FieldAI
5.25 Robot Security & Linux Systems Administrator
FieldAI, Irvine, California, United States, 92713
Overview
This role combines deep Linux systems expertise with a focus on securing robotic platforms and their supporting infrastructure. The engineer will be responsible for hardening Ubuntu-based systems, securing robotic communications, enforcing encryption and privacy standards, and managing the lifecycle of critical Linux services used in autonomous and networked robots. Core Responsibilities
Manage and secure Ubuntu and Debian-based systems used in robotic and embedded environments. Maintain system uptime, kernel updates, and package management with strong focus on security and compliance. Lock down robotic OS images, enforce secure boot configurations, and manage patching for real-time kernels. Conduct system and network vulnerability assessments across robotic subsystems (firmware, middleware, and cloud integrations). Harden communication layers — DDS/ROS2, MQTT, BLE/Wi-Fi, and WebRTC — ensuring encryption, authentication, and message integrity. Audit and remediate weak cryptographic implementations (e.g., Blowfish ECB, LCG-based key generation) and enforce modern cryptography standards (AES-GCM, ECC, TLS 1.3). Protect telemetry and sensor data from unauthorized external connections and persistent unencrypted transmission. Oversee user access, SSH configurations, and credential management across Linux-based robotic endpoints and servers. Implement centralized monitoring, logging, and intrusion detection (CrowdStrike, OSSEC, Wazuh, or similar). Build and maintain automation scripts (Bash, Python, Ansible) for configuration management and compliance enforcement. Support DevOps and engineering teams with CI/CD security, container hardening, and secure deployment of robotic software. Maintain compliance documentation and baselines aligned with frameworks such as NIST 800-171, CMMC, and SOC 2. Required Skills & Experience
Expert in Ubuntu/Linux systems administration, including kernel tuning, network stack, and user management. Proven experience with robotic or IoT systems security, especially involving ROS2/DDS, MQTT, or embedded Linux. Strong background in applied cryptography, secure key management, and encryption at rest/in transit. Familiarity with real-time Linux (RT Preemption Patch) and resource-constrained environments. Hands-on experience with automation and infrastructure tools (Ansible, Terraform, or equivalent). Ability to analyze binaries, firmware, and system daemons for vulnerabilities. Scripting and debugging skills in Bash, Python, and Go. Experience with secure cloud integration for robotic telemetry and command services (AWS, Azure, or private clouds). Preferred Background
5+ years in Linux systems administration, cybersecurity, or robotics engineering. Experience mitigating vulnerabilities in robotic or autonomous systems, including hardware interfaces and telemetry layers. Prior work in regulated or high-assurance environments (defense, industrial automation, medical robotics). Certifications: LPIC, RHCE, CISSP, or GIAC (preferred but not required) Salary:
$115K to $140K/year
