Senior GNC Engineer (Navigation)
STEM Boomerang•Rio Rancho, NM
•Onsite
About The Position
We are seeking a Senior GNC Engineer to develop advanced navigation solutions for Castelion's long-range hypersonic strike vehicles. This role is critical to enabling precise state estimation across all mission phases, including GPS-denied environments. You will work hands-on with multidisciplinary engineering teams to design, analyze, implement, and validate multi-sensor navigation algorithms, including star tracker-based alternative navigation and sensor fusion architectures, in a fast-paced, hardware-driven environment.
Requirements
- Bachelor's, Master's, or PhD in Aerospace Engineering, Electrical Engineering, or related field
- 5+ years of experience in navigation algorithm development, analysis, and validation for aerospace or high-performance dynamic systems
- Strong background in estimation theory, including Extended Kalman Filters (EKF) and multi-sensor fusion
- Experience with inertial navigation systems (INS) and integration with external aiding sources (e.g., GNSS, star trackers, or similar sensors)
- Familiarity with alternative navigation (alt-nav) techniques for GPS-denied environments
- Proficiency in modeling and simulation tools such as MATLAB/Simulink or equivalent
- Experience with 3DOF and 6DOF simulation environments and real-time implementation of navigation algorithms
- Strong understanding of sensor error modeling (IMUs, star trackers, etc.) and calibration techniques
- Familiarity with flight software integration and real-time embedded systems
- Strong problem-solving mindset, thriving in a fast-paced, hardware-rich, high flight cadence environment
