• Lead the adoption of Snowflake Cortex for AI-native use cases: LLM-powered pipelines, intelligent data agents, and automated data workflows.
• Define data modeling standards (dimensional modeling, data vault, star schema) and govern their application across teams.
• Architect and oversee scalable ELT pipelines using dbt, Fivetran, and custom connectors.
• Drive data governance, access controls, security, and cost management best practices within Snowflake.
