Why we read it this way (8)
The role is firmly 15-1244 (Network and Computer Systems Administrators): the primary day-to-day work is administering, configuring, maintaining, and troubleshooting existing mainframe network infrastructure (z/OS Communications Server, VTAM, TCP/IP, GDPS, TPX, Connect:Direct) — operating systems others built, not shipping new software.
The job title carries no seniority level; 'Unspecified' is used for advertised seniority. The 7-year experience gate and the scope of responsibilities (multi-datacenter DR, on-call rotation, enterprise-wide mainframe networking) support a Senior classification.
The minimum education requirement is an Associate's degree OR equivalent work experience, so no formal degree is hard-gated.
The pay range ($119,765–$140,900) is stated as reflecting the primary location; U.S. Bank's headquarters is in Minneapolis, MN, used as the CBSA. The posting notes the actual range may differ by location.
All skills listed under 'Basic Qualifications' and the responsibilities section are marked required. Skills appearing only under 'Preferred Skills/Experience' (Enterprise Extender, SSL/TLS, DNS, network monitoring tools, disaster recovery processes) are marked preferred.
FTP is mentioned in the responsibilities but is a generic protocol subsumed by the more specific SFTP/FTPS/FTP-AT/TLS entries; it is not emitted as a separate skill to avoid redundancy.
The alt SOC (15-1252) is noted only as a distant runner-up; the role has no meaningful software development component.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): IBM z/OS Communications Server.
