SME / Solution Architect

Role: Senior SME / Solution Architect Engagement: CA VISION / VISION to COBOL Migration, * 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.

• 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.
