- Build ingestion pipelines using Snowpipe / Snowpipe Streaming, Streams & Tasks, Dynamic Tables, and external stages against S3.
- Develop transformation logic in SQL and dbt with version control, CI/CD, and automated testing.
- Tune performance and cost: warehouse right-sizing, clustering keys, micro-partition pruning, query profiling, result caching, resource monitors, and credit-consumption reporting.
- Implement data security and entitlements: RBAC hierarchy, dynamic data masking, row access policies, secure views, and secure data sharing across LOBs.
- Migrate legacy Oracle / Teradata / Sybase / Hadoop workloads to Snowflake, including reconciliation and parallel-run validation.
- Partner with data governance on lineage, cataloging, data quality rules, and audit/regulatory evidence.
- Support production: incident triage, root-cause analysis, SLA adherence, and on-call rotation for critical batch cycles.
- Work in Agile squads with BAs, QA, and platform engineering; participate in design reviews and code reviews.
Required Qualifications:
- 7 years in data engineering; 4 years hands-on Snowflake in a production environment.
- Expert SQL - window functions, CTEs, complex joins, query optimization, execution plan analysis.

- Orchestration: Airflow, Control-M, or Autosys.
- AWS: S3, IAM, Glue, Lambda, Secrets Manager.
- CI/CD and IaC: Git, Jenkins/GitHub Actions, Terraform or Schema change for Snowflake object deployment.

- Demonstrated Snowflake cost-governance ownership (not just development).

- SnowPro Core / Advanced Data Engineer certification.
- Prior tier-1 investment bank or large financial-services experience.
