About the Role:
Come join the growing Theater Strike Weapon System program portfolio, including Conventional Prompt Strike, Hypersonic Weapon Systems, Advanced Glide Systems, Hypersonic Payload Delivery systems, and other new and dynamic programs. In this role as a GNC engineer, you may be involved in many of the following activities:
• Apply missile guidance, navigation, and control expertise to algorithm development, signal and data processing, modeling, and simulation
• Integrate Matlab/Simulink models into a 6-DOF C++ simulation
• Develop high fidelity models and simulation software
• Develop new source code in C++ and Python
• Modify code in C++, C, Matlab, Simulink, Fortran, Python, Linux shell, and YAML
• Create unit tests
