Grey Parrot Systems is a women-owned, BEP-certified IT services firm headquartered in Naperville, IL. We deliver AI-first, governance-driven digital transformation — and we're growing.

Must-Have Skills

• 8 years of data engineering experience — proven technical leadership or lead engineer experience
• Expert-level Snowflake — architecture, schema design, query optimization, cost governance, and access controls
• Expert-level dbt — modeling, transformations, testing, documentation, incremental models, and deployment governance
• Strong Dagster — asset-based pipelines, scheduling, sensors, and alerting
• Strong Python — production-grade ETL/ELT automation and pipeline development
• Expert-level SQL — complex queries, window functions, CTEs, and performance optimization
• Deep data modeling — Medallion Architecture, star schema, and dimensional modeling
• Experience defining data engineering standards — coding practices, naming conventions, and documentation
• Ability to mentor and guide junior and mid-level data engineers
• Must be local to Naperville, IL — on-site / hybrid availability required

What You'll Do

• Own data engineering architecture and delivery — setting technical direction and governing standards
