Close “What I look forward to most every week are the office days with the team. When we brainstorm funny slogans together or enjoy a game of pool during the break, the working hours fly by.” Rebekka

Does Coolblue offer a hybrid workplace?

Working at the office makes us happy, that’s why we are working partly from home and partly from the office.

Can I live outside the Netherlands and still work in the Tech department of Coolblue?

No, it’s not possible to work from abroad as a Tech colleague. We like collaborating in a digital way, but over this last year we’ve seen that doing a retrospective, a pair-programming session, or grabbing a drink in real life is much more fun. That’s why we like everybody to be in the Rotterdam office at least 4-8 days a month on average. Together with your manager, you decide how often you and your team really meet in the office.

Besides that it’s much more fun to see each other in real life, there are also some tax regulations that make it hard to work from abroad.

For a lot of vacancies, we have the possibility to help you (and your family) to relocate to the Netherlands. Visit our for more information about moving to the Netherlands.

How often do I go to the office?

Together with your manager, you decide how many days you and your team will be in the office. On average, this will be at least 4-8 times a month.

Do you help new colleagues relocate?

Yes, we do this for most vacancies. If the vacancy you’re interested in has a relocation sign on top, it means we’ll help you (and your direct family) to relocate. You can find more information on our

Do I need to live in Rotterdam when I move to the Netherlands?

No, that’s not necessary. The Netherlands is a small country, so if you want to live in Amsterdam, Utrecht, or Tilburg, that’s okay. As long as you are able to meet your team in the Rotterdam office around 4-8 times a month, you can live wherever you want.

Can I keep developing myself?

Coolblue University : learning at Coolblue, in a different way.

With over 30 training courses in our own Coolblue University, you can get a little bit better every day. At Coolblue, we go back to school sometimes. But not by sitting there quietly and just listening. The training courses aren't boring, but interactive. You have to do exercises and have discussions with others. At the Coolblue University, we choose what we want to learn, so we can continue to develop en become real experts. For example, a Delivery Driver needs different training courses than a Customer Service Employe and a starter needs different courses than a manager.
