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 exceptional objects such as these every day. 

Catawiki is the leading online marketplace to buy and sell special objects. We offer over 75,000 special objects in auction every week — each reviewed and selected by one of Catawiki’s hundreds of in-house experts specialised in Art, Design, Jewellery, Fashion, Classic Cars, Collectables and many more.

We've sold 10 million unique items to date and it’s our mission to become the world’s most popular auction destination for special objects.

We’re an innovative, pioneering and fast-growing scale-up. If you think you can make a difference to our team, go ahead and apply.

  • Help develop tools and update product data

  • Master’s degree in Library and Information Sciences, Knowledge Management, Information Management, or equivalent professional experience
  • Proven skills in data retrieval techniques: comfortable with spreadsheets, ability to interpret charts and data points in relation to their context, ideally experience with extracting data from self-service BI tools (Looker, Google Data Studio, Tableau, Amplitude etc) and make sense out of it. Bonus if experience with SQL
  • Experience working with catalog and classification systems and creation of thesauri
  • Excellent English language skills. Proficiency in one or more European languages (e.g. German, French or Italian) is a bonus
  • Excellent communication and interpersonal skills. Comfortable working with diverse groups of stakeholders
  • Ability to prioritise activities in a changing environment, and to remain calm under pressure
  • Self-motivated and decisive
  • Ability to quickly understand complex processes and communicate them in simple language
