Identify operational issues and recommend improvements to make the e-commerce process more efficient and scalable.

4. Warehouse & Order Fulfilment Coordination

Coordinate closely with the warehouse team on order processing, stock availability, picking, packing and fulfilment.

Follow up on fulfilment issues, stock discrepancies, cancelled orders and returns.

Help establish practical SOPs for e-commerce order and inventory management.

5. New Brands & Online Store Development

Support the setup and launch of official online stores for additional brands and product categories.

Assist with new marketplace account/store setup, product onboarding and launch preparation.

Explore suitable online channels for different product categories.

For products eligible for sale through TikTok Shop, support store setup and operations where applicable.

Requirements

Diploma or Bachelor's Degree in E-Commerce, Marketing, Business Administration, Digital Marketing or a related field.

Preferably 1–3 years of hands‑on experience in Shopee, Lazada or other marketplace operations.

Candidates with practical experience managing an official brand store or marketplace seller account will have an advantage.

Familiar with product listing, marketplace campaigns, vouchers, promotions, order management and basic marketplace analytics.

Comfortable working with Excel/Google Sheets and operational data.

Able to coordinate effectively with warehouse, sales, marketing, IT/system vendors and other stakeholders.
