(Senior) Embedded Software Engineer - Reliant

Job description

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 vehicle subsystems Support the integration of modular payloads including EO/IR sensors, SIGINT, EW, SAR, CRPA, and future mission systems Contribute to robust firmware architectures enabling reliable operation in contested and degraded environments Build, document, maintain, and continuously improve autopilot firmware Prepare flight test releases, create flight test tickets, analyze flight logs, and support flight test campa…
