This squad is responsible for the foundational data, services, and tooling that power the ad-serving ecosystem, with a focus on three core areas: Data Architecture and Integrity, Targeting Data Propagation, and Observability and Debugging. They design and own the data architecture to ensure the accuracy and timeliness of core ad-serving datasets for pacing, billing, and business analysis. They also manage the services and pipelines that reliably deliver critical user-targeting information—such as privacy preferences, ad history, and audience segment data—to the ad-serving path. Furthermore, the team develops tools and mechanisms to enhance telemetry within the ad-serving stack, enabling more effective debugging and easier evaluation of system changes, while also providing necessary support for new feature development by handling their specific data and event functionality requirements.
