Mainframe Technology

• Design, develop, and maintain COBOL programs, JCL scripts, and DB2 database components for batch and online mainframe applications.

• Analyze, debug, and resolve production issues in mainframe environments, including file management and scheduling via ESP or similar tools.

• Perform impact analysis for change requests, enhancements, and defect fixes, ensuring minimal disruption to existing processes.

• Optimize performance of COBOL programs, JCL jobs, and DB2 queries to meet SLAs and improve system efficiency.

• Manage and manipulate files using mainframe file management utilities and tools, ensuring data integrity and accuracy across jobs and processes.

• Collaborate with cross-functional teams (BA, QA, operations) to understand requirements, clarify functional specifications, and deliver high-quality solutions.

• Create and maintain technical documentation including program specifications, job flows, data mappings, and operational runbooks.

• Participate in code reviews to ensure adherence to coding standards, best practices, and security/compliance guidelines.

• Support batch scheduling and monitoring using ESP (or equivalent schedulers), including job setup, dependencies, and failure recovery procedures.

• Contribute to testing activities by preparing test data, supporting unit and integration testing, and assisting QA teams in defect analysis.
  Education: Bachelor’s or Master’s degree in Computer Science, Information Technology, or related fields such as BTech, BE, BSc, BCA, MTech, ME, MSc.

• Experience: 3–5 years of hands-on experience as a mainframe developer in an enterprise environment.

• Strong proficiency in COBOL for developing and maintaining batch and online programs.

• Solid experience with JCL for job creation, execution, and troubleshooting in mainframe environments.

• Practical knowledge of DB2 including writing and tuning SQL queries, working with tables, views, and stored procedures on mainframe.

• Proven experience in file management on mainframe platforms, including handling sequential, VSAM, and other common file types.

• Working knowledge of ESP or similar enterprise job scheduling tools for batch job orchestration.

• Ability to analyze requirements and translate them into clear, maintainable technical solutions on mainframe systems.

• Good communication skills to interact effectively with technical and non-technical stakeholders.
