Java Developer (Universe DB, SQL)

Project description

We are executing a phased modernization program to migrate a legacy enterprise system built on Rocket UniVerse (UniVerse / UniData) database technology and a PowerBuilder client-server application stack to a modern Java-based platform with a relational SQL backend for a large US insurance company.

As part of this initiative, we are looking for a Senior Data Migration Engineer to play a key role in the data and data-driven logic migration. The primary responsibility of this role is to design and implement Java-based tooling for data extraction, transformation, validation, and reconciliation, ensuring that the migrated data in the target Database environment is accurate, consistent, and functionally equivalent to the legacy system.

This is a migration-focused role. Success in this position requires strong experience with Universe DB / MultiValue data models, combined with the ability to build robust, repeatable migration and validation components in Java within a phased or parallel-run modernization program.

Responsibilities

This role focuses on Java-driven migration tooling and data validation, combined with deep expertise in Rocket UniVerse.Developer will design and implement Java-based solutions to extract, transform, validate, and reconcile data and data-driven business logic from Universe DB, while also accounting for how this data is consumed and interpreted by the legacy PowerBuilder application.
