About The Role: Join our team developing cutting-edge software for the Quarterhorse supersonic unmanned aircraft. You'll work with C++ and web technologies (TypeScript/JavaScript) to build control systems for both remotely piloted (HOTAS) and autonomous flight modes. This role includes designing and implementing intuitive user interfaces, ranging from hands-on control to point-and-click autonomy management.

Responsibilities: • Support the development and implementation of flight software and guidance and control algorithms

• Implement, integrate, and test control algorithms in simulation, embedded, and hardware-integrated environments

• Assist with control law development, tuning, and validation for vehicle stability and performance

• Develop software interfaces, messaging, and integrations between flight and mission subsystems

• Analyze test data, troubleshoot system behavior, and support improvements to software and control performance

• Collaborate across software, GNC, avionics, and vehicle engineering teams to validate integrated systems

Requirements: • Pursuing a degree in Aerospace Engineering, Computer Engineering, Computer Science, Electrical Engineering, or a related technical field

• Background in either software development with exposure to GNC/controls, or GNC/controls with experience implementing software

• Experience with C++, C, Python, MATLAB/Simulink, or similar programming and engineering tools

• Familiarity with controls, dynamics, simulation, embedded systems, or hardware/software integration

• Hands-on experience through internships, coursework, research, or technical projects

• Strong understanding of engineering first principles

• Demonstrated ability to work within cross-functional teams

• Excellent written and verbal communication skills

• GPA of 3.0 or above
