Principal Finance Manager, NA Supply Chain Finance

Amazon"s fulfillment network is one of the most complex supply chain systems in the world, and how we place inventory across it directly determines whether customers get faster delivery at lower cost. We are seeking a Principal Finance Manager to lead the financial strategy that shapes how billions of dollars of inventory flows into our US sortable fulfillment network.

In this role, you will provide the insights and frameworks that help senior leaders make placement decisions balancing customer experience (faster delivery, higher in-stock rates) with Amazon"s cost to serve. You will operate at the intersection of inbound transportation, fulfillment center operations, and outbound shipment, translating complex supply chain trade-offs into clear financial narratives that drive action. The breadth is unique: from billion-dollar network transformations to daily execution optimization, you will be the financial voice that connects it all.
