AIX ADMINISTRATOR JOB DESCRIPTION

Unpatched firmware, a failed LPAR, and an unscheduled 3 a.m. outage: that is what happens when no one owns this seat. AIX Administrators hold primary accountability for IBM Power Systems availability within enterprise and managed service environments, where uptime SLAs govern how clients measure vendor performance. The role spans hands-on server administration, HACMP cluster management, and capacity planning across PowerVM-virtualized infrastructure. Deep enough to resolve a VIO configuration conflict, broad enough to advise on storage architecture.

As the AIX Administrator, you maintain the stability, security, and performance of IBM AIX and Unix server environments that enterprise operations depend on to meet client SLA commitments. You work within a platform or infrastructure team, coordinating with application, database, and project stakeholders from build through go-live and into steady-state support.

Career Impact: Hands-on ownership of IBM pSeries platforms and POWERHA clustering builds a specialization that commands senior infrastructure and architect-level roles in enterprise IT.

Business Impact: When AIX environments stay available and patched, client SLA targets are met and the revenue tied to managed service contracts is protected.

Growth Opportunity: Experience across PowerVM virtualization, SAN integration, and automation scripting positions you to move into Lead or Architect roles overseeing multi-platform infrastructure roadmaps.

• Install, configure, and maintain AIX server environments across Power7, Power8, and Power9 frames to meet agreed availability standards.
• Manage HACMP cluster configuration and VIO server operations to sustain high availability across production workloads.

• Experience with configuration management or automation platforms applied to OS patching and server provisioning workflows.
• Familiarity with IT security frameworks including vulnerability assessment methodology and compliance-driven patching cycles.
• Exposure to project-based server delivery, including build sheet execution and handover to production support teams.

• System uptime percentage against client SLA targets, measured across managed AIX server inventory.
• Mean time to resolution for P1 and P2 incidents affecting AIX or PowerVM environments.
• Patch currency rate, measured as the percentage of servers current within the approved TL release window.
• Number of manual operational tasks converted to automated scripts per quarter, reflecting efficiency improvement.
• Change success rate, measured as the percentage of approved changes completed without unplanned rollback.
• Typical tools: IBM HMC (hardware management), AIX NIM (network installation management), shell scripting environments (commonly Bash or Perl), automation platforms (commonly Ansible).

• Base Salary Range: $90,000 to $130,000 per year depending on seniority and location.
• Bonus: Annual performance bonus of 5% to 10% of base salary.
