• Lead integration across data sources: MySQL, BigQuery, Redis, Kafka, GCP Storage, and API Gateway.
• Implement CI/CD for data pipelines using Git, dbt, and automated testing.
• Define data quality checks and auditing pipelines for ingestion and transformation layers.
• 2. Leadership & Collaboration
• Mentor and guide junior data engineers on data modeling, performance tuning, and Snowflake best practices.
• Partner with Data Science, ML, and Backend teams to productionize machine learning features in Snowflake.
• Work closely with Legal, Security, and Infrastructure teams to ensure compliance, privacy, and governance of user data (PII).
• Collaborate with the Director of Data Platforms and product stakeholders to translate business requirements into technical specifications.
• 3. Performance & Scalability
• Tune algorithm performance.
• Establish data partitioning, clustering, and materialized views for fast query execution.
• Build dashboards and monitors for pipeline health, job success, and data latency metrics (e.g., via Looker, Tableau, or Snowsight).
• 4. Governance & Best Practices
• Establish and enforce naming conventions, data lineage, and metadata standards across schemas.
• Lead code reviews, enforce documentation standards, and manage schema versioning.
