E-commerce Operations Management | Multi-channel integration

We are a growing T-shirt brand looking for an experienced E-commerce Solutions Specialist to streamline our operations. Currently, we sell across multiple platforms, including Amazon and Walmart, and we need a robust, automated system to manage our listings, inventory, and order fulfillment from a single source of truth. The ideal candidate will help us implement (or optimize) a multi-channel management solution to ensure we never oversell and that our product data remains consistent across all storefronts. Key Responsibilities: Centralized Integration: Set up or refine a multi-channel management tool (e.g., Cin7 Core, Rithum/ChannelAdvisor, Sellbrite, or ChannelEngine) to sync Amazon Seller Central and Walmart Seller Center. Inventory Synchronization: Implement real-time inventory tracking to manage high-volume T-shirt variants (size/color matrices) and prevent stockouts or overselling. Bulk Listing Management: Automate the process of pushing new designs and product listings to both Amazon and Walmart using flat files or API-driven tools. Order Fulfillment Automation: Ensure seamless routing of orders to our fulfillment centers (FBA, WFS, or 3PL). Performance Optimization: Monitor listing health, resolve sync errors, and ensure all product data meets the specific SEO requirements of each marketplace. Required Skills & Experience: Software Proficiency: Experience with enterprise-level tools such as Cin7, Channable, Rithum, or Shopify Plus for multi-channel orchestration. Data Accuracy: Strong attention to detail regarding SKU architecture and variant mapping. Problem Solving: Ability to troubleshoot API connection issues and marketplace-specific listing errors. Preferred Qualifications: Experience with TikTok Shop or eBay integration. Knowledge of AI-driven listing optimization tools (e.g., Nifty or Mergado). Familiarity with Print-on-Demand (POD) or 3PL workflows. How to Apply: Please provide a brief summary of a similar multi-channel integration project you have completed. Include the specific software you used and how you handled inventory synchronization for a business with high-variant catalogs.
