• Diagnose and resolve incidents, problems, and changes while participating in a rotating on‑call schedule.
• Configure parameters, use SMP/E for installation and maintenance, and coordinate with software vendors when needed.
• Monitor supported systems and address issues involving scheduling, tape management, security, and other z/OS tools.
• Contribute to technical projects, assist colleagues with technical questions, and support major‑incident or emergency situations.
• Research and evaluate new supporting software.

Requirements

• At least 7 years of experience in a large‑enterprise mainframe environment, or an equivalent combination of education and experience.
• Bachelor's degree and/or equivalent relevant work experience.
• Strong knowledge of z/OS installation and maintenance, including SMP/E, TSO/ISPF, SDSF, and JCL.
• Strong knowledge of Unix System Services, including USS file‑system management and security.
• Ability to troubleshoot, implement changes, plan work, and remain effective under pressure.
• Strong written and verbal communication, customer service, teamwork, self‑motivation, and learning skills.

Nice to have

• Experience performing moderately complex ISV installations and the core functions of a mainframe systems programmer.
• Knowledge of z/OS security, service structures, Parallel Sysplex, and catalog management.

Benefits and work setup

• Remote work is encouraged when client‑site attendance is not required, with office‑based work also available.
• Flexible scheduling and a wellness program are offered.
• Benefits include paid time off, health‑plan options, a matched 401(k), dental and vision coverage, disability and life insurance, flexible spending accounts, family‑forming support, paid childbearing and parental leave, education or student‑loan assistance, and sabbatical leave.
• The listed full‑time salary range is $85,000–$148,000, with eligibility for annual performance‑based bonuses and an equity grant.
