Proficiency with ISPF/PDF, SDSF, and RACF or equivalent security tools.
Working knowledge of source control and change management tools such as Endevor, ChangeMan, or SCLM.
Familiarity with MQ Series (IBM MQ) for message queuing and integration with distributed systems.
Experience with TSO/ISPF environments and z/OS system utilities.
Understanding of Mainframe performance monitoring tools (e.g., IBM Omegamon, CA Mainview, or equivalent).

Preferred / Nice-to-Have Skills

Experience with PL/I, Assembler, or REXX scripting is a strong plus.
