Senior GNC Engineer
Position Overview:
High-performance maneuvering demands an extremely responsive airframe and control system. As the Senior GNC Engineer (Controls), you will be part of the team that develops high fidelity plant models describing Inversion’s reentry vehicles and you own the development of the flight control system that allows our vehicles to track aggressive guidance commands quickly and crisply. In this role, you will:
Develop plant models of the vehicle and its subsystems aerodynamics, actuators, sensors, and structural dynamics at the fidelity needed for control design and verification
Design and analyze high-rate flight control loops that stabilize a statically unstable airframe across the flight envelope
Deliver the autopilot bandwidth and command tracking needed to respond quickly to real-time guidance commands
Quantify and manage stability margins in the presence of sample rate, latency, actuator dynamics, and structural mode constraints
Integrate and exercise control designs in 3-DOF and 6-DOF flight simulations, including Monte Carlo robustness assessment across dispersed conditions
Carry control algorithms through implementation in real-time flight software and hardware-in-the-loop testing
Work closely with the guidance, aerodynamics, structures, and avionics teams to close vehicle-level performance
Required Qualifications:
Bachelor's degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, a related field, or equivalent experience
Typically, 5+ years of applicable experience designing and testing control systems for aerospace vehicles
Experience building plant models of aerospace systems, including aerodynamic, actuator, and sensor dynamics and controlling open-loop unstable systems
Experience with high-rate digital control design, including discretization, sample rate selection, and the management of latency and computational delay
Experience developing and exercising 3-DOF and 6-DOF flight simulations
Strong fundamentals in classical and modern control theory, including frequency-domain loop shaping, stability margin analysis, and state-space methods
Proficiency with MATLAB/Simulink and programming languages such as Python or C++
Demonstrated excellent verbal and written communication skills
Capable of working in a dynamic, fast-paced startup environment
Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.
Desired Qualifications:
Master's or PhD in Aerospace Engineering, a related field, or equivalent experience
Experience with autopilot design for reentry, hypersonic, missile, or other high-dynamic-pressure flight systems
Experience applying frequency-domain loop shaping to flight control design, including the construction of phase and gain budgets and the management of two-sided stability margins for conditionally stable systems
Experience modeling actuator nonlinearities, including rate and position limits, and their effect on stability of unstable plants
Experience with flexible-body dynamics and aeroservoelastic effects, including structural mode filtering
Experience with system identification and control-relevant model updates from ground or flight test data
Experience implementing control algorithms in real-time flight software on embedded hardware
Hardware-in-the-Loop (HITL) test experience
Prior experience working in startups and/or small independent teams
