Siri’s universal search engine powers search features across a variety of Apple products, including Siri, Spotlight, Safari, Messages, and News. The Search Data Platform team acts as the “source of truth” for our most fundamental data — such as search activity and content — as well as our core metrics across a variety of products. We enable continuous improvement of the search system by building tools for data-driven decision-making and rapid iteration. As a measurement data scientist, you will own product success metrics, run optimized experiments, build innovative models, and craft intuitive dashboards. The work you do will help to craft the future of the Siri Search and Knowledge product. At Siri, you will work with one of the most exciting high performance computing environments, with petabytes of data, and millions of queries per second. You will have an opportunity to find signals in massive datasets to help drive development of the products that delight our customers every single day.
