FlipaClip - Staff Backend Engineer
About FlipaClip
FlipaClip is the world’s biggest animation app with over +90 million lifetime installs.
FlipaClip turns any mobile device into an animation studio.
Animated movies and shows require massive budgets, years of production, or the approval of a handful of studios to exist. That’s how the industry has worked for decades.
Very soon, a blockbuster animated movie will be entirely produced by a 15-year old in her parent’s basement. On a phone. And it will be made and distributed for $0.
We are on it.
