Software Engineer - Distributed Systems

Apple Ads helps developers and businesses reach customers on the App Store through highly relevant, privacy-focused advertising. Our engineering teams build the infrastructure that powers ad delivery at Apple scale — from search and retrieval to auction, ranking, and measurement. We are looking for a Software Engineer to join the team responsible for Apple Ads' Ad Delivery Services — the runtime and offline systems that decide, for every ad request, which candidates are eligible, safe, and available to serve.

Ad Delivery Services sit on the critical path of every impression Apple Ads serves. The team owns capability areas across Budget & Spend, Ad Delivery Policy, Traffic Quality, Request & Query Understanding, and Targeting Enrichment. Each capability is a low-latency service called inline during ad serving, plus the offline pipelines that keep it accurate.

You will design and operate services that handle high request volumes with tight latency budgets, evolve them to support new ad placements and product surfaces, and partner closely with adserver, auction, ML, and data platform teams across Apple Ads.
