Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.

Northrop Grumman is seeking a Systems Engineer - Level 5, Mission Modeling Simulation, located in Chandler, AZ. This position will support mission‑level and system‑level modeling, simulation, and analysis for advanced missile and interceptor systems. You will design and implement physics‑based models, construct mission and engagement scenarios, and perform quantitative analyses that support requirements development, design trades, and performance verification. This role is ideal for an experienced engineer who enjoys hands‑on modeling and analysis while collaborating closely with cross‑functional teams.

You will work with various engineering disciplines (systems, GNC, seeker/sensor, software, mission, integration & test, etc.) to:

• Develop and integrate mission‑level and system‑level performance models, algorithms, and simulations of missiles, interceptors, sensors, threats, and command‑and‑control systems
• Perform operations and behavior analysis, mission effectiveness studies, and assess architecture alternatives for delivering an effect or capability within a broader campaign, including end‑to‑end engagement and campaign‑level assessments
• Implement algorithms and analysis scripts in MATLAB, Python, C/C++ or similar tools to support constructive and real‑time simulations
• Build operationally relevant scenarios to assess end‑to‑end performance against representative air and missile threats
• Perform trade studies, sensitivity analyses, and design of experiments to quantify performance, robustness, and mission utility
• Document assumptions, methods, and results in clear technical reports and present findings to project teams and technical reviewers

• U.S. citizenship is required
• Active US Government Secret security clearance
• Bachelor’s degree in a STEM discipline (Systems, Aerospace, Mechanical, Electrical Engineering; Physics; Applied Mathematics; Computer Science; etc.) and 12 years of related experience in modeling and simulation or operations analysis; or Master’s degree and 10 years; or Ph.D. and 8 years
• Demonstrated experience in modeling, simulation, and analysis for defense systems, preferably missiles, interceptors, or related weapon/mission systems
• Hands‑on experience with operations analysis and/or virtual simulation tools (e.g., AFSIM, NGTS, Brawler, STK, MATLAB/Simulink)
• Strong background in probability, statistics, and design of experiments applied to weapon system and mission performance
• Proficiency in MATLAB, Python, C/C++ or similar languages for algorithm development, model integration, scripting, and data analysis
• Experience modeling operational environments and performing mission effectiveness trade studies
• Excellent written and verbal communication skills, including briefing complex analysis outcomes to program and customer leadership
• Demonstrated resolve to drive tasks to completion, both independently and in collaborative teams, and possess strong mentoring / training skills

• Ability to obtain and maintain Top Secret and/or Special Access Program (SAP) access; active TS/SAP is highly preferred
• Experience in one or…
