Staff GNC Analysis Engineer

Ursa Major develops high-performance propulsion and defense systems for aerospace and national security applications. The Staff GNC Analysis Engineer will lead development of vehicle guidance, navigation, and control capabilities, including system design, algorithm development, simulation, embedded implementation, and hardware-in-the-loop validation. The role works cross-functionally to develop and validate flight-ready control systems.

Responsibilities:

• Design, implement, and maintain flight GNC systems for aerospace applications
• Translate GNC requirements into models and into efficient, reliable embedded software
• Develop and execute simulations to evaluate guidance, navigation, and control performance
• Coordinate with design to ensure that vehicle design parameters align with control system requirements
• Support system integration, hardware-in-the-loop (HIL), and flight test activities
• Analyze test and flight data to assess performance and drive improvements
• Contribute to requirements definition, verification, and traceability for GNC functions
• Identify and mitigate technical risks through analysis, testing, and peer review
• Collaborate cross-functionally with mechanical design, avionics, software, and test engineers
• Document designs, analyses, and test results for internal and external stakeholders

Requirements:

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Computer Science, or related field
• Professional experience developing GNC models and algorithms for aerospace or defense systems
• Strong understanding of classical control, estimation, and vehicle dynamics
• Experience implementing algorithms in MATLAB/Simulink, C/C++, or Python or equivalent
• Ability to work effectively across disciplines and communicate technical concepts clearly
• Ability to work effectively in teams or individually
• Must be a U.S. Person (this includes U.S. Citizens and Permanent Residents)
• Eligibility to obtain and maintain a U.S. Security Clearance
• Master's degree or Ph.D. in a relevant engineering discipline
• Experience with navigation sensors (IMUs, GPS, star trackers, etc.) and state estimation techniques (e.g., Kalman filtering)
• Exposure to hardware-in-the-loop testing, flight testing, or operational flight systems
• Familiarity with safety-critical or regulated development environments (e.g., DO-178 or equivalent processes)
• Prior experience supporting aerospace or defense programs through integration and test phases
• Professional experience developing flight software for aerospace or defense systems
• Experience developing simulations to evaluate guidance, navigation, and control performance
• Experience leading development of GN&C standards
