The single threaded owner (STO) of an amazing global team who have designed and built a secure, multi-region, Tier-1 data exchange for Amazonian people data, powered by AWS, to support builders across Amazon that have created thousands of innovative systems that Amazonians rely on every day. We support over 3.5m employees and contingent workers, and share over 1 trillion employee records every year through billions of API calls to our services. We obsess over helping builders move fast and well, ensuring our services are as reliable as electricity and water, and how we continuously improve by operating transparently.Our mission is to be the "everything store" for teams across Amazon to easily: see what people and workplace data is available, navigate privacy and security reviews with ease and minimal effort, and access the data they are approved to consume – all while earning candidates’, employees’, and alumni trust by maintaining a high privacy and security bar.Amazon is constantly challenging existing assumptions about the way things work and reinventing as we approach new challenges and opportunities. We’re taking that entrepreneurial, revolutionary spirit and applying it to how we imagine and deliver innovative experiences to support our growing employee base. Amazon’s peculiar culture is one of the primary reasons we’ve been so successful in so many diverse areas.
