• Simplify and automate data flows across multiple source systems, contributing to digitalization through AI and automation.
• Build automated validation, testing and reconciliation controls to ensure high data quality and auditable outputs.
• Investigate complex data issues, identify root causes and ensure the technical and logical consistency of calculation results.
• Support data governance through ownership, documentation, lineage, Unity Catalog and secure access controls.
• Contribute to CI/CD practices, including version control, automated testing, deployment and release management.
• Analyse complex data, support scenario modelling and develop dashboards and reporting solutions.

Required profile

• Degree in Computer Science, Management of Information Systems, Data Science or equivalent professional experience.
• 2-3 years of experience in Data Engineering or a related field (software engineering, data science, data analytics).
• Proven experience with data platforms such as Databricks or similar (Snowflake, Microsoft Fabric, Google BigQuery or similar).
• Proven experience with Azure services including Data Factory, Storage Account and Key Vault.
• Fluency in English; German and/or French are an advantage.
• Preferred: Data Engineering certifications and dbt experience.

Required skills

• SQL, Python and PySpark
• Code versioning and DevOps tools such as Azure DevOps or GitHub, and CI/CD practices
• Familiarity with data governance concepts and tools (data management, lineage, access controls, row-level security) is an advantage
