Cloudera Data Engineer

Key Responsibilities

• Design, build, and optimize end-to-end ETL/ELT pipelines in Databricks using Delta Lake, Delta Live Tables (DLT), Auto Loader, PySpark, and Spark SQL for high-volume, multi-format partner ingestion.
  
• Implement Medallion (zoned) architecture – Raw (bronze), Standardized (silver) with advanced validation, quarantine/reject logic, schema enforcement, and Curated (gold) consumer-ready datasets optimized for downstream COB/PI analytics.
  
• Leverage Unity Catalog for data governance, access control, lineage, and secure multi-tenant data management.
  
• Develop incremental processing, change data capture (CDC), backfill strategies, late-arriving data handling, and partitioning/optimization techniques (Z-Ordering, Liquid Clustering, Auto-Optimize) to eliminate performance bottlenecks.
  
• Build robust data quality frameworks using Delta constraints, expectations, and monitoring to ensure clean, reliable data for downstream consumption.
  
• Create production-grade Databricks Workflows, Jobs, and orchestration for reliable batch and near-real-time processing using Spark Structured Streaming.
  
• Perform data profiling, mapping, reconciliation, and performance tuning of large-scale Spark jobs on Databricks clusters.
  
• Collaborate with Senior Data Architect and Data Modeller to translate target-state lakehouse design into implementable, testable increments.
  
• Deliver shippable, production-ready increments in Agile sprints within the implementation window, including CI/CD integration, unit/integration testing, and operational runbooks.
  
• Establish comprehensive observability using Databricks Lakehouse Monitoring, SQL Alerts, and dashboards for pipeline health and SLA compliance.
  

Required Qualifications & Experience

• 8+ years of hands-on data engineering experience
  
• 5+ years building enterprise-scale solutions on Databricks (Unity Catalog, Delta Lake, Delta Live Tables)
  
• Proven track record delivering Medallion/zonal lakehouse architectures in production
  
• Strong experience with high-volume, regulated data workloads (claims, financial, or healthcare data highly preferred)
