Principal Software Engineer - Priority Commerce

Who Is Priority & How Are They Changing the World

Priority Commerce is a large-scale payments and commerce platform that processes billions of dollars in transactions for a vast network of merchants. Historically focused on the U.S. market, Priority is now undertaking a major international expansion - re-architecting core systems to support multi-currency, multi-market, and regulatory-compliant payments across Canada, Europe, Mexico, and beyond. This work touches every layer of the company, from merchant onboarding and payments to reporting and billing, and will unlock growth opportunities potentially larger than Priority’s existing U.S. business.

As a Principal Software Engineer on the International Product team, you will play a foundational role in taking Priority global. You will help architect and deliver highly reliable, secure, and scalable systems that support international payments across 135 currencies and multiple regulatory environments. This is a greenfield opportunity with real customers already lined up, where your architectural decisions will directly impact customer experience, system reliability, and Priority’s ability to operate worldwide.
