Application Developer

Position Summary

LCI is seeking an experienced, high-caliber AS400 Developer/Admin for a long-term contract engagement. This critical resource will provide essential application maintenance, database management, and application-level administration services for OID’s core IBM AS/400 (IBM i Series) environment. Because the underlying AS/400 hardware partition, operating system, and baseline infrastructure are fully hosted and managed by an external provider, this position does not require hardware or OS-level systems engineering.

Instead focus will be on application development, software support, database management, and serving as the technical liaison to Ensono for environment-level modifications. Additionally, the contractor will play a key role in assisting state IT leadership with database extraction, documentation of legacy business logic, and support for ongoing cloud migration and data archiving initiatives.
