The Prime Video Title Lifecycle Presentation team sits at the intersection of science, experimentation, and customer experience. We leverage data signals and rigorous testing to present the most engaging information about our content to customers at precisely the right moment. Our mission is to ensure every customer interaction with Prime Video content is informed, relevant, and compelling in order to drive discovery and engagement across our vast catalog.

Every day, hundreds of millions of customers browse Prime Video. We already have a different team working on what to recommend, but this team is solving something harder: why should you watch it?

The team optimizes the signals that convince a customer to press play. Think "Trending Now," "100% on Rotten Tomatoes," or "Most Watched This Week", the contextual cues that turn browsing into watching. Last year, by rigorously testing how we present these signals, we drove 116 million incremental streaming hours. Now we're building what comes next.

We're creating an ML-powered platform that dynamically personalizes content signals for each customer, in each moment, across every surface (detail pages, homepages, carousels, and beyond). The core challenge: given a title, a customer, and a context, which signal (or combination of signals) maximizes the probability of engagement? This is not traditional ranking (we're not deciding which titles to show). We sit downstream of discovery, so once a title is surfaced, we determine the most compelling way to present it so the customer converts.
