Be a part of our team of Guidance, Navigation and Control (GNC) engineers within the System Engineering, Integration and Test (SEIT) group.  The GNC Team supports all Northrop Grumman Armament System programs in the product areas of medium and large caliber ammunition, precision and guided projectiles, air defense systems, and miniature strike munitions.

We utilize the latest tools and processes available to generate guidance algorithms, controls, navigation filters, system architecture models and performance simulations. Our GNC engineering methods follow Model Based Engineering (MBE) principles utilizing MathWorks Modeling & Simulation (M&S) tools, within our digital engineering toolsets.

Interdisciplinary engagements with Mechanical, Electrical, Aeronautical, Systems, Test and other Engineers are critical. Collaborate and coordinate with key stakeholders across the SEIT group, technical/project lead engineers, program managers, and integrated product teams. Support GNC project execution, technical oversight and engineering reviews as required.


Primary responsibilities of this position include development of innovative flight control architectures, physical and mathematical model generation, adaptation of GNC subsystems to airframe aerodynamic models, prototype system design, build, test, design verification and iterative model validation through test data analyses. These may also include:

  • Support trade studies and develop algorithms, models, and simulations of GNC subsystems to satisfy top level system specifications and requirements.
  • Capture GNC architectures and physics-based models of major subsystems and components, enabling system performance simulations in key use environments.
  • Support GNC optimization through high fidelity simulations, including six degrees of freedom (6 DOF) constructs and Monte Carlo statistical analyses.
  • Assist prototype build, test, and potential failure investigations to identify root causes and corrective actions that resolve observed system performance issues.

This position can be filled at a higher Engineering grade level depending on years of experience and/or education.

Basic Qualifications for Principal GNC Engineer:

  • B.S., M.S. or PhD in Electrical, Mechanical, Aerospace or Systems Engineering or a closely related field. 
  • At least 5 years of Industrial work experience in model development, requirements definition, GNC algorithm analysis and synthesis and familiarity with both modern and classical control design techniques.
  • Ability to travel for work 10% of the time.
  • Ability to obtain a DoD Secret (or higher) Security Clearance.

Basic Qualifications for Sr. Principal GNC Engineer:

  • Includes all the above with the addition of at least 9 years of GNC Engineering experience.

Preferred Qualifications:

  • An ideal candidate will have experience in development of Integrated GNC subsystems for precision guided weapons.
  • Knowledge and experience in one or more related disciplines such as: guidance laws, navigation, autopilots, actuation, seekers, and software development as well as MBE and M&S principles are desired.
  • Experience with MathWorks tools is also desired.

Salary Range: $96,600 USD - $144,900 USD
