Software Engineer | Product Data

Yapily is on a mission to enable innovative companies to create better and fairer financial services for everyone, through the power of open banking. Yapily is an open banking infrastructure platform solving a fundamental problem in financial services today: access. Historically, card networks have monopolised the global movement of money, and banks have monopolised the ownership of, and access to, financial data. Yapily was founded to challenge these structures and create a global open economy that works for everyone. We exist behind the scenes, securely connecting companies - from growth to enterprise - to thousands of banks worldwide, enabling them to access data and initiate payments through the power of open banking.
