Software Engineer - Algo, Ad Platforms

Santa Clara Valley (Cupertino), California, United States
Software and Services


Role Number:200501763
At Apple, we believe in the power of technology to enrich people's lives. Everything we build is designed to empower people, including our advertising platform. We deliver ads in a way that benefits both customers and advertisers — helping people discover content, supporting creators, and protecting and respecting everyone’s privacy. Our technology makes advertising possible on the App Store, Apple News, Stocks, and Apple TV. 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! Everything we do is with the unwavering commitment to privacy you expect from Apple. Because when advertising is done right, it benefits everyone! We are looking for an ambitious and versatile engineer who can thrive in an Agile environment, delivering solutions to enable advanced techniques and algorithms to improve an ad network. You will work closely with ML Scientists to develop and implement platform components that will allow advertising algorithms to optimize and scale. Platform components can range from core data processing capabilities and mission-critical pipelines, to online serving architectures that react to real-time signals while preserving the privacy and integrity of our consumers. You will have the opportunity to define, refine, and/or refactor approaches, designs, and architectures to meet the ad network challenges we must solve. You will join a team of world-class machine learning engineers hungry to apply leading-edge technologies to deliver extraordinary experiences to our customers. You will play a meaningful role building machine learning products which deliver on Apple's privacy commitments and change the way advertising works with data. The position also involves developing a keen understanding of the ad network behavior; the common engineering solutions to enable leading edge ad network algorithms; supporting in-depth and in-width A/B tests; developing tools for analyzing the results of extremely large-scale experiments.

Key Qualifications
