Product Engineer (Mobile)

Cardboard is a video editor you can talk to. It runs in the browser and as a Mac app. Most footage is shot on phones, and there is no mobile app yet. The Product Engineer (Mobile) will build v1 from scratch and decide what Cardboard on a phone should be. The team cares more about taste and craft than any one stack.
