Essential functions
* Ingestion & Standardization (Raw/Bronze): Design and implement batch/near-real-time ingestion pipelines from Oracle and other sources into Azure Fabric, managing optimization (columnar format, temporal partitioning, PII handling).
* Quality & Reliability (Trusted/Silver): Define and automate rigorous data quality rules (completeness, uniqueness, consistency, timeliness), data fitness thresholds, alerts, and quarantine flows.
* Modeling & Products (Gold): Model Dimensional Data Warehouses, design domain-specific data marts, and publish reusable data products complete with schemas, data contracts, and SLAs.
* Orchestration & DataOps: Build and maintain complex Airflow DAGs with retries and backfills, while enforcing CI/CD practices (linting, code reviews, feature flags) and end-to-end observability (lineage, freshness logging).

* Strong technical proficiency in Azure Fabric (Lakehouse, pipelines/notebooks, SQL endpoints) or an equivalent Azure data ecosystem with high ramp-up capability.
* Robust experience using Oracle as a data source, including incremental extraction techniques (SCN, CDC), bulk load management, and query tuning.
* Advanced Python skills for data ingestion, transformations, and testing (highly valuing PySpark or Fabric/Spark).
* Practical mastery of modern ETL/ELT patterns (staging layers, merge/upsert operations, idempotency).

* Deep knowledge of Dimensional Modeling (Star/Snowflake schemas), data product design, and automated data quality frameworks (metrics, thresholds, alerting, metadata catalogs).
* Strong Git, CI/CD pipelines, automated testing, and Infrastructure as Code concepts (Terraform/Bicep are a plus).
