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.
This position is 100% on site in Chandler, AZ (strongly preferred). Remote candidates may also be considered
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
Basic Qualifications
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
Preferred Qualifications
Ability to obtain and maintain Top Secret and/or Special Access Program (SAP) access; active TS/SAP is highly preferred
Experience in one or more of the following areas:
Missile/interceptor guidance, navigation, and control (GNC)
RF or EO/IR seeker/sensor modeling
Integrated air defense systems (IADS) or threat modeling
Electronic attack, electronic protection, and countermeasures modeling
Survivability, lethality, and vulnerability analysis at the weapon or mission level
Familiarity with Model‑Based Systems Engineering (MBSE) tools and digital engineering practices (e.g., Cameo/SysML) and their use in linking models to requirements
Experience with real‑time simulation and man‑in‑the‑loop or hardware‑in‑the‑loop test environments
Experience working within an Agile development workflow using tools such as Jira and Bitbucket/Git
