Senior Freelance Android Engineer - Kotlin (m/f/d)

Why voize?

Because we’re more than just a job! At voize, we believe the greatest gift to frontline workers is time - time to care, connect, and be present. Today, that time is lost to admin work that pulls nurses away from what matters most: people.
