The Journeyman Systems Administrator supports full-lifecycle engineering and technical sustainment of the FMWorkFlow (FMWF) system and associated infrastructure. The role performs Windows/Linux administration, Active Directory and service-account engineering, Nutanix virtualization support, configuration-baseline and patch engineering, performance analysis, troubleshooting, backup/recovery support, development/test environment sustainment, and cybersecurity compliance activities in a mission-critical Air Force financial-system environment.

• Administer, configure, maintain, patch, upgrade, monitor, and troubleshoot Windows and Linux systems supporting FMWF infrastructure.
• Perform service-account configuration and Active Directory engineering, including access/account administration consistent with approved security controls and least-privilege principles.
• Support enterprise virtualization engineering using Nutanix, including infrastructure health, capacity, performance, lifecycle sustainment, and troubleshooting.
• Perform infrastructure performance analysis, capacity planning, root-cause engineering, and sustainable corrective actions for performance degradation.
• Manage and maintain approved configuration baselines and support enterprise patch engineering and validation, including IAVAs, TCNOs, NOTAMs, and related directives within prescribed timelines.
• Perform routine lifecycle sustainment and emergency corrective engineering necessary to maintain operational continuity and prevent loss or degradation of mission-critical capability.
• Provide advanced technical escalation support as assigned, including diagnostics, log analysis, troubleshooting, and validation of corrective actions.
• Implement approved system modifications required to maintain usability in evolving technical environments and validate system performance after implementation.
• Support a controlled FMWF development/test environment, including configuration management, patch validation, test-data management, secure backup/off-site storage support, and production-readiness verification.

• Develop and maintain accurate system documentation, procedures, technical records, configuration information, and Section 508-compliant deliverables.

• Windows Server and Linux enterprise administration.
• Active Directory, service accounts, enterprise authentication, system access, and configuration-baseline management.
• Nutanix enterprise virtualization; familiarity with other virtualization platforms may be useful but is not a PWS requirement.
• System monitoring, performance analysis, capacity planning, root-cause troubleshooting, patching, vulnerability remediation, and deployment validation.
• Backup/recovery, resilience, COOP support, and development/test environment operations.
• Scripting/automation using Power Shell, Bash, Python, Ansible, or comparable technologies is beneficial.
