Northrop Grumman Northrop Grumman · Aerospace · San Diego, CA +2 · Systems/Architecture/Test

Northrop Grumman is seeking an Associate Systems Modeling Simulations Engineer/Systems Modeling Simulations Engineer to support Operations Analysis and Modeling and Simulation (M&S) activities for Aeronautics Systems. The role involves planning and executing studies, developing complex algorithms and scripts, and creating/maintaining analytical models and simulation tools using languages like MATLAB/Python/Simulink. The position requires a STEM degree and an active U.S. Government security clearance.

What you'd actually do

  1. Plan and execute studies (trade studies, sensitivity analyses, Monte Carlo), analyze results, and visualize findings to drive data-informed decisions.
  2. Develop complex algorithms and scripts for use in mission simulation tools.
  3. Develop, integrate, and maintain analytical models and simulation tools (e.g., MATLAB/Python/Simulink or similar) to evaluate system performance and mission effectiveness.
  4. Learn and understand Tactics, Techniques, and Procedures (TTPs) to support blue/red kill chains across multiple security environments, programs, architectures, and platforms.
  5. Solicit input from various stakeholders, synthesize data, and communicate results to various levels of leadership.
