Chief Technology Officer (Mobile app, M/F/D)

Arise is a globally active weight-loss app with over 10 million downloads and a 4.6 rating on the App Store. Our mission is simple but ambitious: empower millions of people to become healthier and happier.

We're looking for a CTO who is a true architect on both iOS and Android — someone deeply skilled in iOS who can take full ownership of our existing app and raise it further, and who can also build our Android app from scratch. You'll develop primarily through AI rather than by hand, and you'll thrive on ownership, precision, and long-term thinking. This role is for someone who ships high-quality code today while foreseeing how today's decisions shape the app for years ahead — technically, strategically, and financially.

Today Arise is iOS-only, so this is where you'll start and where you'll prove yourself: owning, deepening, and future-proofing a mature codebase used by millions. From there, you'll architect and build our Android app from the ground up.
