• Deep understanding of spacecraft attitude dynamics, orbital mechanics, environmental perturbations, and actuator/sensor physics
• Significant experience with estimation and filtering (EKF, UKF, batch least squares), sensor fusion, covariance analysis, and navigation performance assessment
• Experience designing control laws and performing stability, robustness, and frequency-domain analysis
• Demonstrated ability to develop and maintain complex high-fidelity simulations and Monte Carlo frameworks
• Experience testing and integrating GNC algorithms with flight hardware, including star trackers, IMUs, reaction wheels, GN&C avionics, and propulsion components
• Experience defining subsystem requirements, verification plans, and participating in formal design reviews
• Ability to lead cross-disciplinary technical efforts and deliver results with minimal direction
• Strong communication skills and ability to mentor and guide less experienced engineers
• U.S. Citizen and eligible for DoD Secret or TS/SCI clearance

PREFERRED SKILLS AND EXPERIENCE

• Experience developing GNC systems for proximity operations, formation flying, optical navigation, autonomous maneuvering, or precision pointing missions
• Expertise with FDIR related to GNC components, including failure detection, isolation, and recovery techniques
• Experience with autonomous guidance or onboard trajectory optimization
• Familiarity with safety-critical or fault-tolerant flight software architectures
• Experience with real-time operating systems, embedded software, and hardware-in-the-loop testbeds
• Track record of technical leadership, ownership of major subsystem design, or architecting full GNC solutions

COMPENSATION

• Base Salary: $170,000 - $255,000
• Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience.
