Space Dynamics Laboratory•North Logan, UT

18h•Onsite

About The Position

Space Dynamics Laboratory (SDL) is seeking two Linux Systems Administrators to support the implementation and ongoing management of Linux systems across both servers and endpoints within a Microsoft Azure Government (GCC High) environment. These roles will focus on building secure, standardized Linux configurations and maintaining compliance across a hybrid cloud footprint. This work includes deploying hardened Linux images, enforcing STIG baselines, integrating identity and access controls, and ensuring visibility through centralized logging and endpoint protection. These roles will support both infrastructure services and user-facing Linux endpoints, with a strong emphasis on security and compliance aligned to CMMC requirements. This position is on-site in North Logan, UT, and requires close collaboration with cloud, cybersecurity, and infrastructure teams.

Requirements

5+ years of experience administering Linux systems (RHEL, Ubuntu, or similar) across servers and/or endpoints
Experience with disk encryption (LUKS) and secure communication protocols (TLS)
Strong understanding of Linux authentication (PAM) and enterprise identity integration with MFA
Experience with EDR tools on Linux (Microsoft Defender preferred)
Experience configuring centralized logging (Rsyslog, SIEM integration such as Sentinel)
Experience managing patching and software distribution across multiple Linux systems
Familiarity with Azure, Azure Government, or hybrid cloud environments
Must be a U.S. citizen
Must be able to obtain and maintain a DoD security clearance
Must be able to travel as needed (not a normal expectation)
Valid CompTIA Security+ certification (or equivalent) is required or must be obtained within 30 days of hire

Nice To Haves

Experience with Azure Arc, Foreman, or Red Hat Satellite for managing Linux servers and endpoints
Experience automating configuration and compliance (Ansible, Bash, or similar)
Familiarity with Microsoft Sentinel and KQL for log analysis
Experience with PKI solutions such as Sectigo for certificate management
Background supporting CMMC, NIST 800-53, or similar compliance frameworks
Experience in hybrid environments, integrating on-prem infrastructure with Azure
Prior experience supporting Linux endpoints in enterprise Azure GCC High environments
Hands-on experience implementing STIGs and validating compliance using SCAP

Responsibilities

Implement and maintain hardened Linux systems (RHEL/Ubuntu) across servers and endpoints in Azure Government and on-premises
Configure and enforce encryption at rest (LUKS) and in transit (TLS/PKI infrastructure)
Support secure email encryption integrations (S/MIME with Sectigo or equivalent)
Integrate Linux systems with enterprise identity systems (IDAM) with MFA in both online and offline scenarios
Configure and manage PAM policies for authentication and privileged access
Deploy and maintain EDR solutions (e.g., Microsoft Defender for Endpoint for Linux)
Implement centralized logging using Rsyslog and forward logs to Microsoft Sentinel
Manage patching, updates, and software lifecycle across Linux servers and endpoints
Establish and maintain secure connectivity between on-prem and Azure resources
Support audit readiness and continuous monitoring for compliance frameworks (CMMC)
Troubleshoot system, security, and integration issues across hybrid environments
