Experience building and scaling a search optimization and experimentation program-not just tuning individual ranking models or running isolated A/B tests, but establishing the experimentation framework, relevance metrics, statistical rigor, and decision-making processes that enable continuous improvement of search quality, ranking, and discovery. This Senior Product Manager role sits within the Marketplace Experience team, the product group that owns the buyer-facing surfaces of AgentExchange: search, discovery, homepage personalization, and the experimentation program that continuously improves them.
