In the Ad Platforms group we help developers drive app discovery across the App Store, help advertisers promote their products along trusted content from publishers in Apple News and Stocks, and help sponsors connect with audiences in live sports on Apple TV. Everything we do is with the unwavering commitment to privacy you expect from Apple. Because we believe when advertising is done right, it benefits everyone.\nDescription\nWe build the on-device systems that deliver ads across the Apple ecosystem: OS daemons, frameworks, and SDKs that fetch, rank and filter ad candidates; enforce ad policy and legal compliance; and protect user privacy before our partner apps even render anything.\nThis is not a UI or app-building role: this is a systems and platform engineering position that requires working knowledge of cross-process communication, concurrency, on-device business logic, and privacy-by-architecture at scale.\nMinimum Qualifications\nDeep, expert-level understanding of OS fundamentals (process/memory management, scheduling, file systems), on any platform - Apple experience not required\nExtensive professional software development experience in a C-like language, including systems with significant scale and reliability requirements\nExpert-level understanding of cross-process communication and concurrent programming - multi-threading, synchronization, locking, and reasoning about races/deadlocks in production systems\nTrack record of designing and operating high-performance client SDKs or libraries at scale - including caching, versioning, breaking changes, and feature-flagged rollouts, with demonstrated judgment on tradeoffs\nDemonstrated experience owning architecture and technical direction for complex, long-lived codebases, including legacy components, and driving multi-team initiatives to resolve structural issues in them\nProven ability to operate with significant ambiguity, set technical direction without a playbook, and drive alignment across engineering, product, and business stakeholders\nHistory of mentoring and growing other senior engineers; excellent written and verbal communication, including with non-technical partners\nBachelors Degree or equivalent experience.\nPreferred Qualifications\nAd tech; Apple-platform fundamentals incl.
