Senior SME / Solution Architect – CA VISION to COBOL Migration
 
Role: Senior SME / Solution Architect
Engagement: CA VISION / VISION to COBOL Migration
 
Job Description
  • We are seeking a Senior SME / Solution Architect with strong CA VISION and IBM z/OS mainframe expertise to lead the analysis, architecture, and migration of legacy CA VISION applications to COBOL.
  • The consultant will understand complex VISION programs, business rules, data flows, reports, and interfaces and translate them into maintainable, production-ready COBOL solutions while preserving existing business functionality.
Key Responsibilities
  • Expert-level CA VISION / VISION experience.
  • Strong hands-on COBOL, JCL, VSAM, DB2, and z/OS experience.
  • Strong REXX scripting experience for z/OS/ISPF automation and mainframe tooling.
  • Strong Python experience for migration automation, source-code parsing, transformation, validation, reporting, and data analysis.
  • Deep understanding of legacy mainframe application architecture and modernization.
  • Experience with CICS, SORT/DFSORT, IDCAMS, ISPF, SDSF, and standard z/OS utilities.
  • Lead end-to-end CA VISION / VISION application assessment and migration to COBOL.
  • Analyze VISION source code, including VISION verbs, macros, report definitions, file processing, calculations, sorting, formatting, and business rules.
  • Reverse-engineer undocumented legacy VISION applications and create functional and technical specifications.
  • Design target COBOL architecture, including batch processing, VSAM/DB2 access, reporting, error handling, restart/recovery, and operational processing.
  • Map VISION constructs and verbs to COBOL, JCL, DFSORT/SORT, DB2, VSAM, and z/OS utilities.
  • Develop reusable VISION-to-COBOL conversion standards, mappings, patterns, and coding guidelines.
  • Review migrated COBOL programs and provide technical direction, architecture guidance, and code-quality assurance.
  • Design and validate JCL, compile/link-edit processes, datasets, scheduling, and production implementation procedures.
  • Ensure migrated applications integrate appropriately with existing CICS, DB2, VSAM, and other z/OS services, where applicable.
  • Develop migration automation and productivity tools using REXX and Python for source analysis, code transformation, validation, comparison, reporting, and migration tracking.
  • Define and execute unit, system, integration, regression, and parallel-run testing to establish functional equivalence between VISION and COBOL.
  • Perform application impact analysis, dependency analysis, performance analysis, and production troubleshooting.
  • Work with business SMEs, application teams, QA, infrastructure, and offshore development teams.
  • Provide onshore technical leadership and serve as the primary CA VISION migration SME.
  • Produce architecture documents, conversion specifications, migration plans, estimates, technical standards, risk assessments, and implementation documentation.
Required Technical Skills
  • Ability to analyze undocumented legacy applications and reconstruct complex business logic.
  • Experience developing VISION-to-COBOL conversion/migration frameworks and standards.
  • Strong knowledge of batch processing, datasets, scheduling, restart/recovery, and production support.
  • Strong experience with source-code analysis, impact analysis, testing, and migration validation.
Preferred Skills
  • Experience with CA VISION, VISION, or related VISION products.
  • Experience leading large-scale legacy modernization/conversion programs.
  • Experience developing automation frameworks using Python + REXX.
  • Familiarity with automated code-conversion, parsing, and static-analysis tools.
  • Experience leading distributed onshore/offshore technical teams.
  • Excellent communication, technical documentation, and stakeholder-management skills.
Experience
  • 12+ years of overall mainframe experience, with significant hands-on experience in CA VISION, COBOL, REXX, and z/OS, including demonstrated leadership of complex legacy modernization or migration initiatives.
