ML Research Engineer, Search - Apple Services Engineering
The Apple Services Engineering (ASE) team is one of the most exciting examples of Apple's long-held passion for combining art and technology. These are the people who power Search for the App Store, Apple TV, Apple Music, Apple Podcasts, and Apple Books. And they do it on a massive scale, meeting Apple's high expectations with high performance to deliver a huge variety of entertainment in over 35 languages to more than 150 countries. These engineers build secure, end-to-end solutions. They develop the custom software used to process all the creative work, the tools that providers use to deliver that media, all the server-side systems, and the APIs for many Apple services.
Thanks to Apple's unique integration of hardware, software, and services, engineers here partner to get behind a single unified vision. That vision always includes a deep commitment to strengthening Apple's privacy policy, one of Apple's core values. Although services are a bigger part of Apple's business than ever before, these teams remain small, nimble, and cross-functional, offering greater exposure to the array of opportunities here.
Description
The ASE Search Research team sits at the intersection of cutting-edge research and production-scale impact. We follow state-of-the-art developments in machine learning, information retrieval, and natural language processing-then bring those innovations into Apple Services Search products used by hundreds of millions of people daily. We're looking for engineers with strong research instincts who can identify promising techniques in the literature, adapt them to our unique challenges, and ship them at scale.
