Are you passionate about solving complex fulfillment challenges at global scale? Join Seller Flex and help transform how third-party sellers fulfill Amazon orders worldwide.

This role offers a unique opportunity to become a domain expert in 3P fulfillment while rearchitecting core systems for global expansion and scale. You'll work at the intersection of marketplace platforms, warehouse operations, and inventory systems — simplifying architecture, solving high-impact seller problems, and establishing the technical foundation for launching new countries like Japan.
