Fullstack Software Engineer (x/f/m) - Core Billing Platform

About the role

Health can’t wait . Not for symptoms to get worse. Not for a six‑month appointment. Not for a system to catch up. But that’s exactly how healthcare works today. You wait, until you can’t. Alan exists to end the wait. Health is a universal right, and we believe this right can only become real when it’s coupled with prevention.
