Senior IBM ; AS​/400​/iSeries) Application & Data Migration Specialist

Senior IBM i (AS/400/iSeries) Application & Data Migration Specialist

Industry: Health Plan / Benefits Administration

Location:

Fargo, ND

Employment Type:

Contract 6 Months

Primary Environment: IBM i (AS/400/iSeries), NMIC
400/Basys

Overview:
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 NMIC
400/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.

Purpose:

The strongest candidate will typically bring extensive hands-on experience supporting custom IBM i, AS/400, or iSeries applications and be comfortable entering an environment where documentation is incomplete. Deep knowledge of RPG, RPGLE, CL, DB2 for i, Query/400, batch processing, job scheduling, IBM i commands, legacy reporting, and application-level troubleshooting is important. This assignment provides the opportunity to become the technical bridge between a mission-critical legacy platform and the organization's future-state benefits administration environment.

The work will directly protect operational continuity, historical data integrity, audit readiness, and the successful transition of critical pension and benefits information to the new TPA.

The consultant will gain unusual end-to-end ownership of a complex legacy modernization initiative spanning application discovery, reverse engineering, data architecture, migration, reporting, operational support, and platform retirement. Rather than maintaining one component of an established environment, this individual will influence how decades of institutional knowledge are identified, preserved, and transitioned.

1. Become the Technical Authority for the NMIC
400/iSeries Environment.

Within the first 30–60 days, develop sufficient understanding of the NMIC
400/Basys application environment to independently support critical application functions, batch processes, interfaces, reports, data structures, and operational activities with limited reliance on undocumented institutional knowledge. Reverse engineer RPG/RPGLE programs, CL procedures, DB2 for i structures, Query/400 reporting, job schedules, and application dependencies as necessary to understand how critical pension and benefits processes operate. Identify immediate operational risks, undocumented dependencies, and areas where loss of institutional knowledge could jeopardize business continuity or the TPA transition.

Success will be measured by the ability to independently resolve routine application issues, explain critical system dependencies, support business information requests, and provide stakeholders with a documented current-state view of the environment.

2. Stabilize Legacy Application Operations Throughout the Transition.

Throughout the engagement, maintain reliable operation of the IBM i application while the organization executes its TPA transition, ensuring that required batch processing, reporting, interfaces, data access, and operational functions remain available. Investigate and resolve application-level problems arising from system maintenance, patching, security modifications, infrastructure changes, or undocumented dependencies while coordinating with infrastructure and vendor resources when appropriate.…
