A9.com

A9.com, an Amazon company, solves some of the biggest challenges in search and advertising. We focus on helping people find the things they want.

Great search can seem to customers like it is reading their minds. We start the search experience by giving customers suggestions on how to formulate their queries as soon as they start typing. Once we determine which items are good matches to the customer’s query, our ranking algorithms score them to present the most relevant results to the user. We index millions of documents worldwide, and deploy them on highly scalable massive fleets of servers. We reflect millions of price and inventory changes in real time, and we return relevant results in milliseconds.

Our Visual Search team provides deep learning based computer vision solutions that help our customers use visual information to search and discover the world around them. We power the camera search features found in your Amazon mobile app.

A9 advertising drives the publisher products for Amazon’s ad programs. Our Ad Platform handles billions of queries and supports the web’s largest publishers as well as the smallest independent mobile developers. The result is better quality advertising for publishers and more relevant ads for customers.

Our team is an eclectic group of amazingly talented, highly motivated and remarkably smart people. Team members who are just starting their careers collaborate with PhDs and industry veterans who have expertise in a wide range of disciplines. We’re all intent on solving some of the most complex computing problems to be found in industry and academia, and we get to test our solutions in the real world.

Almost half of A9 is based in Palo Alto, California, with additional locations in Seattle, Atlanta, India, Ireland, UK, Germany, Japan, Romania, and China.
