A Mainframe Applications Developer is an IT professional who designs, develops, and maintains software applications that run on mainframe computers. Mainframes are powerful computing systems used by large organizations for critical applications, such as banking, insurance, and government systems. These developers typically work with programming languages like COBOL, JCL, and CICS, and ensure that mainframe applications are efficient, secure, and reliable. Their responsibilities also include troubleshooting issues, optimizing performance, and supporting system integration with modern technologies.

How does a Mainframe Applications Developer typically collaborate with business analysts and other IT teams during a project?

Mainframe Applications Developers regularly work with business analysts to clarify requirements, translate business needs into technical specifications, and ensure that solutions meet organizational objectives. They often participate in cross-functional meetings with infrastructure, quality assurance, and operations teams to coordinate deployments, troubleshoot issues, and optimize performance. Effective communication and collaboration are essential, as developers must align their code with broader system architectures and adhere to change management processes. This teamwork ensures smooth project delivery and ongoing system reliability.

Job Description

We are seeking an experienced Mainframe Developer with strong expertise in DevOps Migration to support modernization initiatives for enterprise mainframe environments. The ideal candidate will have hands-on experience in legacy application development, z/OS support, CI/CD enablement, and migration planning/execution within large-scale enterprise environments.

KEY RESPONSIBILITIES

Mainframe Development & Support

  • Design, develop, and maintain mainframe applications using COBOL, PL/I, JCL, REXX, and Assembler.
  • Analyze existing legacy programs and batch jobs to assess modernization readiness and reusability.
  • Develop and optimize DB2 for z/OS queries, stored procedures, and data access logic.
  • Support CICS and IMS transaction processing applications throughout the development lifecycle.
  • Troubleshoot and resolve production incidents, abends, and performance issues in z/OS environments.

DevOps & CI/CD Enablement

  • Implement and manage CI/CD pipelines for mainframe application delivery using IBM Dependency Based Build (DBB), Jenkins, Tekton, or equivalent tooling.
  • Migrate mainframe source code to Git-based version control (GitHub, GitLab, Bitbucket) and establish branching and release strategies.
  • Develop automated unit and regression test frameworks for COBOL/PL/I programs using tools such as IBM Rational Test RealTime or IBM Z Open Testing.
  • Define and enforce DevOps standards, code review practices, and deployment governance for mainframe delivery teams.
  • Integrate mainframe build and deploy processes with enterprise DevOps platforms (Jira, Confluence, ServiceNow).

Migration Planning & Execution

  • Conduct discovery and impact analysis of z/OS workloads — JCL, batch jobs, datasets, and application interdependencies — to support migration planning.
  • Prepare detailed migration plans, task breakdowns, and effort estimates for management and stakeholder review.
  • Execute controlled migrations between environments (Dev, Test, Production) ensuring data integrity and minimal downtime.
  • Manage cross-LPAR dataset transfers, SMP/E activities, and library migrations using approved methods (FTP, XMIT, IDCAMS).
  • Document pre- and post-migration states, cutover procedures, and rollback plans.

Collaboration & Stakeholder Engagement

  • Work closely with infrastructure teams on LPAR configuration, storage, and system software upgrades (e.g., DB2 version upgrades, IBM software installs).
  • Coordinate with application owners, QA teams, and project managers to align delivery timelines and resolve technical dependencies.
  • Contribute to DevOps capability-building by coaching junior developers and conducting internal knowledge-transfer sessions.
  • Prepare technical documentation, runbooks, and status reports for internal and client audiences.
