(Senior) Embedded Software Engineer - Reliant

As an Embedded Software Engineer, you are a key member of our Architecture team, developing and implementing the core embedded software that enables our autonomous long-range VTOL platforms to operate safely, reliably, and intelligently in highly demanding operational environments. In this role, you will be dedicated to our Reliant platform – our next-generation long-range VTOL UAS designed for autonomous ISR missions in GNSS-denied and contested environments. You will contribute to mission-critical software that powers autonomous flight, resilient navigation, payload integration, and edge computing capabilities for defense and security customers worldwide. Together with our world-class team, you will push the boundaries of autonomous aviation, working closely with System Architecture, Flight Controls, AI, Hardware Development, Integration & Test, and Flight Operations to continuously improve Reliant's performance, reliability, and mission capabilities. What is your Day to Day Mission:• Design, implement, maintain, and optimize the Quantum-Systems embedded firmware stack for the Reliant platform • Develop safety-critical flight software for autonomous long-range VTOL operations • Design, implement, and validate new flight control, navigation, and mission management functionalities • Export flight control and navigation algorithms from MATLAB/Simulink and integrate them into the embedded autopilot framework • Implement, optimize, and maintain BSPs, peripheral drivers, communication interfaces, and sensor drivers • Develop embedded software for redundant and safety-critical avionics architectures • Integrate navigation sensors including IMUs, GNSS, magnetometers, air-data sensors, radar altimeters, and vision-based navigation systems • Support autonomous navigation capabilities in GNSS-denied environments through sensor fusion technologies • Develop and optimize communication interfaces for long-range command & control systems, payload communication, and ve
