GNC Engineer; Aerospace Engineer Security Clearance

Position: GNC Engineer (Aerospace Engineer) with Security Clearance
Who We Are ( video ) At JRC, we tackle some of the toughest challenges faced by the Department of Defense (DoD) and other government agencies. Our expertise in engineering innovation and semiconductor technologies allows us to deliver mission-critical microelectronics solutions, aerospace systems engineering, and cutting-edge research and development. By joining JRC, you'll be part of a team that supports strategic deterrence and defense missions, playing a crucial role in ensuring the safety and security of the United States and its allies.

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
* An active DoD security clearance at the SECRET level or above (or have held an active DoD clearance within the last 2 years)
* 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 (Num Py/Sci Py), 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. At JRC we offer...
* A competitive compensation package
* An exceptional employee benefits program, providing support for our team members' well-being and success
* The chance to contribute to a high-profile Department of Defense programs and make a positive impact
* A collaborative work environment where teamwork, creativity, and innovation thrive
* Opportunities for professional growth and development, helping you advance your career
