Automation Support & Learning: Assist senior data engineers in testing and validating automated workflows; complete daily data query and validation, and proactively learn to take on more technical tasks over time.
Ad-hoc Data Tasks: Handle data processing and reporting requests from the Finance department and cross-functional teams as assigned, including data collation, formatting, and basic transformation tasks.
BigQuery Data Room Support: Assist the senior data engineer on the BigQuery data room project — loading and staging source data, writing and testing SQL queries and transformation logic, documenting table structures and field definitions, and running data quality checks to confirm that modelled data ties back to the source systems.
