• Deep understanding of Spark architecture, distributed data processing, performance tuning, partitioning, and optimization.
• Experience building highly scalable batch and streaming data processing solutions.
• Strong understanding of data modeling, data warehousing concepts, and modern data architectures.
• Experience supporting production environments, monitoring data pipelines, and troubleshooting complex data issues.

Preferred Qualifications:

• Experience with Databricks Workflows, Delta Live Tables (DLT), Unity Catalog, and Structured Streaming.
• Experience with Kafka, Airflow, or cloud-native orchestration frameworks.
• Experience implementing CI/CD pipelines using GitHub Actions, Jenkins, or Azure DevOps.
