- SQL and dbt Mastery: Track record of designing modular, multi-layer dbt projects and writing clean, maintainable SQL.
- Pipeline Design & Orchestration: Ability to design scalable pipelines from first principles using workflow orchestration tools like Airflow.
- Python Proficiency: Experience writing clean, testable Python for pipeline logic, custom operators, and tooling.
- Feature Engineering for ML: Strong understanding of point-in-time correctness, train/serve symmetry, and data freshness bounds.
- Cloud Infrastructure & Optimization: Experience managing query performance and cloud costs in BigQuery or comparable environments.
- Infrastructure as Code: Hands-on experience defining cloud infrastructure programmatically using tools like Terraform or Pulumi.
- Reliability Engineering: Commitment to treating missed data SLAs as business impacts, adding preventative tests, and writing post-mortems.
- Partner Collaboration: Ability to translate requirements into data contracts and communicate schema changes to internal partners.
- Advanced Data Capabilities (Bonus): Familiarity with streaming frameworks, LLM fine-tuning pipelines, or managed ML training platforms.
