Staff Software Engineer

AirPay • New York, NY

10d • $160,000 - $220,000 • Hybrid

About The Position

AirPay is building software to make the financial experience in healthcare dramatically better for patients and providers. We partner with leading dental groups and insurance carriers to modernize how practices verify coverage, manage billing, and get paid. We are growing quickly, solving real problems for customers at scale, and backed by top-tier investors including IA Ventures, along with founders of Flatiron Health, Clover Health, Shutterstock, and others. This is an opportunity to join a fast-growing company with real traction and help shape the technical foundation of the business.

We are hiring a Staff Software Engineer to help lead the next phase of AirPay’s technical evolution. This is a high-impact, high-autonomy role for an engineer who wants to do more than just build features. You will help define architecture, guide major technical decisions, mentor other engineers, and partner closely with leadership on the hardest and most important problems in the business. You will work across core products, platform, payments, real-time systems, internal tooling, and AI-powered experiences. Some problems are deeply technical. Others are ambiguous and cross-functional. The common thread is leverage where the work you do should make the entire engineering organization and product platform better. You should be excited about building in an environment where the pace is high, the problems are real, and the best answer is not always obvious.
