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.

What You'll Get To Do:

• 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.

Position Benefits:

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

• Medical, Dental & Vision coverage
• 401k
• Educational Assistance
• Life Insurance
• Employee Assistance Programs & Work/Life Solutions
