Mainframe Developer

The State is replacing its aging eligibility platform with a new Eligibility Determination system (EDEN), while the legacy Child Support Enforcement system (ICAR) continues to exchange critical data with it through file-based interfaces and batch processes. The Mainframe Developer will build, test, and support the programs and interfaces that keep both systems working together during the transition., * Develop, enhance, and maintain COBOL and JCL programs that process ICAR-EDEN interface files

• Modify file layouts, data mappings, transformation logic, and validation routines
• Enhance batch workflows, GDGs, and VSAM datasets; support IDMS database applications
• Replace legacy eligibility data sources with EDEN-derived data
• Perform unit testing and support system, integration, regression, and UAT cycles
• Create JCL, PROCs, scheduling definitions, and runbooks; support deployments, cutover, and production issues
• Translate business requirements into technical specifications and collaborate with BAs, testers, and stakeholders

• Strong hands-on COBOL, JCL, and batch processing
• IDMS (schema/subschema, navigation, COBOL integration); ADS/O preferred
• VSAM (DEFINE/REPRO), GDG management, flat file design and parsing
• FTP/SFTP file transfer automation
• Scheduling tools such as CA7 or Control-M
• Legacy system analysis, data mapping, and root cause analysis
• Strong written and verbal communication

Preferred

• Child Support Enforcement, Human Services, or eligibility system experience
• Large-scale legacy modernization or government project experience
• Production support, release management, and Agile/hybrid experience
