As the Agile Center of Excellence for the Program Executive Office Enterprise (PEO Enterprise), the U.S. Army Product Lead Acquisition, Logistics, and Technology Enterprise Systems and Services (PL ALTESS) runs enterprise-class data centers that host hundreds of programs, thousands of virtual servers, and millions of users worldwide, 24x7x365. Our team delivers the full spectrum of IT services: data center and Service Operations Center operations, network and systems administration, cybersecurity, cloud and application modernization, disaster recovery, and lifecycle testing across physical, virtual, and cloud architectures spanning multiple geographic locations.

Manage, maintain, deploy, troubleshoot, and support RHEL/Oracle Linux and Solaris servers across a mixed customer environment.
Plan, execute, and implement new system hardware and software, and lead new HW/SW integrations.
Monitor and tune system performance, and keep day-to-day server operations running smoothly.
Harden servers (STIG, SELinux, firewalld) and report on overall security and operational status.
Produce utilization reports with existing tools to identify problems and drive corrective actions.
Manage the lifecycle of multi-vendor data center equipment, including firmware version control and periodic preventive maintenance.
Create and maintain team technical instructions, operating procedures, and policies.
Recommend, demonstrate, and implement technologies that expand, upgrade, and increase efficiency in the environment.

US Citizenship
3+ years as a UNIX/Linux Systems Administrator or IT Engineer, including automating assigned tasks.
3+ years of patch management experience, including applying security updates with DNF/YUM and RPM.

3+ years managing a large pool of local users from the command line.
3+ years creating, maintaining, and following SOPs for repeatable processes, disaster recovery, and common problem resolution.
3+ years configuring and maintaining key services such as DNS, SFTP, SMTP, and NTP.
Strong interpersonal skills and a team-player mindset.

WHAT SETS YOU APART (DESIRED)

3+ years of basic and advanced SELinux management and configuration.
Experience supporting cybersecurity patch management, STIGs, SRGs, RMF, SCA-V, and Cyber Operational Readiness Assessments (CORA).
