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.
