You"ll partner closely with product managers, applied scientists, and economists to shape the long-term vision for attribution measurement - determining how Amazon Ads should measure increasingly complex customer journeys, translating new methodologies into scalable production systems, and making deliberate tradeoffs across measurement accuracy, signal coverage, latency, privacy, transparency, and infrastructure cost. Building accurate attribution at Amazon scale is a uniquely challenging engineering and scientific problem: our systems must connect signals across complex customer journeys, advertising products, devices, and channels while navigating fragmented identity signals, evolving privacy requirements, changing measurement methodologies, and increasingly sophisticated advertiser needs.
