Linux/AIX Engineer

Job#: 3026313

Job Description:
Senior AIX / Linux Engineer - Onsite | Contract-to-Hire

A major technology services provider supporting a large, county-wide enterprise environment is seeking a Senior AIX / Linux Engineer for a long-term contract-to-hire opportunity. This role is a critical backfill for a senior AIX engineer who was foundational to ongoing platform modernization and ERP-related infrastructure.

This is a highly stable, mature environment with long-standing program continuity, strong operational discipline, and multi-year funding already secured. Engineers who enjoy deep system ownership, hands-on troubleshooting, and supporting core enterprise platforms will thrive in this role.
Role Overview

This position is AIX-centric, with responsibility for administering and supporting IBM AIX environments that underpin mission-critical enterprise and ERP platforms. While the broader environment includes Red Hat Enterprise Linux, AIX expertise is the primary requirement for this role.

The ideal candidate is a true "in-the-trenches" engineer-someone comfortable owning complex systems end-to-end, troubleshooting production issues, and maintaining highly available enterprise infrastructure.
Work Model & Location

• Onsite in Santa Ana, CA
• Standard business hours with occasional after-hours maintenance
• 6-month contract-to-hire
• Long-term program stability with multi-year contract extension already in place

Key Responsibilities

• Administer, support, and maintain enterprise IBM AIX environments
• Manage LPARs, VIOS, storage integrations, patching, and lifecycle management
• Perform system hardening, compliance activities, and monthly patching
• Troubleshoot complex OS-level, performance, and infrastructure issues
• Support ERP-related infrastructure and other mission-critical enterprise platforms
• Integrate and manage privileged access and security controls
• Automate operational tasks using Ansible or similar tools
• Collaborate closely with network, storage, virtualization, and application teams
• Participate in on-call rotations supporting high-availability environments
• Contribute to documentation, runbooks, and operational standards
• Provide Linux (RHEL) support where applicable as part of the broader environment

Required Qualifications

• 3+ years of hands-on AIX administration experience in large enterprise environments. Recent experience preferred.
• Strong experience with:
  • LPAR and VIOS management
  • AIX patching, upgrades, and lifecycle management
  • Performance tuning and deep system troubleshooting
• Proven ability to support mission-critical production systems
• Experience with privileged access tools and security integrations
• Hands-on operational automation experience (Ansible or similar)
• Comfortable operating as a hands-on, execution-focused engineer
• Strong communication skills and ability to work in a collaborative team environment
• Must have lived in the U.S. for 10+ years (background requirement)

Preferred Qualifications

• Experience supporting ERP platforms or large enterprise application environments
• Strong Red Hat Enterprise Linux (RHEL) experience
• Familiarity with VMware or enterprise virtualization platforms
• Experience with monitoring, logging, and configuration management tools
• Scripting experience (Bash, Python, or similar)
