5.25 Robot Security & Linux Systems Administrator

Field AI is transforming how robots interact with the real world. We are building risk-aware, reliable, and field-ready AI systems that address the most complex challenges in robotics, unlocking the full potential of embodied intelligence. We go beyond typical data-driven approaches or pure transformer-based architectures, and are charting a new course, with already-globally-deployed solutions delivering real-world results and rapidly improving models through real-field applications.

Job Summary :

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.

What You'll Get To Do

• 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.
