What are the responsibilities and job description for the 5.25 Robot Security & Linux Systems Administrator position at FieldAI?
Role: Robot Security & Linux Systems Administrator
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)
