Senior Software Engineer, Media

Twitch is the world’s biggest live streaming service, with global communities built around gaming, entertainment, music, sports, cooking, and more. It is where thousands of communities come together for whatever, every day.

We’re about community, inside and out. You’ll find coworkers who are eager to team up, collaborate, and smash (or elegantly solve) problems together. We’re on a quest to empower live communities, so if this sounds good to you, see what we’re up to on LinkedIn and X,  and discover the projects we’re solving on our Blog.

Our Video Team is the backbone of Twitch. Twitch processes a massive amount of live video channels and distributes them using the largest dedicated live video CDN in the world, delivering over 25Tbps to more than 5 million concurrent viewers. In addition to serving Twitch traffic, our video platform is offered as Amazon Interactive Video Service, an AWS service that allows the creation of a live video streaming platform with only a few lines of code. Engineers with our Video Team work across a range of areas including ingest, transcoding, and distribution with the lowest latency high-scale HLS distribution system in the world. 

The Media Technology Engineering team is a center of excellence for streaming media processing (transmuxing, transcoding), codec technologies (H.264/AVC, H.265/HEVC, AV1), media formats (HLS, TS, FMP4), network protocols (E-RTMP, SRT, WebRTC), and media quality analysis (VMAF, PSNR). We design, deliver, and maintain core native software libraries that power production services across the organization. As a cross-functional organization, we develop across many internal production services and collaborate closely with many teams to enable efficient and fast delivery of new media features.
