In wholesale banking payments processing, we are looking for an experienced backend software development engineer. We would like to hear from you if your dream is to develop real-time payment systems and you believe that you can live by the agile manifesto practicing agile scrum.

What happened in the past

In 2014, ING suffered from various outages in payments processing and it was repeatedly reported by newspapers and television. ING management started a taskforce 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 which could perform real-time process payments which was far better than all kind of 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 SEPA Credit Transfer payments for all European ING entities. This includes new connectivity to many Account Management Systems and Clearing Houses. Think of real-time and batch high volume asynchronous processing, stateless communication, resilience patterns, idempotent application design and much more.

What you’ll do

You will focus predominantly on the extension of the existing payment routing engine to support multiple European ING entities. This clustered application is written using java 11 and reactive streams approach. 

You will work in the dynamic and challenging environment of the IT organization of ING WB Tech 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 demos recorded as videos and published on internal streams channels to the business, so that at the end there are no surprises about what we build.

What we are looking for

We expect you to speak English and to have 6 (or more) of the following skills

• Demonstrable experience producing reusable code components

• 3+ years of software engineering experience on Java, Spring Boot, Restful API and supporting libraries

• Understanding the clustering technologies and issues, such as Cassandra clusters

• Understanding of the way the distributed systems work (i.e., you have the ability to explain the CAP theorem and Two Generals problem)

• Experience with containers (Docker, docker-compose, Kubernetes)

• Understanding of the Messaging platforms (i.e., Kafka, ActiveMQ, IBM MQ

• You think of security and failure during design

• Secure by design

• Experience with XML processing and validation

• Understanding the NoSQL data modeling (i.e., Cassandra)

• Understanding the SQL data modeling (i.e., Oracle)

• You have a learning attitude. Not only to master new technologies and programming languages, but also on the personal level. You are able to give and receive feedback

You will have an added advantage if you have any of the following

• A Master’s Degree in Computer Science/Mathematics or relevant knowledge

• Experience in the financial industry, preferably payments

• Passion for the reactive programming

• Experience in creating CI/CD pipelines (i.e., Azure DevOps, GitHub)

• Open-Source contributions / active GitHub profile

• Familiarity with functional programming

• Experience on Scala or Kotlin

• Knowledge of ING polymer and lit will be nice to have because there are few screens that are updated once per year
