce operations, a strong understanding of distribution and fulfillment logistics, and the ability to negotiate commercial terms confidently across cultures. This role operates on a second-shift schedule aligned with China business hours to support real-time vendor communication.

Key Responsibilities

• Own end-to-end relationships with Mandarin-speaking vendor partners, serving as their primary point of contact and conducting business communication in both Mandarin and English.
• Own the day-to-day operational needs of assigned vendors across Amazon Vendor Central (1P) and/or Seller Central (3P), including catalog management, item setup, purchase order management, and operational troubleshooting.
• Own negotiation of vendor agreements, commercial terms, pricing, and distribution arrangements for the Mandarin-speaking vendor portfolio.
• Set vendor management strategy and negotiation targets, establishing priorities and performance goals for the vendor book of business.
• Lead vendor business reviews and drive resolution of complex or escalated vendor issues.
• Coordinate with internal teams on inbound inventory planning, fulfillment center operations, and supply chain logistics.
• Monitor vendor performance and compliance, escalating issues as needed.
• Maintain accurate records of vendor communications, contracts, and operational updates.
• Support the Sr. Vendor Manager on vendor accounts that need Mandarin-language support or additional capacity, including communication, negotiations, and operational follow-through.
• Support cross-functional projects related to new vendor onboarding and program expansion.
• Work the second-shift schedule (Monday-Thursday 2:00 PM - 10:00 PM Pacific / 4:00 PM - 12:00 AM Central; Fridays starting 9:00 or 10:00 AM Pacific / 11:00 AM or 12:00 PM Central) to ensure real-time availability for vendor partners in China. Specific hours and days are flexible and can be negotiated, provided that roughly 25-30 hours per week overlap with China business hours; schedules may be adjusted as vendor needs change.
• Any other duties as assigned.

Requirements

Skills

• Strong negotiation skills with a track record of managing commercial vendor relationships independently.
• Demonstrated ownership of $100M+ portfolio in annual revenue.
• Demonstrated experience supporting Amazon e-commerce operations (Vendor Central or Seller Central).
• Experience with distribution, logistics, or fulfillment operations.
• Ability to work a primarily second-shift schedule overlapping China business hours from a US-based location (Pacific or Central time zones preferred).
• Highly organized with strong attention to detail and the ability to manage multiple priorities and guide junior team members.
• US-based with existing cross-cultural business experience.
• Familiarity with Amazon 1P vendor operations and purchase order management.
• Hazmat certification (e.g., DOT 49 CFR, IATA DGR, or IMDG), or experience managing hazardous materials products and compliance for e-commerce.

Education and Experience

• Professional-level English and Mandarin writing and speaking proficiency (required)
• Bachelor’s degree in supply chain, finance, business, international business, or related field or equivalent experience (required)
