Data Engineer Sr (Databricks)

Roles & Responsibilities

• Develop Databricks notebooks, jobs, and workflows to replicate and enhance DB2/Guidewire-based pipelines and transformations.
• Implement Delta Lake tables and patterns (bronze/silver/gold, ACID, time travel, schema evolution) for migrated data.
• Integrate Databricks with AWS/S3 or Azure ADLS, ADF/Synapse, Key Vault, and Snowflake as required.
• Optimize Databricks clusters, jobs, and queries for performance and cost.
• Implement incremental loads, CDC patterns, and batch schedules for large datasets.
• Collaborate with Snowflake and dbt teams to ensure consistent data models and data contracts.
• Participate in data validation and reconciliation between DB2 400 / Guiderwire and Databricks outputs.
• Follow coding standards, version control, and CI/CD practices using Git/Azure DevOps.
• Provide defect fixes and support during SIT/UAT and post go-live stabilization.

Experience :

Legacy Demystification & Ingestion (DB2/400 & Guidewire) 8+ years of experience in databricks with understanding complex legacy data models and getting that data into the cloud:

• Extracting DB2/AS400: Experience with Change Data Capture (CDC) or scheduled batch extractions from DB2 into cloud storage. Involves working through JDBC connections, mapping table dependencies, and re-platforming legacy SQL to distributed computing standards.
• Handling Guidewire Data: Integrating with Guidewire Cloud Data Access (CDA) or InsuranceSuite to replicate complex P&C (Property & Casualty) insurance schemas. Senior engineers parse these highly normalized operational databases and transform them into analytical-friendly schemas in the cloud.

1. Architecture & Pipeline Development

The core of the experience involves transitioning these legacy, row-based stores into a scalable Medallion Architecture (Bronze, Silver, Gold layers):

• Delta Lake Optimization: Using Databricks and Apache Spark to build ETL/ELT data pipelines with ACID transactions. Senior engineers handle schema evolution, upserts, and slowly changing dimensions (SCD Type 2).
