The Prime Video Persona team is at the intersection of high volume distributed systems and machine learning. The team represents the critical piece of the customer understanding pillar of Prime Video upon which all storefront personalization is based. The team focuses on deriving and vending human understandable customer attributes based on ML models and heuristic algorithms (genre affinities, language preferences, etc.). We partner closely with our Applied Scientists on ML research, model evaluation and implementation. We also vend these attributes to a spectrum of personalization teams both inside and outside of Prime Video via our online systems at 50k+ TPS. This is an opportunity to venture into the ML space and/or go deep into ML research (depending on your experience level and interests), while also owning a tier 1 scale system that literally impacts the experience of over 100MM people every month.

Prime Video offers customers a vast collection of movies, series, and sports—all available to watch on hundreds of compatible devices. U.S. Prime members can also subscribe to 100+ channels including Max, discovery+, Paramount+ with SHOWTIME, BET+, MGM+, ViX+, PBS KIDS, NBA League Pass, MLB.TV, and STARZ with no extra apps to download, and no cable required.
