•Own and evolve Apache Airflow as a platform, driving version upgrades, configuration, and architectural best practices.
•Implement monitoring, alerting, resource tracking, and automated data quality checks, diagnosing pipeline issues at the root cause.
•Take active responsibility for the data platform's costs (e.g., Snowflake credits). Optimize warehouse performance and build systems to track compute usage down to the individual user level, ensuring all ~30 data champions are operating efficiently and accountable for the costs they generate.
