Senior IBM i Application & Data Migration Specialist

Role Description

The Senior IBM i Application & Data Migration Specialist will serve as the primary technical resource for a critical legacy IBM i environment during the organization's transition to a new Third Party Administrator (TPA). This individual will fill a significant knowledge gap created by the departure of a long-term application administrator and will take ownership of understanding, stabilizing, documenting, and ultimately helping transition the business-critical functionality and data contained within the NMIC400/Basys environment.

This is not simply an IBM i administration assignment. The successful consultant must be capable of entering an environment with incomplete documentation and limited institutional knowledge, independently reverse engineering custom applications and data structures, and determining how critical pension and benefits administration processes actually operate. The individual will support current production needs while simultaneously uncovering the application logic, historical data, reports, interfaces, dependencies, and operational procedures required for the future-state TPA transition.

Success requires deep IBM i technical expertise, strong RPG/RPGLE and DB2 for i knowledge, hands-on data migration capabilities, and the curiosity and judgment to solve problems when there is no existing playbook.

Qualifications

• Extensive hands-on experience supporting custom IBM i, AS/400, or iSeries applications.
• Deep knowledge of RPG, RPGLE, CL, DB2 for i, Query/400, batch processing, job scheduling, IBM i commands, legacy reporting, and application-level troubleshooting.

Requirements

• Become the Technical Authority for the NMIC400/iSeries Environment.
• Stabilize Legacy Application Operations Throughout the Transition.
• Deliver Accurate and Traceable Legacy Data for the New TPA.
• Preserve Critical Business Logic, Reporting, and Institutional Knowledge Before Platform Retirement.
• Enable an Orderly Transition and Retirement of the Legacy Platform.

Benefits

• Opportunity to become the technical bridge between a mission-critical legacy platform and the organization's future-state benefits administration environment.
• Ownership of a complex legacy modernization initiative spanning application discovery, reverse engineering, data architecture, migration, reporting, operational support, and platform retirement.

Critical Subtasks

• Discover and Map the Legacy Environment.
• Stabilize and Support Critical Production Operations.
• Reverse Engineer Business Logic and Reporting.
• Extract, Map, Validate, and Reconcile Migration Data.
