Who We Are
We obsess over great playback experiences. We want playback to start immediately, at great quality, and we never want playback to stop unexpectedly. 

To provide the best possible streaming experience, we design algorithms that adapt audio and video qualities to ever-changing network conditions, encoding profiles, UI features, and device capabilities. Our team comes from diverse backgrounds, has an equal gender ratio, and has a wide range of expertise in computer networking, video streaming, data analysis, embedded systems, and software engineering. 

Beyond the subscription-based video-on-demand service, we help Netflix expand into Live Streaming and Advertisements. We work highly cross-functionally and jointly develop our algorithms with Netflix CDN, Encoding Technologies, Data Science & Engineering, Consumer Insights, and UI Engineering.
