Join JRC's Strategic Defense & International Operations (SDIO) Team!We are seeking a GNC Engineer (Aerospace Engineer) to develop and refine guidance, navigation, and control algorithms supporting advanced weapon system modeling, simulation, and flight performance analysis. This role involves trajectory analysis, sensor integration, 6 DOF simulation, telemetry evaluation, and control system development using MATLAB/Simulink, Python, and C/C++ in support of mission-critical aerospace and defense programs.
What You'll Do- 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.
What You Bring to the Table- Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Physics, or related discipline (Master's preferred).
- 4+ years' experience in GNC engineering, missile guidance, flight controls, or related system modeling.
- Proficiency in MATLAB/Simulink and at least one programming language (Python or C/C++).
- The successful candidate shall have experience with guidance algorithms (proportional navigation, pursuit guidance, optimal guidance, intercept geometry), navigation & estimation, Kalman filtering (EKF/UKF), inertial navigation, GPS/INS integration, sensor fusion, control engineering, PID, LQR, state space control, autopilot design, stability & robustness analysis, M&S (Modeling & Simulation), MATLAB/Simulink, Python (NumPy/SciPy), C/C++ for embedded or real time simulation, and familiarity with 6 DOF modeling.
- Ability to work with E20 technical SMEs to develop or refine analytical tools, performance models, or algorithmic improvements.
- Ability to obtain and maintain a DoD Secret clearance (current Secret preferred).
☆
Bonus Points- Familiarity with hardware in the loop (HWIL) or software in the loop (SIL) environments is a plus.
- Experience supporting missile systems, unmanned systems, or weapons/flight dynamics programs.
- Experience supporting NSWCDD, NAVSEA, or other DoD weapons engineering divisions.
- Experience with aerospace flight test data analysis or guidance law verification.
- Knowledge of seeker modeling, sensor suite integration, or autopilot tuning.
