Join L3H and the Liberator team to develop command and control software for systems operating in real-world deployed environments. You will turn complex mission and platform needs into secure, resilient software that connects embedded computing, communications, and hardware at the edge. This is a hands-on role for an engineer who enjoys taking a system from bench bring-up through integration, verification, and field-ready deployment.

• Design, develop, integrate, and sustain embedded command and control software for CSE & Liberator deployed systems.
• Build, configure, harden, and maintain embedded Linux images on ARM and single-board-computer platforms.
• Implement secure platform capabilities, including signed boot, chain of trust, TPM2, U-Boot, keys and OTP, measured boot, and LUKS disk encryption.
• Develop Python services and automation for networked applications, messaging, concurrency, and protocol handling; contribute C/C++ firmware for microcontroller-class platforms as needed.
• Bring up and debug hardware-in-the-loop and bench environments using serial interfaces, GPIO, digital I/O, wiring diagrams, and board-level electrical interfaces.
• Configure deployed Linux systems, including networking, firewall rules, systemd services, time synchronization, logging, and provisioning workflows.
• Develop and execute test procedures, investigate defects, and produce verification evidence supporting integration and release readiness.
