Amazon’s global fulfillment network enables any merchant to ship items to almost any place on earth. Items move between vendor locations, Amazon warehouses, and customers through a complex transportation network. Amazon warehouses, and customer locations before reaching the customer. At a scale of millions of packages, each with different attributes and delivery requirements, this results in a complex transportation optimization problem. Our organization supports planning for a broad range of Amazon businesses including Amazon Logistics, Amazon XL, Ship With Amazon, and more.
As a Senior Software Development Engineer on the Routing Platform team you will take ownership of the technical design, implementation, production delivery and support of scalable software services built natively in AWS responsible for generating the route that a transporter takes on the Last Mile of the packages journey - from the Amazon Delivery Station to the customer's address. If you aren't already, you will become an expert in multiple AWS offerings, including Step Functions, Lambdas, Fargate, DynamoDB, S3, Cloudwatch, SNS/SQS, and others. Your work will directly impact Amazon's bottom line, with projects the team drives responsible for hundreds of millions of dollars in yearly entitlements.

About the team
The Routing Platform team has four pillars: 1) building reusable components and maintaining workflows responsible for input collection for different businesses as well as the external APIs for Route Planning, 2) hosting the optimization algorithms to solve the Vehicle Routing Problem, 3) managing route lifecycle inclusive of providing a source of truth for route status and tracking route state changes, 4) managing core routing frameworks and providing simulation capabilities for all systems. Sr. Engineers are involved in code and often lead initiatives across two or more of the Routing Platform teams as well as across organizations. Due to the criticality of the owned systems, we collaborate closely with three Principal Engineers within the broader organization. This position will focus primarily on hosting the optimization algorithms, and work closely with others teams to deliver solutions
