• Hands-on experience with SMP/E, APAR creation, and maintenance workflows

• Proficiency in JCL and REXX scripting

• Experience with dump analysis and debugging tools such as IPCS

• Solid understanding of mainframe security models (RACF, Top Secret, ACF2)

• Ability to troubleshoot complex distributed and mainframe-integrated systems

• Strong analytical and problem-solving skills

What You'll Bring

• Experience with C and C++ is a strong plus

• Exposure to mainframe assembly language (ability to read and understand required; deep expertise is a plus)

• Experience with CICS and IMS integration

• Familiarity with database connectivity systems or the Teradata ecosystem

• Experience working in hybrid environments involving mainframe and cloud systems
