Northrop Grumman Defense Systems is seeking a Principal/Sr. Principal Engineer Systems Modeling Simulation for Launch Support Systems (LSS). This position is based in Roy, UT and supports the Sentinel program.

• Lead and execute Modeling, Simulation, & Analysis (MS&A) initiatives for the LSS team.
• Develop high fidelity models that capture mechanical loading and system level behavior.
• Create and run Multibody Dynamics (MBD) simulations for flight operations hardware and related test fixture configurations, covering rigid body, flexible body, and deployment kinematics.
• Integrate MBD results with other physics domains (e.g., flexible body stress predictions, thermal, fluid) to improve overall fidelity.
• Correlate analytical models with experimental data (vibration, modal, static tests) to validate accuracy.
• Perform structural analysis studies (static, modal, frequency response) to verify loads, stresses, deflections, fatigue life, and safety margins versus material limits.
• Automate workflows using MATLAB, Python, or comparable scripting tools for data processing, model generation, and results correlation.
• Collaborate cross functionally to align simulation efforts with program milestones.
• Provide design recommendations that optimize strength, weight, and durability.
• Drive continuous improvement of simulation methods and contribute to technical reviews, documentation, and lessons learned archives.
• Prepare clear, concise analysis reports for design reviews, analysis reviews, and technical baseline updates.

As a full-time employee of Northrop Grumman, you are eligible for our robust benefits package including:
