• Work collaboratively with business users to understand requirements, translate them into technical solutions and deliver robust, scalable data products.
• Implement CI/CD, automated testing and performance monitoring for data solutions.
• Troubleshoot and resolve performance or data quality issues across the Snowflake and BI stack.

• Hands-on experience with dbt (Data Build Tool) for data transformations.
• Proficient in SQL and Python for data manipulation and automation.
• Knowledge of Azure Data Factory or similar orchestration tools.
• Exposure to large-scale or regulated environments where accuracy and governance are critical.
