Job Title: AS400 Developer/Admin (Contractor)
Location: Oklahoma City, OK (Hybrid options available)
Position Type: Contract
Hours: 20 hours per week
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.
