Job ID: JOB_ID_6468
Role Definition:
The Mainframe Legacy Modernization Engineer will play a key role in transforming large, complex mainframe applications into modern, scalable, and cloud-ready architectures. The engineer will work across assessment, reverse engineering, migration, refactoring, and rearchitecture initiatives, collaborating with architects, business SMEs, and cloud teams to modernize COBOL-based systems into microservices, APIs, and distributed platforms. This role requires strong hands-on mainframe expertise combined with modern application, integration, data transformation, and cloud engineering skills.
Key Responsibilities:
- Analyze complex mainframe applications (COBOL, CICS, JCL, DB2, VSAM, MQ) to understand business rules, data flows, batch cycles, and system interdependencies.
- Perform inventory analysis, call chain analysis, and functional decomposition of monolithic applications.
- Extract and document technical and business rules using automated discovery or reverse engineering tools.
- Design and implement modernization strategies including rehost, replatform, refactor, rearchitect, replace, or retire approaches.
- Convert or refactor legacy COBOL logic into modern languages such as Java using automated tools or manual reengineering techniques.
- Apply incremental modernization patterns such as strangler fig and coexistence models to reduce migration risk.
- Modernize JCL-based batch processes into cloud-native batch frameworks (e.g., Spring Batch, workflow orchestration).
- Support migration or reengineering of scheduling, file transfer, and output management components.
- Ensure functional parity and data integrity between legacy and modernized systems.
Required Skills & Experience:
- 8-10 years of overall IT experience with a strong focus on mainframe application development and modernization.
- Experience with API design, REST services, and integration middleware.
- Knowledge of modernization patterns such as rehost, replatform, rewrite, and strangler fig approaches.
