  • Coordinate with COBOL, CICS, DB2, Assembly Language Coding, database, and infrastructure specialists to resolve interoperability and integration problems between Java and legacy mainframe applications.
  • Investigate mainframe interface failures, batch-processing problems, data-transfer issues, job abends, database errors, and production defects affecting Java applications.
  • Support Final Integration Testing readiness, defect investigation, code corrections, production implementation, and post-deployment monitoring for Java and mainframe-integrated applications.
  • Integrate applications with IRS enterprise systems, shared services, databases, infrastructure, and external interfaces.
  • Develop and maintain solutions using Oracle, PL/SQL, DB2, XML, HTML, and related technologies.
