Job Description

Contract Opportunity: AS400 Developer/Admin (OMES supporting OID) Job Title: AS400 Developer/Admin (Contractor) Location: Oklahoma City, OK (Hybrid options available) Position Type: Contract Contract Duration: 12-Month Initial Assignment (with high probability of extension) Position Overview The Office of Management and Enterprise Services (OMES), in coordination with the Oklahoma Insurance Department (OID), 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, the contractor will focus 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. Key Responsibilities 1. Legacy Application Maintenance & Support Maintain, modify, and optimize custom legacy application code written in RPG, RPG III, RPG IV (ILE RPG), RPGLE, and Control Language (CL). Investigate and troubleshoot operational bugs, batch run anomalies, and user-reported system issues. Update existing logic to adapt to regulatory changes, licensing requirements, and agency business process updates. 2. Application Administration & Infrastructure Liaison Serve as the primary technical point of contact to coordinate with the hosting provider for system maintenance, OS patching schedules, database utilities, and environmental adjustments. Manage application-level security configurations, including user profiles, object-level authority, and verify system audit logs (QAUDJRN) to maintain system integrity. Manage local job queues, active subsystems, and application-level job schedulers. Coordinate with Ensono’s storage and backup operations teams to ensure application backup windows, disaster recovery testing, and restoration verifications are carried out successfully. 3. DB2 Database & Integration Management Query, manage, and tune DB2 for i databases, optimizing SQL queries and indexes to ensure database responsiveness. Support secure, automated file transfers (SFTP/FTP) and interfaces between the hosted AS400 partition and downstream state, regional, or partner systems. 4. Modernization & Migration Enablement Cooperate with state database administrators and cloud architects to extract, clean, and archive legacy tables. Document system flows, database schemas, and interdependencies to facilitate a seamless transition of legacy business logic to modern cloud systems. Required Skills & Qualifications Experience: Minimum of five (5) years of hands-on experience in AS400 (IBM i, iSeries) application development and support. Programming Skills: Exceptional proficiency in RPG IV (ILE RPG), RPGLE, CL, and SQL on DB2 for i. Hosting Coordination: Prior experience working in a hosted/managed AS400 environment, collaborating with external hosting providers (such as Ensono) to resolve infrastructure or environmental issues. Application Administration: Proven experience in IBM i work management, subsystem coordination, application security, and user profile management. Data Integration: Strong background in file transfer automation (FTP, SFTP) and managing external integrations. Highly Valued Skills (Nice-to-Haves): Direct experience assisting in legacy-to-cloud migrations or data warehousing extractions. Familiarity with modern IBM i tools, such as Rational Developer for i (RDi). Prior experience working in public sector environments or supporting insurance regulatory systems. Work Environment and Terms This role is structured as a contract engagement. Candidates must be local to Oklahoma City or willing to relocate , as hybrid schedules require designated on-site days at Oklahoma Insurance Department or OMES facilities. Candidates must pass a comprehensive background check as required by State of Oklahoma IT security standards.
