  • Collaborate closely with Data Analysts, Architects, and Software Engineers to ensure data is highly accessible, reliable, and tailored to business needs.

  • Ensure strict data security, governance, and compliance with industry best practices and GDPR regulations throughout the entire lifecycle.

  • Monitor and troubleshoot data infrastructure performance, proactively identifying and resolving bottlenecks to maintain maximum efficiency.

  • You are highly proficient in programming languages such as Python, Scala, or Java, and you possess an advanced mastery of SQL.

  • You have solid, hands-on experience with modern data processing frameworks (like Apache Spark or Kafka) and cloud platforms (AWS, GCP, or Azure).

  • You are comfortable with DevOps best practices, version control (Git), CI/CD pipelines, and containerization/infrastructure tools (Docker, Kubernetes, Terraform).

  • Endowed with excellent problem-solving skills, you are rigorous and always eager to explore new open-source data technologies.

  • Your collaborative spirit, adaptability, and fluency in English (along with French or Dutch) make you an ideal partner to tackle ambitious challenges in our international Brussels context.
