The Role

Are you a Senior Fullstack Engineer looking to build 0→1 products at a mission-driven company? Do you enjoy creating consumer-grade experiences and thrive in high-autonomy startup environments?

We’re looking for a motivated Senior Fullstack Engineer to join Propel and help build new Medicare and Medicaid products from the ground up.

AEP schedule note: This role experiences a predictable work spike from September through early December during the Medicare Annual Enrollment Period (AEP).
