Liftoff

Liftoff is an ML-first company that helps mobile app companies grow their userbases. We are still a small engineering team but operate at a scale that is rare to find outside of large tech companies (millions of events per second, billion+ samples ML training sets, etc.). Our list of ambitious new ML projects is growing faster than our ability to ship them, so we are hiring ML engineers in both of our engineering offices (Palo Alto and Paris).
