• 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
