## Description

As a GNC Software Engineer you will develop, implement, and validate guidance, navigation, and control algorithms in software for flight systems in aerospace and defense applications. This role translates GNC concepts into robust, flight-ready software, working across simulation, embedded implementation, and hardware-in-the-loop environments. You will own well-defined subsystems or features, and collaborate closely with systems, avionics, propulsion, and test teams to ensure GNC software meets performance, safety, and mission requirements., * Design, implement, and maintain flight GNC software for aerospace applications

 * Translate GNC requirements and models into efficient, reliable embedded software
 * Develop and execute simulations to evaluate guidance, navigation, and control performance
 * Support system integration, hardware-in-the-loop (HIL), and flight test activities
 * Analyze test and flight data to assess performance and drive improvements
 * Contribute to requirements definition, verification, and traceability for GNC functions
 * Identify and mitigate technical risks through analysis, testing, and peer review
 * Collaborate cross-functionally with systems, avionics, software, and test engineers
 * Document designs, analyses, and test results for internal and external stakeholders
