Senior Fullstack Engineer / Tech Lead - Developer Experience Team

Extensions revolutionizes the ways viewers engage with live video, enabling direct interaction between viewers, games, and external services. With Extensions, the Twitch community can interact in ways that were never thought possible - from heat maps and real-time game data overlays to mini-games, music requests, and leaderboards. We are supporting our developers to create a diverse offering of apps which will unlock new ways to experience gaming and digital entertainment.

We are seeking a strong technical leader in San Francisco or Seattle to help guide us as we set out to create an awesome array of new Extensions features. This is an individual contributor role and candidates should have strong back end experience and at least some experience with front end. You’ll have the opportunity to guide architecture decisions, contribute code directly, weigh in on product design, mentor other engineers, and build software for the world’s leading video platform and community for gamers, with over 100 million visitors per month. Not only that, you’ll get to work on an exciting road map, and to help build the products and tools that enable both developers and broadcasters to achieve their goals.
