Backend Test Engineer

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 build a simple engine which could process payments in real-time. This really improved customer experience compared to the batch processing used so far. On top of that it was built on Cassandra, a distributed database technology. In the months and years that followed, the Hackathon concept was expanded towards a full-blown Cassandra clusters running over three data centres with the necessary application software on top of it. We now have an application that is running the real-time and batch processes in parallel and it’s designed to tolerate failure! This new system is now fully up and running and processes around 5 million real time and batch payments a day.

Now we are facing a large scope extension. The main load is currently from the Dutch customers, but we will extend our scope for to Europe and worldwide! This includes new connectivity to many account management systems and clearing houses. Technically this is about Java, Kafka, Akka, Cassandra and Tibco. Functionally, this is about real-time, batch, high volume asynchronous processing, stateless communication, resilience patterns, idempotent application design and much more. The top engineers who won the Hackathon and delivered the payment engine are also driving the next level. We are looking for abackend test engineer to strengthen our the area!

What you’ll do

Your squad is responsible for the maintenance and operations of a part of the payment engine. Each engineer has his or her specialty and your specialty is testing. You will make sure the application is of high quality on all aspects (functional, performance, resilience, security). Most of our tests will be automatically executed and therefore test automation will be part of your job. As the whole team is responsible for maintenance and operations, we expect you to take part of standby as well.

Next to the squad you will also be part of a chapter. The chapter consists of test engineers from different squads. Within the chapter you focus on quality and continuous improvement of yourselves, your colleagues, our products and processes.

We are not looking for test automation engineers, as you're tasks will be more divers then that. Examples of your tasks are:

  • You setup continuous delivery pipelines and use these in your squad
  • Automate and execute functional tests with cucumber and karate

  • You use the most important ITIL processes and understand how these support the quality of your application

Dan ben jij een persoon die we graag uit willen dagen om dit bij ons te komen bewijzen. ING is ambitieus en vraagt dan ook veel van je. Het is daarom alleen maar eerlijk om daar ook veel voor terug te geven. Onze arbeidsvoorwaarden zijn goed en op een aantal gebieden zelfs onderscheidend. Naast een uitstekend salaris kun je ook standaard rekenen op een goed pensioen.
