Key Responsibilities

Data Engineering and Development

• Design, build, test, deploy, and maintain scalable ETL and ELT pipelines using Databricks, PySpark, Spark SQL, Python, and SQL.
• Develop reusable ingestion and transformation frameworks for structured, semi-structured, and streaming data.
• Implement batch, incremental, change-data-capture, and streaming processing patterns.
• Build and maintain Delta Lake tables using medallion architecture across Bronze, Silver, and Gold layers.
• Develop dbt models, tests, macros, packages, documentation, and incremental processing patterns.
• Create and maintain Apache Airflow DAGs and Databricks Workflows with dependency management, retries, alerting, and operational controls.
• Integrate data from APIs, databases, files, event streams, and cloud data services.
• Produce technical designs, mapping specifications, lineage documentation, deployment instructions, and operational runbooks.

Performance, Reliability, and Data Quality

• Tune Spark workloads, joins, partitioning, file sizes, caching, cluster configurations, and query plans.
• Apply Delta Lake optimization techniques, including compaction, data skipping, clustering, retention, and vacuum controls.
• Implement automated data quality, reconciliation, schema validation, observability, and freshness checks.
• Monitor pipeline health and resolve failures, performance degradation, data defects, and service-level breaches.
• Perform root-cause analysis and implement durable preventive measures.
• Support release readiness, production cutover, incident resolution, and ongoing platform operations.
• Improve compute utilization and cost efficiency across batch and streaming workloads.

Governance, Security, and Delivery Practices

• Apply Unity Catalog standards for catalogs, schemas, tables, views, lineage, classification, and controlled access.
• Implement secure handling of credentials, secrets, personally identifiable information, and regulated data.
• Contribute to CI/CD pipelines, automated testing, code-quality checks, and environment promotion.
• Use Git-based development, peer reviews, branching standards, and release-management practices.
• Collaborate with platform engineers to deploy data assets through Terraform and Databricks Asset Bundles where applicable.
• Follow enterprise architecture, security, data-governance, and regulatory requirements.

Collaboration and Mentoring

• Partner with architects, product owners, analysts, data scientists, governance teams, and business stakeholders.
• Translate business requirements into scalable data models, pipelines, and technical work packages.
• Conduct code reviews and enforce engineering, documentation, testing, and support standards.
• Mentor junior and mid-level engineers and share reusable patterns and best practices.
• Communicate delivery status, risks, dependencies, and technical trade-offs clearly.

Required Qualifications

• Typically 7 10 years of data engineering, data warehousing, or distributed data-processing experience.
• Strong hands-on experience with Databricks, Apache Spark, PySpark, Delta Lake, Python, and advanced SQL.
• Experience building production-grade ETL and ELT pipelines for large datasets.
• Experience with dbt Core or dbt Cloud, including models, macros, tests, documentation, and incremental processing.
• Experience with Apache Airflow, Astronomer, Databricks Workflows, or comparable orchestration platforms.
• Experience with Unity Catalog, data lineage, role-based access, and data-governance controls.
• Experience with cloud data services on AWS, Azure, or Google Cloud.
• Working knowledge of Git, CI/CD, automated testing, monitoring, and production-support practices.
• Strong troubleshooting, communication, collaboration, and technical-documentation skills.

Preferred Qualifications

• Experience in banking, financial services, insurance, asset management, risk, compliance, or another regulated industry.
• Experience modernizing Hadoop, legacy data warehouses, or traditional ETL platforms.
• Experience with Kafka, Structured Streaming, Auto Loader, Delta Live Tables, or Lakeflow Declarative Pipelines.
• Familiarity with Terraform, Databricks Asset Bundles, cloud networking, IAM, secrets management, and infrastructure automation.
• Databricks Data Engineer Associate or Professional certification.
• Experience delivering data reconciliation, regulatory reporting, test automation, and audit-ready controls.
