Full Job Description

Job Title:Senior Database Developer / Engineer (SQL Server to Oracle Migration)

Location: Pittsburgh, PA

Duration :6 Months Contract

Role Summary
We’re looking for a senior database engineer with strong experience in SQL Server, Oracle,
and SSIS/SSRS to support a critical migration initiative. This is a hands-on role focused on
converting database logic, handling dynamic SQL, migrating data, and ensuring the system
runs reliably on Oracle while maintaining existing ETL processes and reports.

Key Responsibilities
Database Migration & Conversion
 Work on end-to-end migration from SQL Server to Oracle
 Convert schemas, tables, indexes, views, and functions to Oracle-compatible formats
 Identify and resolve platform-specific differences between SQL Server and Oracle
 Ensure database design aligns with Oracle best practices

Stored Procedure & Query Conversion (Core Area)
 Convert complex T-SQL stored procedures and queries into PL/SQL
 Work extensively with dynamic SQL conversion and refactoring
 Handle differences in:
o Transactions and error handling
o Temporary tables and session-level objects
 Refactor logic where direct conversion is not feasible
 Ensure converted code is stable, optimized, and easy to maintain

Data Migration
 Support migration of large datasets with controlled downtime
 Design and implement efficient data movement strategies
 Validate and reconcile data between source and target systems
 Handle edge cases to ensure data accuracy and completeness

ETL & Reporting (SSIS / SSRS)
 Work on existing ETL and reporting layers with no major redesign

 Update and validate:
o Connection managers to point to Oracle
o Inline queries and stored procedure calls
 Ensure compatibility of ETL workflows and reports with Oracle backend
 Perform end-to-end validation to confirm processes run as expected

Performance Tuning
 Analyze and optimize query performance in Oracle
 Compare behavior between SQL Server and Oracle execution
 Trouble shoot issues observed after migration
 Tune indexes, execution plans, and database design as needed

Testing & Validation
 Support unit, integration, and system testing cycles
 Help identify and fix issues discovered during testing
 Work closely with QA and business teams to validate outcomes

Cutover & Production Support
 Participate in migration rehearsals and production cutover
 Support deployment and provide hyper care after go-live
 Troubleshoot and resolve production issues quickly

Required Skills & Experience
 10+ years of experience in database development/engineering
 Strong hands-on experience in:
o SQL Server (T-SQL, stored procedures, dynamic SQL, SSIS, SSRS)
o Oracle (PL/SQL, performance tuning)
 Solid understanding of differences between SQL Server and Oracle
 Experience working on database migration or modernization efforts

Nice to Have
 Experience with large-scale data migration

 Familiarity with tools like Oracle Data Pump, Goldengate, or similar
 Exposure to ETL and reporting tools (SSIS, SSRS)
 Experience in financial or regulatory systems

What We’re Looking For
 Strong focus on logic-driven conversion, especially dynamic SQL handling
 Comfortable working in critical migration paths with dependencies
 Strong troubleshooting and analytical mindset
 Ability to collaborate across DBA, development, and QA teams

Success in This Role Looks Like
 Stable and performant Oracle environment post-migration
 Smooth migration with no disruption to ETL and reporting
 Clean cutover and quick stabilization during hyper care
