- Implement best practices for data modeling, schema design, and pipeline fan-out strategies.
- Ensure data integrity, quality, and consistency across Medalion architectures, star schemas, and Lakehouse environments.
- Proactively identify opportunities to enhance platform scalability, efficiency, and reliability.

Success in this role requires:

- 8+ years of experience in data platform engineering or related roles focusing on infrastructure and data management.
- Deep experience with analytic query engines and platforms such as Trino (Presto), Redshift, BigQuery, and Apache Iceberg.
