Key Responsibilities

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 Excellent 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.
