Amazon brings buyers and sellers together. Our retail customers depend on us to give them access to every product at the best possible price. Our sellers depend on us to give them a platform to launch their business into every home and marketplace. Making this happen is the mission of every engineer on the Amazon North American Stores Expansion (NASX) team. We are looking for exceptional SDEs to help build vendor negotiation tools that will help scale Amazon's Always On Negotiation system to ensure that we incorporate changing market variables into our purchasing decisions to give our customers the best prices available for everything we sell.
