    ABOUT THE JOB
    We are looking for self-motivated, creative thinkers, people that are flexible and enjoy working in teams. Our data engineering / ETL team is responsible for the development of daily ETL processes in which large amounts of behavioral data from consumer panels are imported in our data lake.
