Original job description

Job Title: Information Security Systems Engineer (Linux/Windows Systems Administrator) 5

Job Code: 46907

Job Location: Waco, TX

Job Schedule: 9/80: Employees work 9 out of every 14 days- totaling 80 hours worked- and have every other Friday of

Job Description:

The Information Security Systems Engineer 5 (Linux/Windows Systems Administrator) serves as the dedicated systems administrator for Waco's secure, isolated lab and air-gap environments. The role provides on-site ownership for the Linux and Windows infrastructure that supports multiple US Government Programs, engineering, and related mission work. The administrator provisions, secures, operates, troubleshoots, and documents systems and services while maintaining clear boundaries among Secure Area IT, Program teams, and Industrial Security.

Essential Functions:

Administer Red Hat-based Linux servers and workstations and Windows Server and workstations, including provisioning, troubleshooting, patching, privilege management, identity and access administration, configuration changes, and lifecycle support across secure lab and isolated network environments.
Build and maintain infrastructure services such as DNS, DHCP, NFS, automounts, SMB/Samba, Windows domain services, Active Directory, FreeIPA or LDAP, NTP, virtualization, storage, backup, and monitoring. Keep these services documented and recoverable so the air-gap environment can support users and engineering teams without relying on remote enterprise access.
Support software engineers with secure development infrastructure, including controlled remote access, standardized workstation and server images, source-code and DevOps platforms, and practical troubleshooting of multi-operating-system environments. Translate engineering needs into supportable services and clear ownership boundaries.
Partner with information security stakeholders to harden and audit systems to security guidance. Implement or sustain STIG baselines, patching, vulnerability remediation, endpoint protection, centralized logging, security-tool integration, and evidence needed for CMMC, ATO, continuous monitoring, and Program accreditation activities.
Maintain operational evidence and status reporting, including asset and service inventories, ownership records, network and configuration diagrams, standard operating procedures, change records, audit artifacts, and clear reporting of open gaps, owners, aging, and next actions.
Provide on-site operational response for incidents, outages, recovery activities, vendor coordination, emergency coverage, and closeout actions. Help stabilize a dependable local support model for the Waco secure-area environment and keep the program moving from partial operation toward an accredited sustainment model.

Qualifications:

Bachelor’s Degree in Computer Science, Information Technology, or a related field and minimum 9 years of prior relevant experience. Graduate Degree in Computer Science, Information Technology, or a related field and a minimum of 7 years of prior related experience. In lieu of a degree, minimum of 13 years of prior related experience in systems administration.
Hands-on experience with Linux administration on Red Hat-based distributions, Windows administration, Active Directory, shell scripting, network and storage services, system hardening, and support for secure environments.

Preferred Additional Skills:

Experience with configuration management and automation tools such as Ansible, AWX, Puppet, or Chef; centralized authentication technologies such as Active Directory, FreeIPA, LDAP, Kerberos, or IDM; and source code platform administration using GitLab, GitHub, or SVN.
Security+ or equivalent security certification is strongly desired; experience with STIG implementation, audit readiness, Windows domain operations, and cross-functional support in defense or regulated environments is highly valuable.
Familiarity with CI/CD pipelines, DevOps platforms, log analysis, metrics and monitoring, virtualization, multi-operating-system environments, cloud platforms, and security-focused troubleshooting in distributed systems.
