Northrop Grumman Defense Systems is seeking a Principal GN&C Engineer/Sr. Principal GN&C Engineer. This opening is in Huntsville, AL or Roy, UT.
What you will get to do:
Hypersonic Testbed Guidance Navigation and Control (GN&C) Engineer
The engineer in this role will support the technical development of the Hypersonic Testbed vehicles' autopilot for precision at high Mach in Exoatmospheric and Endoatmospheric flight. The engineer is expected to have expertise in both classical and modern control theory for autopilot development (PID controller design, gain scheduling, optimal and robust control techniques). The engineer is responsible for the maturation of existing control algorithms and analysis tools as well as the tuning of the autopilot(s) for emerging missions supporting a variety of SDS Futures Programs. The engineer in this role will support covariance analysis and circular error probable accuracy assessment. In addition to a heavy focus on autopilot development the engineer in this role will:

• Participate in engineering review boards, technical interchange meetings and critical milestone reviews
• Determine and report incremental performance improvements
• Respond to analysis package requests
• Perform trajectory assessment and flight analyses
• Collaborate with a team of GN&C engineers in an Agile environment to meet critical milestones
• Develop and analyze GNC algorithms (Guidance, Navigation, Autopilot)
• Develop, verify, and validate complex 6 degrees of freedom vehicle models
• Model missile components such as inertial measurement units (IMU), electronic control actuators, and thrust vector control (TVC) systems.
• Use C++ and MATLAB and Object-Oriented design
• Conduct multidisciplinary research and collaborate with equipment designers and/or hardware engineers in the planning, design, development stages utilizing (M&S) tools systems for safety and mission critical analysis
• Work with the GN&C Flight Software Team to automatically generate code from high-level specifications or models, ensuring consistency and reducing manual errors
• Will serve on one or more Advanced Programs (SDS Futures' Group) initiatives in the hypersonic arena.

Basic Qualifications:
Principal GN&C Engineer:

• Bachelor's degree in STEM and 5 years of experience, 3 years of experience with master's degree, 0 years of experience with PhD.
• Must have an active U.S. Government DoD Secret security clearance at time of application, current and within scope, with an investigation date within the last 6 years
• Ability to obtain Special Access within a reasonable period as determined by the business needs of the company.
• 1 year of autopilot development and control theory specifically focused on tuning and implementing flight control algorithms.
• 2 years of experience with Agile Development with DoDAF standards and methods
• 2 years of demonstrated experience coding in a higher-level programming language (C, C++, MATLAB/Simulink, etc.)
• 3 years of demonstrated experience in guidance, navigation, or control algorithm development and/or analysis for launch vehicles, missiles, spacecraft, and/or aircraft.

Sr. Principal GN&C Engineer:

• Bachelor's degree in STEM and 8 years of experience, 6 years of experience with master's degree, 4 years of experience with PhD.
