Summary/Objective

Five Stones Research Corporation (5SRC) is seeking energetic candidates to join our established and growing Huntsville-headquartered team.

Essential Functions

Endpoint Lifecycle Management & MECM/SCCM Administration

Serve as the primary administrator for Microsoft Endpoint Configuration Manager (MECM / SCCM), managing infrastructure health, site systems, distribution points, and client agent health across all connected enclaves.
Engineer, test, deploy, and maintain standardized Windows Operating System Deployment (OSD) task sequences and baseline golden images.
Package, test, distribute, and automate application installations, scripts, and software updates across heterogeneous lab and hosting workstations and servers.
Manage and orchestrate enterprise-wide software update distribution using Software Update Points (SUP) integrated with Windows Server Update Services (WSUS).
Create and deploy custom compliance baselines and configuration items (CIs) to enforce security settings, STIG configurations, registry keys, and audit controls.
Develop custom MECM queries, device collections, and reports (SSRS) to provide real-time hardware/software inventory, asset discovery, and compliance auditing.

Systems Administration (Linux & Windows)

Administer, build, configure, and maintain physical and virtual Red Hat Enterprise Linux (RHEL) servers, modern Windows Servers (2019/2022), and Windows 10/11 workstations.
Manage core directory and identity infrastructure, including Active Directory Domain Services (AD DS), Group Policy Objects (GPOs), DNS, DHCP, and role-based access control.
Troubleshoot and maintain enterprise Linux services, including SE Linux policies/security contexts, daemon services (systemd, chronyd), file systems (/opt, logical volumes), and local package managers.
Maintain hypervisor and storage infrastructure, including Nutanix, VMware ESXi/vCenter, and enterprise backup/restore solutions (e.g., Cohesity, snapshots).
Support basic multi-tier database hosting and connectivity for Oracle and Microsoft SQL server backends.
Process, approve, and maintain user access documentation and account provisioning via DD Form 2875 and identity management systems.
Issue, configure, and troubleshoot Public Key Infrastructure (PKI) certificates, CAC authentication, and secure remote protocols across all client and server endpoints.

Cybersecurity, Vulnerability Management & Compliance

Maintain strict system security posture in compliance with Defense Information Systems Agency (DISA) Security Technical Implementation Guides (STIGs) and Security Requirements Guides (SRGs).
Execute, review, and analyze weekly Assured Compliance Assessment Solution (ACAS / Tenable Nessus) vulnerability scans and monthly STIG evaluations.
Rapidly remediate identified CVEs, IAVM alerts, CTO/DTO directives, and vendor patches across both Windows and Linux fleets.
Draft, track, and update Plans of Action and Milestones (POA&Ms) for items requiring architectural mitigations or extended test schedules.
Maintain endpoint security agents across all hosts, including Trellix/ePO agents, endpoint detection and response (EDR), and application whitelisting tools (e.g., fapolicyd).
Monitor and analyze system, security, and application logs using SIEM and centralized log management tools (e.g., LogRhythm, Elastic Fleet).

Required Qualifications:

One of the following combinations of education and experience:
Requires a Master’s degree
Bachelor’s degree with at least 4 years of experience
Associate’s and at least 6 years of experience.
One year of experience can be substituted by 15 semester hours completed towards a Master’s degree. Additional certifications (other than those required for the position) in the area of specialization be substituted for experience but varies by certification. The degree must be in a relevant technical curriculum and experience must be related to the job duties.
Minimum of 3–5+ years of hands-on systems administration experience across mixed Linux (RHEL) and Windows enterprise server/workstation environments.
Minimum of 2+ years of dedicated, hands-on administration of Microsoft Endpoint Configuration Manager (MECM / SCCM) in an enterprise or lab environment.
Active DoD 8570/8140 IAT Level II Baseline Certification (e.g., CompTIA Security+ CE, CCNA Security, CySA+, GICSP, GSEC, or SSCP).
Relevant computing environment (CE) / vendor training or certification in Microsoft Windows Server/MECM or Red Hat Enterprise Linux (or ability to complete within 6 months of hire).

Preferred Qualifications:

Demonstrable proficiency configuring, operating, and troubleshooting MECM/SCCM (OSD, application packaging, software update deployments, collection management).
Strong working knowledge of Linux administration, specifically Red Hat Enterprise Linux (RHEL), CLI troubleshooting, package management, daemon tuning, and SELinux enforcement.
Solid experience with Windows Server (2019/2022) administration, Active Directory, GPO authoring/troubleshooting, and DNS.
Experience with DoD vulnerability and compliance tooling: ACAS (Tenable/Nessus), SCAP Compliance Checker (SCC), and STIG Viewer (.ckl generation).
Understanding of enterprise backup technologies, bare-metal server recovery, and hypervisor virtualization (Nutanix AHV, VMware).
Excellent written communication skills for authoring Standard Operating Procedures (SOPs), weekly status reports, and technical troubleshooting documentation.
Prior experience administering systems within DoD enterprise testing facilities, operational lab environments, or defense staging enclaves.
Proficiency with PowerShell scripting and Linux Shell (Bash) scripting to automate routine administration, reporting, and deployment tasks.
Hands-on experience managing and troubleshooting enterprise backup appliances (e.g., Cohesity) and application whitelisting tools (e.g., fapolicyd).
Familiarity with Elastic Agent/Fleet management, LogRhythm, or enterprise SIEM architectures.
Basic understanding of perimeter network components (firewalls, VPNs, F5 BIG-IP load balancers) and cloud hosting environments (AWS GovCloud).
