Job description

Do you love making data speak to solve real business challenges? Within our Data team, you turn complex data into clear decision-making levers for our business teams. Your work directly guides our strategy to create value every day.

  • Translation of business needs: you listen to team requests, challenge assumptions, and define precise analytical questions.
  • Exploration and cleaning data: you identify the best internal and external data sources, check their quality, and prepare data using SQL, Python, or dbt.
  • Building concrete solutions: you create reusable metrics, design prototypes, and test your hypotheses with statistical models.
  • Explaining your analysis: you explain complex results using visual storytelling on Tableau or other BI tools to convince non-technical colleagues.
  • Working as a team: you document your methods on Git, share best practices with your peers, and care for your own well-being as much as your teammates.

Requirements

You are passionate about digital, love numbers, and embody our active values every day.

Rigorous and proactive, you organize your work independently, self-motivate, and naturally propose hypotheses and actionable recommendations.

You communicate clearly, you can break down complex findings into simple, synthetic reports for non-technical teammates. Having a good understanding of the business and a good critical thinking, you encounter an operational problem and immediately spot the data needed to solve it.

Moreover,

  • You hold a Bachelor’s or Master’s degree in engineering, informatics, or statistics with a specialization in data engineering, big data, or data science and you bring at least 3 years of hands-on experience in a data analyst role.
  • You master data languages: you navigate SQL and Python and R with ease.
  • You bring insights to life with high-impact dashboards using Tableau, Looker Studio, or Power BI.
  • You bring hands-on experience with cloud environments like AWS, GCP, or Azure.
  • A real plus: You are familiar with dbt, DataBricks, have knowledge on Gen AI, on A/B testing strategies and logic and you are product builder (app, assistant)
  • You are fluent in French with a solid level in English for our international context (basic Dutch is a plus).
