AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. We're the people who keep the cloud running — supporting all AWS data centers and the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We are looking for a Software Development Engineer II to join our Infrastructure Supply Chain team, building large-scale distributed systems that power one of the world's most complex physical supply chains. Our systems manage hundreds of thousands of rack demands annually across AMER, EMEA, APAC, and GOVT regions — from demand forecasting and material planning to manufacturing execution, logistics, and data center deployment. These are greenfield projects offering a rare opportunity to build systems from the ground up using modern technologies including reactive microservices, serverless computing, and distributed NoSQL data stores.
