Marketplace Specialist

A Marketplace Specialist manages, optimizes, and scales a brand's product catalog, visibility, and sales performance across third-party e-commerce marketplaces (e.g., Amazon, Walmart, eBay, TikTok Shop, Etsy, Jumia). Operating at the intersection of algorithmic search engine optimization (SEO), paid search advertising, inventory logistics, and inventory forecasting, they bridge the gap between digital consumer traffic and transactional conversion on massive retail platforms. They manage the complete marketplace operational lifecycle—from creating SEO-optimized product listings and managing A+ content to executing PPC advertising campaigns, monitoring account health metrics, and resolving supply chain disruptions or policy violations. This role exists across direct-to-consumer (DTC) brands expanding into multi-channel retail, brand aggregators, third-party seller agencies, and enterprise manufacturing corporations. Marketplace Specialists collaborate closely with supply chain managers, graphic designers, digital ad buyers, customer support leads, and platform account managers. Standard schedules balance daily advertising bid adjustments, performance dashboard analytics, and catalog auditing with listing troubleshooting, inventory replenishment tracking, and strategic promotional planning. Analytical agility, meticulous platform compliance, and obsessive data tracking define the core of the profession.
