Twitch is building the future of interactive entertainment. Recommendations (matching viewers with live content they greatly enjoy), is core to that vision. As an applied scientist on Twitch Recommendations Team, you will help design, prototype and implement algorithms and techniques connect Twitch users with the right content. This is a broad problem, and may include extracting and using data from live video using computer vision (CV), or from chat using natural language processing (NLP). By improving Twitch’s recommendation products using machine learning, you will help Twitch’s viewers have a great experience, and help Twitch’s broadcasters find more passionate fans.

At Twitch, a part of Amazon, you’ll experience the benefits of working in a dynamic, entrepreneurial environment in the heart of San Francisco, while leveraging the resources of Amazon.
