How do you make our customers happy?

At, IT is all about driving the best possible shopping experience for 10 million Dutch and Belgian customers. From finding that cute gift for a loved one, to ordering the next size diapers for junior – there’s a personal story behind every purchase. We already have real time measurements in place to grasp how customers and partners interact with our platform, but we want to greatly expand on existing tooling, so we can make even better-informed business decisions and provide customers with even more relevant (and inspiring!) information. It’s up to you to turn that into a reality…

Your responsibilities as Software Engineer Streaming Data

Streaming data has a bright future at And as our Software Engineer Streaming Data you make sure that future is so bright we have to wear welding masks to work! Together with your team – all talented, all enthusiastic, all willing to share – you develop a truly scalable streaming platform. A daunting challenge, because the amount of data we process is enormous. And no, that’s not idle marketing talk: we process TBs per day, so monitoring and optimizing the performance of our data cloud infrastructure is key.

You are responsible for developing and maintaining the real time streaming stack: libraries, services, streaming, processing and – sorry, but yes! – documentation. You also safeguard the structure of measurements and make those available and meaningful for the teams that use them. Speaking of teams; you will support and consult other teams in applying our tech to increase the resolution of what we measure. As far as tooling goes, your stack includes Kafka, Flink, Beam/Dataflow, Big Query, Kubernetes and Google Cloud Platform. We prefer to write in and/or use Spring, Java, Kotlin and Python, but if you want to wow us with a great alternative, we’re open to it!

3 reasons why this is(n’t) for you

  • Because you have experience with real time data streaming and software engineering or you’re a real expert in either of those in cloud environments
  • Because your development skills are undisputed. If your Kotlin or Java needs some dusting off, your engineering prowess will get you (back) up to speed quickly
  • Because you want to contribute to the growth of colleagues and for them to reciprocate; your feedback is constructive, and you are keen to know how others perceive what you do
  • Business considerations are not your problem; #letthemeatcode
  • You detest Agile and never take the pragmatic route to anywhere
  • Your 6 years of experience consists of one year repeated 5 times. (In truth, we only care about your skill level and potential, not how long it took you to practice)
