Job description
Structured overview of role & requirements
About This Role
- Lead discovery and reverse engineering of mainframe portfolios across source code, online transactions, batch, data, and integrations; document business rules, workflows, architecture, and dependencies.
- Assess modernization readiness, technical debt, complexity, and operational risk to inform transformation planning and target-state design.
- Validate AI-assisted discovery findings and provide hands-on SME support for production troubleshooting, migration testing, parallel runs, and cutover.
Minimum Requirements
- Work Experience Required: 10+ years of hands-on mainframe application development, support, or architecture experience.
- Bachelor’s degree in Computer Science, Information Systems, Engineering, or a related discipline.
- Deep expertise in COBOL-based enterprise applications and mainframe online, batch, database, and messaging architectures; required technologies include COBOL, PL/I, Assembler, JCL, CICS, IMS, DB2, VSAM, and IBM MQ.
- Proven experience in legacy source-code and dependency analysis, production troubleshooting, batch analysis, and documenting application behavior and architecture, including systems with limited existing documentation.
Ideal Candidate Profile
- Has led mainframe discovery or modernization assessments, including dependency mapping, batch-chain or transaction-flow tracing, and migration-readiness evaluation.
- Can connect legacy application behavior to cloud-native or distributed target capabilities and support functional-parity validation during migration.
- Has experience with AI-assisted discovery or code-analysis tools, KAF output validation, and large-scale modernization programs; regulated-industry experience is a plus.
