## Description

You're a GNC software engineer who wants real ownership over the guidance and control systems of a clean-sheet autonomous aircraft. You work from first principles, you write the simulation and flight code yourself, and you work closely with hardware and software teams to get the aircraft flying. You care deeply about how systems behave in the real world-not just in simulation-and you're motivated by building control architectures that are robust, testable, and ready for flight., * Develop and implement guidance, navigation, and control systems for our products

 * Engage in multi-disciplinary aircraft trades and help define the overall system architecture
 * Build and maintain 6-DOF dynamics and simulation models used for control design, analysis, and validation
 * Develop tooling to automate control design, monte carlos, and simulation validation
 * Work closely with peers across engineering disciplines to define the control schemes and mechanisms for our products
 * Support flight and ground test operations
 * Conduct post flight/test reviews and correlate performance with analysis for continuous improvement on predictions
