  • Troubleshoot batch failures, abends, data discrepancies, and performance issues related to migration processing.
  • Collaborate with database administrators, architects, business analysts, and project teams to define migration requirements and resolve technical challenges.
  • Create technical documentation, migration runbooks, implementation procedures, and production support documentation.
  • Participate in migration testing, system integration testing, user acceptance testing, and production implementation activities.
  • Provide production support during migration cutover and post-implementation stabilization periods.
  • Identify opportunities for automation using CLIST, REXX, File-AID, and other mainframe utilities.
  • Ensure compliance with enterprise change management, security, and audit requirements.
Qualifications
  • 10+ years of Mainframe Development experience.
  • Expert-level COBOL programming experience.
  • Strong JCL development and troubleshooting skills.
  • Extensive IMS Database experience.
  • Experience with BMC Utilities for IMS.
  • Experience developing large-scale data extracts and conversion processes.
  • Strong understanding of FTP/SFTP file transfer methodologies.
  • Proven experience supporting enterprise data migration or modernization initiatives.
  • Experience performing data analysis, reconciliation, and validation.
  • Ability to work independently with minimal supervision in a deadline-driven environment.
Preferred Qualifications
  • Experience with File-AID.
  • Experience with EZtrieve.
  • Experience with CLIST and REXX automation.
  • Prior experience with legacy modernization or cloud migration projects.
  • Experience supporting financial services, insurance, healthcare, or government mainframe environments.
Critical Success Factors
