Senior Guidance, Navigation, and Controls Engineer (GNC)

About This Role

As a Senior Spacecraft Guidance, Navigation, and Controls (GNC) Engineer, you will own the full life cycle of GNC development at Varda, from design through to unit, hardware-in-the-loop, on-vehicle functionality, and flight testing. You will perform system analyses, including simulations and Monte Carlo, to satisfy specifications and requirements and to drive system-level architectural and business decisions. You will contribute to a sophisticated multi-degree of freedom in-house aerospace simulation and test framework and develop and maintain design descriptions and supporting documentation. You'll see end to end execution of the GNC subsystem from initial analysis/design through vehicle integration, mission planning and flight through support of on-orbit and reentry mission operations.

Responsibilities

• ADCS hardware performance specification including sizing of reaction wheels, torque rods, IMU/GPS, and star trackers
• Design and implementation of autonomous satellite attitude control, collision avoidance, orbital rendezvous, burn planning and atmospheric re-entry algorithms
• Perform trajectory design, optimization, and dispersion analysis for the reentry of a space capsule
• Develop 6 degree of freedom vehicle simulation using C++, Python and MATLAB/Simulink
• Running Monte Carlo analysis to characterize performance of new vehicle and mission capabilities
• Integration and testing of GNC sensors, actuators, and software in hardware-in-the-loop environment
• Design and implementation of ground tooling necessary to facilitate fully automated maneuver responsibility and maneuver scheduling decisions
• Monitoring on-orbit system performance; troubleshooting where necessary
• Coordination with other spacecraft operators, 3rd party agencies, and the US government

Basic Qualifications

• B.S. degree in aerospace, mechanical, electrical engineering, physics, or related field
• 5+ proven years of experience, or PhD with 3+ years of relevant experience
• Demonstrated knowledge in designing, modeling, testing, and flying aerospace guidance, navigation, and control systems
• Highly adept software and model development skills, particularly in C++/Python
• Understanding of orbital mechanics, modeling and simulation, and software development
• Experience anchoring/fitting first principles models to test data or high-fidelity external simulations
• Proven system engineering and configuration management skills
• Excellent written and verbal communication skills

Preferred Skills and Experience

• Master's degree in engineering or physics
• Experience with spacecraft attitude determination and control system design
• Experience with GMAT, POST2, or similar tools
• Understanding of multi-body dynamics, flexible body dynamics, gas dynamics, fluids, and thermodynamics
• Experience developing and verifying physical models for the purpose of control design, component sizing, and system performance evaluation
• Experience supporting safety critical flight tests or spacecraft
• Ability to continuously manage risk and provide solutions with lean and state of the art software development techniques

Pay Range

• Salary range: Senior: $169,067 - $216,031/per year
• This role is on-site in El Segundo, CA
• Leveling and base salary is determined by job-related skills, education level, experience level, and job performance
• You will be eligible for long-term incentives in the form of stock options and/or long-term cash awards
