• AI fluency: you use AI coding tools daily and check their output carefully, especially for SQL, schema changes and anything that affects data correctness.

• Build the query layer behind our customer-facing data API, and give others access through Athena
• Evaluate technical approaches, measure performance and cost, and document the choices you make
• Migrate existing dashboards, reports and finance extracts onto the new platform
