Systems Administrator (Linux)

Linux Systems Administration (Primary Focus)

• Install, configure, maintain, and secure Linux systems in accordance with NIST 800-171 controls.
• Perform routine patching, updates, vulnerability remediation, and configuration management.
• Manage Linux-based services (systemd, Nginx/Apache, SSH, syslog).
• Configure filesystems, storage, permissions, encryption, and backups in compliance with security requirements.
• Develop and maintain automation scripts (Bash, Python) to improve consistency and compliance.

Windows Infrastructure Support (Secondary)

• Collaborate with the Windows team on Active Directory, Entra ID, Group Policy, DNS/DHCP, and authentication mechanisms.
• Support cross-platform identity and access management aligned with NIST access control policies.
• Assist with Windows Server administration and virtualization platforms within compliant environments.

Compliance, Security & Governance

• Ensure systems and processes adhere to NIST 800-171, and internal SSP (System Security Plan) requirements.
• Support export-controlled (EAR/ITAR) environments by enforcing access restrictions, logging requirements, and data segregation.
• Participate in cybersecurity audits, system assessments, and vulnerability scans.
• Maintain configuration baselines, security documentation, and evidence for compliance reviews.
• Implement and maintain system hardening standards and security controls across Linux and hybrid environments.

Monitoring, Logging & Incident Response

• Deploy and manage system monitoring tools (Prometheus, Grafana, Nagios, Zabbix).
• Maintain centralized logging (e.g., syslog, ELK/Elastic) in accordance with NIST audit and traceability requirements.
• Support incident response activities, root-cause analysis, and corrective actions.
• Contribute to continuous improvement of detection, response, and recovery processes.

Networking & Interoperability

• Troubleshoot networking services, secure remote access, firewall rules, VPN configurations, and cross-platform connectivity.
• Ensure secure communication between Linux systems and Windows infrastructure components.

DevOps & Automation (Preferred)

• Use automation tools (Ansible, Terraform, scripting) to support consistent, compliant system deployments.
• Assist with CI/CD pipeline integrations in regulated environments.

Documentation & Collaboration

• Maintain detailed runbooks, diagrams, SOPs, and configuration documentation aligned with compliance standards.
• Work closely with IT, security, engineering, and compliance teams to ensure seamless operations across controlled environments.

• 3 or more years of hands-on Linux systems administration experience (Ubuntu preferred).
• Strong understanding of system security, networking fundamentals, and hardening best practices.
• Experience supporting systems governed by NIST 800-53, 800-171, or similar frameworks.
• Ability to work within and maintain export-compliant (EAR/ITAR) environments.
• Experience with Bash scripting and automation.
• Familiarity with Windows Server, AD, Entra ID, and hybrid systems.
• U.S. person status as required by ITAR

• Experience with VMware, Hyper-V, or cloud platforms (AWS GovCloud, Azure Government, etc.).
• Experience with configuration management (Ansible, Salt, Puppet, Chef).
• Familiarity with SIEM tools and log aggregation platforms.
• Exposure to containerization (Docker) in regulated environments.

• Exceptional attention to detail, especially regarding documentation and compliance evidence.
• Strong communication and collaboration skills across technical and non-technical teams.
• Ability to balance security requirements with operational needs.

Echodyne’s technology is export controlled by the U.S. Government and we must evaluate an applicant’s eligibility to handle export-controlled information or obtain required Government authorizations.  Therefore, we will ask you as part of the application process to identify whether you are a U.S. Citizen or green card holder, or have asylum/refugee status in the U.S.
