Senior Databricks Engineer

Databricks Platform Engineering

• Design, build, and maintain Databricks workspaces, clusters, and compute pools across dev/test/prod environments.
• Configure and manage Databricks Unity Catalog for data governance, access control, fine-grained permissions, and data lineage.
• Optimize cluster configurations - instance types, auto-scaling policies, spot/preemptible nodes - for cost and performance.
• Implement workspace-level best practices: folder structures, access controls, secret management (Databricks Secrets / Azure Key Vault / AWS Secrets Manager).
• Manage Databricks jobs, workflows, and multi-task job orchestration with dependency management. Delta Lake & Lakehouse Architecture
• Design and implement Delta Lake tables with appropriate partitioning, Z-ordering, and file compaction (OPTIMIZE / VACUUM).
• Build Medallion Architecture (Bronze / Silver / Gold) layers for structured data lake organization.
• Implement Delta Live Tables (DLT) pipelines for declarative, reliable ETL/ELT with built-in data quality expectations.
• Manage schema evolution, table versioning, time travel, and Change Data Feed (CDF) for incremental processing.
• Design data lakehouse patterns integrating Delta Lake with external systems (Kafka, ADLS, S3, GCS).

Data Pipeline Development (PySpark / SQL)

• Develop scalable batch and streaming data pipelines using PySpark, Spark SQL, and Delta Lake.
• Build structured streaming pipelines for real-time ingestion from Kafka, Event Hubs, and Kinesis into Delta tables.
• Write optimized PySpark transformations leveraging broadcast joins, adaptive query execution (AQE), and dynamic partition pruning.
• Create reusable transformation libraries, utility frameworks, and pipeline templates for team productivity.
• Implement robust error handling, retry logic, and dead-letter queue patterns in production pipelines. MLflow & AI/ML Workloads
• Set up and manage MLflow tracking servers, experiment registries, and model lifecycle management on Databricks.
• Support data scientists and ML engineers in deploying model training and inference workloads on Databricks clusters and GPU instances.
• Build feature engineering pipelines using Databricks Feature Store for reusable, versioned ML features.
• Enable GenAI workloads - LLM fine-tuning, RAG pipeline development, and vector search (Databricks Vector Search / Mosaic AI).
• Implement MLOps practices: model versioning, A/B testing, model serving via Databricks Model Serving endpoints. Cloud Integration & DevOps
• Integrate Databricks with cloud-native services: Azure Data Lake Storage (ADLS).
• Build and maintain CI/CD pipelines for Databricks notebooks and jobs using Azure DevOps, GitHub Actions, or GitLab CI.
• Implement Databricks Asset Bundles (DABs) or Terraform for infrastructure-as-code (IaC) deployment of Databricks resources.
• Manage data ingestion using Auto Loader, COPY INTO, and partner integrations (Fivetran, dbt, Airbyte).
• Monitor pipeline health, cluster utilization, and costs using Databricks system tables and cloud cost management tools. Governance, Security & Optimization
• Implement row-level security, column masking, and dynamic data views using Unity Catalog policies.
• Ensure data quality enforcement using Delta Live Tables expectations and Great Expectations integrations.
• Conduct performance tuning - query plan analysis, caching strategies, Photon engine enablement.
• Maintain data cataloging, metadata management, and data lineage tracking within Unity Catalog.
• Document architecture decisions, runbooks, and operational guides for Databricks workloads.
