Requirements

Bachelor’s degree in Aerospace, Mechanical, or Electrical Engineering, or related field.
7+ years of experience in GNC algorithm design or analysis for missile, interceptor, or launch vehicle programs.
Proficiency in MATLAB/Simulink, C++, or Python for modeling, simulation, and algorithm development.
Strong understanding of flight dynamics, control theory, and state estimation.
U.S. citizenship with a TS/SCI clearance.

Nice To Haves

Advanced degree (MS/PhD) in Aerospace or related field.
Experience supporting MDA, USAF, USN, or DARPA missile programs.
Familiarity with hypersonic or boost-glide vehicle guidance systems.
Experience with embedded flight software integration or RTOS environments (e.g., GreenHills).
Hands-on experience with HWIL setups, sensor integration, and post-flight data analysis.
Strong communication skills and the ability to lead small, agile technical teams.

Responsibilities

Developing and analyzing guidance, navigation, and control algorithms for missile and interceptor systems.
Performing system-level modeling and simulation (6-DOF, Monte Carlo, trajectory optimization).
Conducting trade studies and sensitivity analyses to optimize performance and reliability.
Integrating sensor data (IMU, GPS, seeker inputs) into state-estimation filters (Kalman, EKF, UKF).
Supporting hardware-in-the-loop (HWIL) testing and post-flight data analysis.
Collaborating with flight software, systems, and hardware teams to ensure end-to-end system performance.
Documenting and presenting technical results to government customers and internal leadership.
Contributing to iterative design cycles, participate in technical reviews, and ensure compliance with mission assurance and quality standards.
