At Apple, we work every single day to build products that enrich people’s lives. Our Advertising Platforms group makes it possible for people around the world to easily access informative and visionary content on their devices while helping publishers and developers promote and monetize their work. Our technology and services power advertising in Apple News and Search Ads in App Store. Our platforms are highly-performant, deployed at scale, and setting new standards for enabling effective advertising while protecting user privacy.

We are looking for an ambitious individual who can thrive in an Agile environment. You will develop and apply advanced techniques and algorithms to improve an ad network. You’ll be developing and implementing new optimization and advertising algorithms. The position also involves developing a keen understanding of the ad network behavior; detecting meaningful data patterns useful for user engagement modeling; assuring the integrity and breadth of the data; measuring user, campaign and app performance; and finally analyzing the results of extremely large-scale experiments. In addition, the successful candidate will also apply advanced ML techniques for designing privacy mechanisms, encryption techniques, pricing/auction strategies and ranking algorithms, by utilizing data available only on the user’s device.

You will have the opportunity to work on Machine Learning models for an Advertising Platform with extreme scale requirements. You should have experience designing, developing and implementing algorithms combining expertise in machine learning, statistics, optimization, personalization or information retrieval and in analyzing impact on marketplace dynamics, preferably within an ad network. You have an excellent understanding of scalable architectures including operational concerns. Your ability to be a great teammate under tight deadline constraints is key to success.
