Responsibilities include answering customer emails, handling live chat, managing social media messages and comments on Instagram and Facebook, supporting order fulfillment, tracking orders, processing refunds and cancellations in Shopify, and resolving where-is-my-order questions. You will also provide general administrative support, including order processing, data entry, and basic spreadsheet updates across both brands.
