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.

Coordination: Prior
experience working in a hosted/managed AS400 environment, collaborating with
external hosting providers (such as Ensono) to resolve infrastructure or
environmental issues.

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.
