Join Amazon's Fulfillment by Amazon (FBA) team to build the next generation of mission-critical systems that power the ability to send, store, and manage billions of products globally. FBA provides world-wide sellers access to Amazon's vast distribution network as a service, similar to how AWS provides infrastructure as a service. This role offers the opportunity to work on large-scale distributed systems that serve sellers from Fortune 50 companies to small businesses across 135 countries. As a Software Development Engineer II, you'll be responsible for creating mechanisms to drive optimal seller behavior for FBA inventory management, reducing supply chain costs, and making it easier for sellers to position their inventory closer to customers. The role combines strategic thinking with hands-on development, working in a startup-like environment within Amazon that offers great flexibility in product and technology direction. You'll be building systems that handle high-volume transaction processing while maintaining Amazon's high standards for engineering excellence. This is an excellent opportunity for someone passionate about large-scale distributed systems and e-commerce technology who wants to make a significant impact on global retail infrastructure.
