Job Requirements Huntsville, AL Intel Agency (NSA, CIA, FBI, etc) Polygraph Unspecified Career Level not specified $140,000 - $160,000 Job Description GNC / Controls Software Engineer - Hypersonic Vehicles Huntsville, AL Who We Are Aurex is a mission-focused aerospace and defense company building the next frontier of deterrence. From hypersonics and missile defense to hardened networks and orbital systems, we design, test, and deliver the platforms that turn unproven ideas into battlefield-ready capability. Born in Huntsville and built for speed, Aurex brings together aerospace veterans, combat-tested operators, and forward-leaning technologists to solve problems that matter-fast. We move from whiteboard to warfighter with precision, clarity, and zero tolerance for fluff. Job Summary We are looking for a Senior GNC / Controls Software Engineer with extensive experience in developing guidance, navigation, and control algorithms and real-time flight software for high-speed aerospace vehicles. The ideal candidate will design, implement, and validate GNC software and control systems for hypersonic applications, ensuring performance, stability, and reliability under extreme flight conditions. Proficiency in simulation tools such as MATLAB/Simulink and real-time software development in C/C++ is required, with a primary focus on closed-loop GNC performance, robustness analysis, and flight software integration. Responsibilities Design, develop, and implement guidance laws, navigation filters, and flight control algorithms for hypersonic vehicles. Develop and optimize real-time embedded flight control software in C/C++ (or equivalent) for safety-critical systems. Create and maintain high-fidelity 6-DOF vehicle dynamics models and closed-loop simulations in MATLAB/Simulink. Perform linear and nonlinear stability analysis, robustness assessments, and Monte Carlo dispersion studies across the hypersonic flight envelope. Conduct software-in-the-loop (SIL), processor-in-the-loop (PIL), and hardware-in-the-loop (HIL) testing to verify GNC performance. Integrate and tune multi-sensor navigation solutions (INS/GPS and additional aiding sensors) for accurate state estimation. Optimize control system performance for stability, tracking accuracy, and disturbance rejection under thermal, structural, and atmospheric uncertainties. Collaborate with cross-functional teams, including aerodynamics, propulsion, structures, and systems engineers, to ensure seamless GNC integration. Support flight test planning, data analysis, and post-flight reconstruction, iterating designs based on test results. Basic Qualifications Active DoD Secret Clearance Work in person at our corporate headquarters in Huntsville, AL.
