Data Engineering & BI/Analytics

Data Engineering & BI/Analytics

Role Summary

Moves and transforms data across the County's legacy-to-modern data landscape: legacy mainframe/file-based data conversion into target systems, enterprise BI and reporting (Power BI, Databricks, SSRS/SSIS), and Oracle-based data warehousing and financial-systems integration. Reflects a County mid-migration — still operating legacy pipelines while building a modern BI layer. Expect continued growth in Databricks/modern-stack reqs.

Core Responsibilities

• Profile, cleanse, transform, validate, and load data from legacy systems into target solutions
• Support data mapping and crosswalk analysis across organizations and vendors
• Design and develop Power BI dashboards, paginated reports, and row/object-level security
• Build and support Azure Data Factory / Databricks data pipelines and data warehouse solutions
• Develop and tune Oracle PL/SQL and SQL Server queries, stored procedures, and jobs
• Design data models using DAX/MDX across Power BI, SSAS, Databricks, or Azure Synapse
• Support data loading and integrations using REST APIs and EPM Automate (for Oracle PBCS/EPM variants)
• Document extraction logic, validation rules, and data-retention/compliance requirements
• Facilitate knowledge transfer so business users can work independently with converted data
