Why we read it this way (7)
The role is classified as 15-1244 (Network and Computer Systems Administrators) because its primary day-to-day work is operating, administering, and maintaining mainframe infrastructure (z/OS, storage, GDPS, replication) rather than building new software. However, 15-1252 (Software Developers) is noted as a runner-up given the JCL/REXX scripting and some programming language in the experience requirement.
The experience requirement has two paths: a Bachelor's degree plus 6 years, or a High School Diploma/GED plus 10 years. The overall years minimum is set to 6 (the lower gate with a degree). Neither path hard-requires a specific degree, so the degree requirement is set to None.
The compensation figures ($102,691.05 minimum, $133,000.00 median) are described as an MSA Market Range, not a traditional min/max salary band. The median is used as the max figure here for reference.
The position is listed as 'offsite' (primarily work-from-home) but preferably near a Regions office; remote is set to true accordingly.
The mainframe product list in the Requirements section (ZOS, CICS, MQ, DB2, Storage, Automation, ZLINUX, Networking) is presented as an 'including … or' list of examples, but all are treated as hard gates given their placement in the Requirements block.
Skills listed under the 'Preferred' and 'Preferred Qualifications' headings — JCL, REXX, TSO/ISPF, SMP/E, Parallel Sysplex, Coupling Facility — are marked as preferred. The detailed storage and GDPS responsibilities in the Skills and Competencies section are treated as required given their placement alongside firm requirements language.
The posting states Regions will not sponsor work visas for this position.
