Junior GNC Engineer (Aerospace Engineer)

Command Post Technologies, Inc. is seeking a Junior GNC (Guidance, Navigation, and Control) Engineer to support hypersonic research efforts of the NSWCDD in Dahlgren, VA. This role provides technical expertise across system modeling, simulation, algorithm development, data analysis, and integration activities in support of weapon system development, performance assessment, and mission engineering. The Engineer will directly support government technical leads and collaborate with associated subsystem SMEs to deliver analytical rigor, modeling capability, and engineering insight into guidance, navigation, and control solutions used in government test and evaluation environments.

Responsibilities:

• Develop, implement, and refine GNC algorithms for guidance laws, control loops, navigation filters, and state estimation.
• Support weapon system modeling and simulation, including 6 DOF (six degrees of freedom) simulation environments and subsystem integration.
• Perform trajectory analysis, mission performance evaluations, and control system stability assessments.
• Develop navigation solutions integrating IMUs, GPS, INS, seekers, and other sensor modalities.
• Conduct Monte Carlo analysis, uncertainty modeling, and system performance sensitivity studies.
• Implement GNC prototypes in MATLAB/Simulink, Python, C/C++, or equivalent simulation frameworks.
• Analyze telemetry, flight test data, and HWIL/SIL outputs to validate system performance.
• Support requirements decomposition, interface definition, and subsystem integration with E20 system engineering teams.
• Document models, test results, algorithm behavior, and performance in technical reports and presentations.
• Participate in technical reviews, design sessions, and engineering working groups with government and contractor personnel.
