Senior Data Engineer

You support our Business Analysis and Data Science teams through your technical expertise and passion for data.

    Pros and cons

    • You design and build data processing clusters using Airflow, Dataproc and Dataflow
    • You pair on stories and defend our Tech Principles
    • You coach your colleagues and present demos
    • You will support Coolblue going Real-Time
    • We have so much data, it might make you dizzy


    After your morning Scrum standup, Cindy sends you a Pull Request to speed up the transfer of data from the ERP system using a new messaging system. You review it together and then merge the code. After that, you join Manuel, the Product Owner, who wants to discuss the requirements for the new process that will provide new insights about our customer Journey.

    Just before lunch, you pass by Jingting, a data scientist who is working on a new Machine Learning algorithm which can forecast warehouse stock. You help her moving some data to BigQuery. You invite her to have lunch together with your team. On the way back, you share your concerns about the Google Adwords ingest process with Rafael. It's losing records, so you want to refactor some of the python code. You add a few automated tests, send the Pull Request to your teammate, Benedetto, for review and at 16:30, the improvements are automatically deployed via our continuous integration pipeline. By 17:30, you're done for the day and, together with your team members, head to the bar for a drink.
