(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 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 campaigns
• Debug and trace embedded software to improve robustness, code coverage, and system reliability
• Maintain bootloaders, secure firmware update mechanisms, and firmware deployment processes
• Improve firmware build systems, CI/CD pipelines, and automated testing infrastructure (GitLab CI)
• Support production, manufacturing, and hardware validation tools
• Collaborate closely with AI and Edge Computing teams to integrate onboard processing capabilities into embedded flight systems
• Contribute to software architecture, coding standards, and continuous improvement of development processes
