The Mission

In 2014, ING suffered from various outages in payments processing and it was repeatedly reported by newspapers and on television. ING management started a task force to mitigate the issues. However, the real solution was born at an ING Hackathon a few months before. In just 24 hours the winning team delivered a prototype that could process payments in real-time which was far better than the batch processing used so far. The new system was named Real-Time Payments Engine which nowadays processes hundreds of millions of Loan, Savings and Payments transactions per year.

At this moment we are building the platform for Instant Payments and Single Euro Payments Area (SEPA) Credit Transfer payments for all European ING entities. This includes new connectivity to many account management systems and clearinghouses. Think of real-time and batch processing of high volume asynchronous, stateless communication, resilience patterns, idempotent application design and much more.

Your day to day

• You will focus predominantly on the extension of the payment routing engine to support multiple European ING entities; this clustered application is written using Java 11 and the reactive streams approach;
• You will work in the dynamic and challenging environment of wholesale banking technology (WB Tech) in Tribe Payments;
• We operate according to a Scrum development process with two-week sprints and strongly believe in the DevOps approach to delivering IT solutions;
• We strive to have the high-quality mission-critical software delivered in time using iterative development with regular milestone reviews with stakeholders following the ING's agile way of working to reduce surprises in what we build.
