Senior Software Engineer

About Us Nopan is a payment performance platform built by former merchants, focused exclusively on account and wallet payment methods. We help large merchants, fintechs, and PSPs turn payments into measurable revenue drivers. We are payments nerds who are excited about global changes happening in the industry and we want and know how to make it better. In just 18 months, we secured our license from the Dutch Central Bank, formed partnerships with Europe's major payment schemes, including becoming a Principal Member of EPI/Wero, and went live with initial customers. Backed by leading investors, we are now scaling to become the default performance layer for account and wallet payments in Europe.
