Principal Software Engineer

Mixer is the newest addition to the Xbox family. At Mixer we’ve redefined the rules for what constitutes live streaming. We don’t talk about delay in terms of seconds, in our world we operate in milliseconds. With an end to end delay as low as 250 milliseconds, we’re able to do things never thought possible to make the viewer experience far more engaging and interactive. From the obvious; seeing a streamer respond to a chat message instantly, to the exciting; allowing a viewer to interact directly with the game the streamer is playing, we’ve made the viewers part of the action and we’re not stopping there!

Mixer is looking for an engineer to join our video team. We are looking for an individual with experience building ultra-low latency micro services specifically for real time media applications to help build our next generation low latency video stack.

• 8+ years of professional software development experience
