Mainframes Developer information

Are mainframe engineers in demand?

Mainframes developers are in steady demand due to the continued use of mainframe systems in industries like finance, government, and healthcare. They require specialized skills in COBOL, JCL, and mainframe environments, and demand often depends on the organization's reliance on legacy systems. While some companies are transitioning to newer technologies, mainframe expertise remains valuable for maintaining critical infrastructure.

What is mainframe developer salary?
