At Apple, we focus deeply on our customers' experience. Apple Ads brings this same approach to advertising, helping people find exactly what they're looking for and helping advertisers grow their businesses. Our technology powers ads and sponsorships across Apple Services, including the App Store, Apple News, Maps, and MLS Season Pass. Everything we do is designed for trust, connection, and impact: We respect user privacy, integrate advertising thoughtfully into the experience, and deliver value for advertisers of all sizes -- from small app developers to big, global brands. When advertising is done right, it benefits everyone. Apple's advertising platform connects millions of developers and businesses with users across one of the world's most valuable digital ecosystems -- and the intelligence behind every ad decision lives in the algorithms. As the Director of Algorithms within Ads Engineering, you will lead the applied scientists and ML engineers who build and scale that intelligence: state-of-the-art retrieval, ranking, auction, and budget optimization systems that determine relevance, efficiency, and outcomes at massive scale. This is a role for a leader who wants to solve hard algorithmic problems that matter -- where privacy constraints sharpen the work rather than limit it, and where craft and rigor are the standard.
