## Description

We're looking for a senior data platform architect (DBA 4) to design and run a modern cloud Lakehouse built on a Medallion (Bronze, Silver, Gold) architecture. You'll build automated ELT pipelines, design the data models behind self-service BI, and own data governance and cataloging in Alation. You'll also mentor peers and junior staff.

What You'll Do

 * Design and maintain automated ELT pipelines (SQL, Python, and cloud data tools) that move data incrementally through the Medallion layers
 * Tune queries and compute for heavy transformation workloads on modern cloud data platforms
 * Migrate legacy databases and files into automated Lakehouse ingestion pipelines
 * Set standards, schemas, and file formats (Iceberg, Parquet) for ingestion and data lake processing
 * Design dimensional models (facts, dimensions, star schemas) and semantic layers that support self-service BI
 * Build data models that handle semi-structured data (JSON, API payloads) alongside structured data, with version-controlled data contracts
 * Curate the Alation Data Catalog and map end-to-end data lineage from source systems to Gold-layer reports
 * Design data validation and quality frameworks at the Bronze-to-Silver boundary
 * Implement data warehouses, data marts, dashboards, and enterprise reporting
 * Document pipelines, architecture, and standards, and mentor team members
