Amazon Fulfillment Technologies (AFT) powers the physical engine at the heart of Amazon. AFT forms the invisible back half of Amazon that magically turns your click of a button into packages at your door. We build and operate the software, hardware, and processes that run the global network of Fulfillment centers(ie, Amazon warehouses), which move billions of units of inventory and ensures customers get what they want when promised.

You will have an opportunity to own design and development of distributed systems and contribute to a wide range of projects in a highly collaborative and fast-paced environment.
You will be involved in all the aspects of the software development cycle including scoping, design, implementation, testing & delivery of your product. A commitment to teamwork, hustle, and strong communication skills are absolute requirements. Creating reliable, scalable, and high-performance services and architectures require exceptional technical expertise. If you have that type of expertise, you are customer centric and motivated about building systems that can be operated at global scale with minimal human intervention, then we want to talk to you!

- We collaborate as a team to design and build solutions using a variety of languages and technologies on a daily basis. We attempt to find the best technology to solve the problem at hand and in many cases that means exploring new technologies that we haven’t used before.
