Join Northrop Grumman on our continued mission to push the boundaries of possible across land, sea, air, space, and cyberspace. Enjoy a culture where your voice is valued and start contributing to our team of passionate professionals providing real-life solutions to our world’s biggest challenges. We take pride in creating purposeful work and allowing our employees to grow and achieve their goals every day by Defining Possible. With our competitive pay and comprehensive benefits, we have the right opportunities to fit your life and launch your career today.
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:
This positions standard work schedule is a 9/80. The 9/80 schedule allows employees who work a nine-hour day Monday through Thursday to take every other Friday off. This role may offer a competitive relocation assistance package.
