How will you make an impact in this role?

The Payments Platform is responsible for clearing more than 500 million transactions a year globally, with a value of over 1 trillion dollars (Yep! that is not a typo, trillion with a T). This is a mission critical endeavor, with plenty of interesting engineering challenges in a space that is ripe for innovation. Open banking, ISO 20022, real-time/instant payments, and modern cross-border schemes are revolutionizing clearing and settlement. Our Platform is becoming the gateway to existing and emerging global payment rails; and we are using an innovative integration stack to “speak” the many schemes and formats. Beyond the transactional aspect, our differentiating value is contextual. A rich data backbone and deep integration with enterprise data sources allow us to offer powerful omnichannel APIs and extension points used by developers that build customer facing experiences such as P2P payments, loans, bill-pay, commercial cross border payments, AP automation, and many more.

We are beginning our journey of transforming the technical landscape in our teams to use a microservice architecture and are looking to bolster our technical talent by acquiring full-stack developers, using technologies such as Java, Kotlin, Spring, and React.
