Staff Android (Exoplayer) Engineer

About the Role

You'll own video playback across our Android footprint - mobile, tablet, Android TV, and Fire TV. This is deep media engineering, not general app development: ExoPlayer/Media3 internals, adaptive bitrate, DRM, and improving the QoE metrics that matter - startup time, rebuffer ratio, and playback failures.

As a Staff engineer, you'll set technical direction for Android playback, mentor senior engineers, and work closely with backend video, CDN, and data teams
