Senior Fullstack Engineer - SQL, Go, API

About Flossy

We founded Flossy because we’re passionate about quality care and improving the healthcare experience. Together, we’ve built health-tech companies that have simplified the healthcare experience and delivered value for practitioners, patients, and payors.

After selling our last business, we each decided it was time to catch up on our to-dos. Separately, we both made appointments with new dentists and had strikingly similar, frustrating experiences. Finding the right dentist was confusing, reaching their offices involved days-long phone tag loops, and diagnosis and treatment required multiple separate visits. These challenges left us both feeling that the dental care delivery experience was overdue for innovation.

We became obsessed with improving dental. With Flossy, we and our longtime dedicated team members have applied our decades of experience in medicine and technology to build an all-in-one, AI-based dental solutions platform. Our goal is to make dental care painless for everyone involved—practitioners, patients, and payors.

As AI technology rapidly transforms the dental industry, we are deeply committed to supporting our partners’ growth. With a customer-first mindset and the most advanced and affordable offerings in the industry, we aim to be the long-term AI partner for the most successful people and businesses in dental care.
