Lead Data Engineer

Key Responsibilities

•Pod delivery — Own end-to-end delivery for the data engineering pod, including planning, execution, quality, and operational readiness.

•Lakehouse architecture — Own the design and evolution of the NBA Databricks Lakehouse, including Bronze, Silver, and Gold layer standards, data lineage, and governance patterns.

•Feature platform ownership — Lead the design and operation of Gold-layer feature tables and reusable data products that support model training, scoring, reinforcement learning, and decision intelligence workloads.

•Streaming and event architecture — Design and implement Kafka- and Spark Structured Streaming-based ingestion and processing patterns that enable near real-time decision-making.

•Data quality and observability — Establish platform-wide standards for data validation, monitoring, lineage, reconciliation, alerting, and operational visibility; treat data quality issues as production incidents.

•Performance and optimization — Drive optimization of Spark workloads, Delta Lake storage patterns, partitioning strategies, and query performance to support enterprise-scale volumes efficiently.

•Data governance — Ensure compliance with PHI, HIPAA, auditability, retention, and governance requirements through Unity Catalog, lineage tooling, and secure data management practices.

•Team leadership — Lead and mentor engineers and contractors; conduct code reviews, establish engineering standards, and drive adoption of best practices across the pod.

•Cross-team coordination — Partner with Decision Intelligence, Data Science, AI Engineering, and Platform Engineering teams to ensure reliable, governed, and performant data delivery throughout the NBA ecosystem.

•Experience with Kafka, event streaming architectures, and real-time feature engineering pipelines.

•Experience designing feature stores, feature-serving architectures, and model-data integration patterns.

•Familiarity with Azure Data Factory, Azure Event Hubs, Azure Data Lake Storage, and broader Azure data platform services.

•Experience implementing data observability and quality platforms such as Great Expectations, Monte Carlo, or equivalent solutions.

•Experience integrating large external datasets including CMS, CDC, USDA, consumer, behavioral, or social determinants of health data sources.

•Background in healthcare, insurance, or another regulated industry with PHI/HIPAA requirements.

We build with modern AI development tools (such as Claude and GitHub Copilot) and expect everyone on the team to use them to work faster and at higher quality.
