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 sponsor ships across Apple Services, including the App Store, Apple News, 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. Because when advertising is done right, it benefits everyone.

The Site Reliability Engineering team within Apple Ads ensures the reliability, performance, and availability of ML Platform and Services  team partners closely with Ads engineering, data science and ML platform teams to enable product delivery through design, configuration, and automation of machine learning infrastructure powering Apple Ads applications.
