Echodyne offers its radars to companies working in Automotive, Transportation, Critical Infrastructure Protection, Border Security, Smart Cities, Uncrewed Aircraft Systems (UAS), and Airspace Management including Urban Air Mobility (UTM).

We are seeking a skilled Systems Administrator with strong Linux expertise to support and enhance our primarily Windows‑based IT infrastructure. This role requires an individual who can operate confidently in hybrid environments while ensuring compliance with NIST cybersecurity frameworks and supporting export‑controlled systems and data (EAR/ITAR).

The successful candidate will serve as the organization's subject matter expert on Linux systems driving secure configurations, system hardening, cross‑platform integration, and documentation to meet both operational and regulatory requirements.

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 file systems, 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 , 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.

Dev Ops & 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…
