No H1B

U.S. Citizen Only

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
