Job Description

Who we are

A piece of the moon, a complete dinosaur skeleton, the Pope's hat, the world's smallest book - at Catawiki, we come across extraordinary objects such as these every day.

As Europe’s fastest growing online auction platform, our mission is to make special objects available to everyone. In fact, 14 million users are buying and selling on Catawiki every month. This means we are continually growing and always on the lookout for new talent!

Born and raised in The Netherlands, we started in 2008 as a platform where collectors could manage their collections online. Yet, times change, ideas evolve, and in 2011 we hosted our first online auction and we haven’t looked back since! We’ve now grown to 450 Catawikians working across 7 international offices and are proud to have maintained our start-up mentality.  

Our Data Story

With thousands of active lots every day, hundreds of thousands of daily bids, millions of users, and countless marketing campaigns, the Catawiki platform generates vast amount of data every day. This data is being collected and stored in the Data warehouse, which is used extensively by our team of 10 analysts and data scientists. There are also hundreds of active internal users of our Web interface to the Data warehouse.
As Catawiki grows and produces more data, our Analysts would like to perform even more sophisticated analyses, our Data Scientists want more data,  and yes, Product owners want more dashboards! With this in mind, Catawiki is building a new distributed data platform using tools from the Hadoop ecosystem that can accommodate the rapidly growing amount of data and requirements of analysts, data scientists, and product owners.
We have started streaming event data and writing data pipelines in Apache Airflow that transform this data with Apache Spark, and now Catawiki needs more Data Engineers to help us tackle the challenge of bringing even more data sources into our platform and transforming and organizing this data for analysis and consumption by other applications. It’s a big challenge but one that we’re really excited about solving.

  • Explore new ways of transforming and analyzing data and continuously expand and improve the performance of our data pipelines.
