Software Engineer (Video) - Periscope

San Francisco, CA


Who We Are:

Just over a year ago, we became fascinated by the idea of discovering the world through someone else’s eyes. What if you could see through the eyes of a protester in Ukraine? Or watch the sunrise from a hot air balloon in Cappadocia? It may sound crazy, but we wanted to build the closest thing to teleportation. While there are many ways to discover events and places, we realized there is no better way to experience a place right now than through live video. A picture may be worth a thousand words, but live video can take you someplace and show you around. Periscope was started by a few friends and the idea of letting people see the world through someone else’s eyes, a visual pulse of what’s happening - right now. Over the last few months, we have expanded the team and are looking for people just as excited about this vision.  

What You'll Do:

Our immediate need is for someone to design and implement real-time video stabilization for mobile clients. Going forward, the position would own video processing pipelines both on mobile clients and backend servers that optimize the viewing experience provided by a system where video is captured by amateur videographers with handheld devices, streamed up to a server over a link of varying quality, and streamed down to an audience of a few or a few thousand viewers, each with varying device capabilities, display resolutions. and link qualities -- all while latency is constrained to allow interactivity between the broadcaster and viewers. 
 Assist in the development of computer vision-based features

Who You Are: 
  • You consider yourself a a great teamate. 
  • Solid background not just in image and video processing, but also as a software developer. 
  • Experience in computer vision and graphics or experience developing on mobile platforms would be a huge plus. 
  • Prior experience developing gyro-based video stabilization with rolling shutter correction is also desired.
  • BS in Electrical Engineering or Computer Science. MS. or Ph.D. preferred.
