What Does a Mainframe Developer Do?

Mainframe Developers are specialized software developers who primarily work with mainframe systems used by large organizations for critical applications, typically bulk data processing such as census, industry and consumer statistics, and financial transaction processing.

They are responsible for designing, coding, testing, and debugging applications and software on mainframe systems.

They often use programming languages such as COBOL, CICS, JCL, and DB2 for development.

Mainframe Developers work collaboratively with other IT professionals, including system analysts and project managers, to understand the requirements and specifications for new applications or modifications to existing ones.

They then translate these requirements into detailed program designs, write the code, and perform testing to ensure the applications function as expected.

In addition to development work, Mainframe Developers may also be responsible for system maintenance, which includes troubleshooting and fixing bugs, performance tuning, and upgrading system software.

They also document their work and sometimes provide technical support and training to end users.

As technology evolves, Mainframe Developers may also be involved in migrating legacy systems to newer platforms and technologies.

This could involve reengineering the existing mainframe applications or integrating them with other systems.

 

Mainframe Developer Qualifications and Skills

Mainframe Developers require a unique combination of technical skills, analytical abilities, and industry knowledge to create, maintain and test software applications within a mainframe environment.
