Join Twitch's Mobile Core Engineering team as an Android Software Engineer and help shape the foundation of mobile development across Twitch. As a platform team, Mobile Core provides critical tools, frameworks, and best practices that empower all mobile engineers at Twitch to build exceptional experiences for millions of users. Twitch is evolving its mobile strategy from native-first to a hybrid approach that leverages React in WebViews alongside native Android capabilities. You'll work on high-impact initiatives including our hybrid web-to-mobile platform, performance optimization at scale, automated testing infrastructure, and developer tooling that accelerates velocity across the organization. Your work will directly impact how hundreds of engineers build features and how millions of users experience Twitch on Android. This role requires independent operation and technical leadership, as you'll regularly provide guidance to product teams across Community and Commerce organizations. This position can sit in San Francisco, Irvine, or Seattle.
