Senior Principal Engineer - Guidance Navigation Controls

Northrop Grumman Northrop Grumman · Aerospace · El Segundo, CA +1 · Systems/Architecture/Test

Northrop Grumman is seeking a Senior Principal Engineer specializing in Guidance, Navigation, and Controls (GNC) for manned and unmanned air vehicles. The role involves researching, designing, developing, implementing, and testing GNC algorithms and software, including control laws, simulation models, and autonomy functions. The position requires experience with flight dynamics, control systems, MATLAB, Simulink, C/C++, Python, and a Secret security clearance.

What you'd actually do

  1. Support research and development of flight control algorithms for manned and unmanned air vehicles.
  2. Design, develop, implement, verify, and test algorithms, software, and simulation tools to perform guidance, navigation and control (GNC) of autonomous unmanned aircraft.
  3. Develop control laws to meet air vehicle performance, flying qualities and stability margin requirements, both on ground and in flight.
  4. Design outer and inner loop control laws, and associated logic and autonomy functions.
  5. Develop air vehicle system linear and non-linear dynamic simulation models and integrate models into software and hardware-in-the-loop simulation environments.
