    Description Junior Python Developer

    You start your Monday with a weekly stand-up with the marketing bidding team. This week, you’re working with Bidding Expert Rob and Data Scientist Daan. Together, you’ll focus on the automatic cancellation of marketing investments in case of high demand in the warehouse. The keyword bids that Data Science has calculated are ready to be added to the Google Ads API.

    Another project you’re working on is the automatic creation of product-specific banner advertisements. This may sound tough, but luckily, you’re not on your own. Your Google contact is visiting the office with good news: we’re part of a beta-test, which allows us to use structured data files to create campaigns in bulk. That’ll save lots of manual work!

    Later on in the week, you’re meeting with your Data Engineering colleagues. They really know their stuff and teach you how to juggle your data. After all this data magic, it’s time for Friday drinks.


    Your specifications

    • You have a commercial or technical bachelor’s degree (preferably in Informatics or Business Administration).

    • You can program in a programming language.

    • You want to learn everything there is to know about Python, Airflow, and Google Cloud Platform, and how you can use these in the world of online marketing.

    • You can explain how you execute your job, in English, and why it’s a good approach.

    • You’re curious and want to investigate what users want and why they want it.

    • You examine everything down to the tiniest details, and you’re not easily frustrated or stressed by bugs and errors.

    Included by default

    • Money.

    • With over 30 training courses in our own Coolblue University, you can become a little better every day.

    • 25 leave days. As long as you promise to come back.

    • A discount on all our products.

    • Travel allowance and a retirement plan.

    • Room for new initiatives and ideas. We’re always open to those. Doesn’t matter if you’ve worked with us for a week, a month, or a year.

    • A picture-perfect office at a great location. You could crawl to work from Rotterdam Central Station. Though we recommend just walking for 2 minutes.

    • Working together in an international environment with colleagues from the Netherlands, Brazil, Spain, Serbia, the US, and Italy, among others.
