Powering the online buying experience for global customers
ASCS builds and operates the systems that host the world’s largest e-Commerce products catalog. We power the online buying experience for customers worldwide, allowing them to find, discover, and buy anything they want, anytime. Our mission is to grow the breadth of product selection available to Amazon’s customers globally and continuously improve product data to drive world class customer experience. We do this at scale by developing state of the art systems, science and processes.
Our massively scaled out systems and models process hundreds of millions of updates on billions of products. We are at the cutting edge of the latest advances in AI/ML Science, pioneering the Large Language Model (LLM) and generative AI applications. Scale is a key component of our success. In order to deliver up to date and comprehensive product information for customers, we continuously stretch the limits of distributed systems and big data processing, and while doing this solving some of the hardest technical problems. As Amazon continues to grow and diversify, the challenges only get bigger, requiring us to continuously innovate as there are no “textbook solutions” at our scale.
