Mainframe Developer

Roles & Responsibilities

• Design, develop, enhance, and support CSF (Custom Statement Formatter) and Documerge templates for high volume batch and on demand customer communications (statements, letters, notices).
• Analyze and modify COBOL programs, copybooks, and JCL that drive document generation, data preparation, and print workflows.
• Perform reverse engineering of legacy CSF / Documerge templates, including RDLs, DDLs, rule bases, VLAM files, and associated COBOL logic to understand layout, rules, and data lineage.
• Map COBOL data structures and copybooks to CSF / Documerge form fields and variables, ensuring accurate population of document content.
• Develop and maintain JCL jobs for document generation, print processing, and downstream distribution (AFP / PDF / print streams).
• Troubleshoot and resolve production issues related to document formatting, missing data, pagination, conditional logic, and batch failures.
• Support testing activities including unit testing, system testing, content comparison, regression testing, and UAT defect resolution.
• Collaborate with business analysts, CSF SMEs, QA teams, and migration teams to clarify requirements and validate document outputs.
• Create and maintain technical documentation covering CSF templates, COBOL logic, JCL flows, data lineage, and business rules to support ongoing maintenance or modernization initiatives.
• Provide input and support for legacy CCM modernization or migration programs (e.g., CSF / Documerge to modern CCM platforms) by extracting rules and specifications.

  • Experience with CSF RDLs, DDLs, rule bases, VLAM libraries, and layout definitions.
  • Familiarity with AFP / PDF generation, print streams, and downstream print or distribution processes.
• Analysis & Testing:
  • Strong skills in reverse engineering legacy CCM solutions to extract layout rules, data mappings, and business logic.
  • Experience supporting content validation, data comparison, and reconciliation between baseline and updated outputs.
  • Able to perform impact analysis across COBOL, JCL, and CSF / Documerge components.
• Domain & Soft Skills:
  • Experience in insurance or financial services environments is highly preferred.
  • Strong analytical and problem solving skills with attention to detail.
  • Ability to work effectively with cross functional teams including business, QA, and architecture groups.
