• Advanced SQL skills and experience working with complex analytical datasets.
• Strong practical experience with dbt, including incremental models, materialisations, tests, tags and selectors.
• Proven experience optimising BigQuery performance and costs through partitioning, clustering, partition pruning and query analysis.
• Familiarity with BigQuery INFORMATION_SCHEMA and the trade-offs between consumption-based and capacity-based pricing.
• Experience with change data capture or streaming ingestion into BigQuery.
• An understanding of how BI tools and dashboard queries affect warehouse performance and cost.
• Experience with Git and automated data workflows.
• A pragmatic approach to problem-solving, with the ability to explain technical trade-offs and prioritise improvements.
