About The Position

Northrop Grumman Defense Systems is seeking a Principal or Sr. Principal Guidance, Navigation, and Control (GN&C) Test Engineer to support the Sentinel (GBSD) program in the Strategic Deterrent Systems Division. The role is located in Roy, Utah, and provides technical leadership for the GN&C Integration and Testing campaign, including ground-based testing of inertial navigation sensors and GN&C-focused hardware-in-the-loop testing. The position may be filled at either the Principal or Sr. Principal level, based on qualifications. The successful candidate will lead or support multidisciplinary engineering teams developing, verifying, and validating navigation-sensor testing strategies; implementing GN&C algorithms in system-level test environments; creating tools to analyze GN&C performance; and assessing system performance against mission requirements. The role also involves flight-test accuracy analysis, systems integration and verification, test planning and execution, requirements development, and collaboration with systems engineering and test teams. The position requires an active U.S. Government Secret clearance at application and the ability to obtain and maintain SAP approval. Travel is 10% of the time. A standard 9/80 work schedule is offered, and relocation assistance may be available.

Requirements

Bachelor’s degree in a STEM discipline from an accredited university and 5 years of related experience, or a master’s degree and 3 years of related experience for the Principal level; the Sr. Principal level requires 8 years with a bachelor’s degree, 6 years with a master’s degree, or 4 years with a Ph.D.
U.S. citizenship and an active, current, in-scope U.S. Government Secret security clearance at the time of application, with an investigation date within the last 6 years.
Ability to obtain and maintain Special Access Program (SAP) approval within a reasonable period, as determined by the company.
At least 3 years of experience in guidance, navigation, or control algorithm development and/or flight or trajectory analysis for launch vehicle, missile, spacecraft, and/or aircraft applications.
Experience with hardware and software system integration and test principles.
Experience with systems engineering principles, including requirements decomposition and allocation.
Experience with aerodynamic modeling, flight mechanics, and missile or re-entry vehicle dynamics.
Experience in sensor navigation, including inertial, radio, and/or optical navigation techniques.
Experience with technical writing and documentation.
Experience with strategic missile guidance and implementation of guidance algorithms.
