E-commerce Account Manager (Marketplaces)

About the Role

Numan is on a mission to transform health. To do that, we need to meet our customers where they are. We’ve built a powerful direct-to-consumer brand, and now we are ready to massively scale our footprint across online marketplaces—specifically dominating Amazon (UK & Europe) and TikTok Shop.

Driving European Expansion: Act as the project lead for our upcoming launch into Europe (e.g., Germany, France), navigating international compliance, localization, and supply chain logistics.
