Mainframe Administrators are responsible for installing, configuring, monitoring, and securing mainframe hardware and software. They ensure system performance, troubleshoot technical issues, handle backup and recovery, and apply updates or patches to keep systems running smoothly and securely. This role often requires strong technical skills, attention to detail, and the ability to work with legacy systems.
