What you will do

We are running a system modernization initiative to migrate a legacy enterprise application built with PowerBuilder to a modern Java-based platform for a big US insurance company.

The main objective of this role is to analyze, extract, validate, and support the migration of business logic from PowerBuilder, as well as to build Python-based tools and services that enable data migration, logic validation, automation, and integration between the legacy and new systems.

Requirements

MUST

PowerBuilder:

• Strong hands-on experience with PowerBuilder in enterprise or legacy systems
• Deep understanding of DataWindows, event-driven logic, and database interaction
• Ability to analyze complex, poorly documented legacy codebases
• Experience supporting modernization or migration projects

Python:

• Strong experience with Python for scripting, automation, and backend services
• Experience with data processing, validation, and comparison frameworks
• Familiarity with SQL and database connectivity from Python
• Ability to build reliable tools used by other engineering teams

General Technical Skills:

• Strong SQL skills (Oracle, PostgreSQL, SQL Server, or similar)
• Experience working with large datasets and business-critical systems
• Ability to document legacy logic clearly and unambiguously

NICE TO HAVE

• Prior experience in PowerBuilder migration projects
• Experience building migration or reconciliation frameworks
• Knowledge of batch processing, reporting, or ETL pipelines
• Familiarity with REST APIs (consumer level, not necessarily implementation)
• Experience working in parallel-run or phased cutover migrations
• Experience in working with Rocket UniVerse DB
