The Core Services team owns the charter of evaluating bad actor risk of all kinds (Buyer, Seller, Brand, Vendor) across entities such as Orders, Returns, Sign-ins, Listings and any event that will be useful to evaluate risky behavior. We build self-service capabilities to experiment and launch new use cases while making it easy to on-board and manage existing ones all over the world. We are the gate keepers of customer trust by preventing bad actors from doing damage to good customers or scamming Amazon. The problems we solve will challenge the best in terms of scale (100s of billion evaluations) and latency (think milliseconds) while operating at the lowest cost
