Mainframe Developer

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.
