Lead Software Engineer

Lead Engineer (Fullstack + Infrastructure)

About Us

We are a small, passionate team dedicated to making a difference in the world of health and wellness. In a system where health insurance determines care accessibility, we are building a solution that supports providers in earning their worth without compromising their client’s ability to afford care. Learn more about our mission at https://www.thrizer.com/about-us.

Thrizer operates at the intersection of fintech and healthcare. Our web application serves as a payment processor for our providers and a medical biller for our patients. The goal is to bring speed and transparency to the flow funds between patient, provider, and insurance so that everyone gets paid fast and reliably.

We are now rebuilding and re-architecting the platform to simplify the codebase, improve performance, and prepare for scale. To lead this next phase, we’re hiring a Lead Engineer who will take full technical ownership of our product. You’ll work directly with the founder to modernize the backend, refactor infrastructure, and set the foundation for an engineering team.
