• Collaborate with analytics and domain teams to translate data needs into well-modeled, trusted datasets.
• Help monitor and improve the quality, reliability, and performance of data pipelines.
• Integrate new data sources into the platform through ingestion pipelines (batch or streaming).
• Implement data tests, CI/CD validations and participate in peer reviews to ensure code quality.
• Contribute to data product development within a Data Mesh architecture.
• Participate in agile rituals and collaborate with cross-functional teams.

• 2+ years of experience in Data Engineering or a similar role.
• Strong experience with SQL and dbt, and a passion for clean, efficient code.
• Solid understanding of data modeling principles (dimensional, star schema, SCDs…).
• Experience working with big data tools like Trino, Spark, or similar query engines.
• Familiarity with batch and/or streaming pipelines, e.g. Kafka or RabbitMQ.
• Experience writing data tests and following version control workflows (e.g., Git).
