MTSI is seeking to hire a motivated engineer with experience in modeling & simulation. The candidate will support a team delivering high-fidelity modeling, simulation, and analytical products of kinetic weapon system concepts for the Missile Defense Agency. This role offers the opportunity to work on high visibility, cutting-edge missile system programs and contribute to innovative solutions for national defense. Key Responsibilities: Support mission-level modeling and simulation of weapon systems using AFSIM and related tools. Develop and maintain C++ models for fire control, engagement kinematics, and missile system performance. Conduct performance analysis and scenario-based simulations to evaluate GNC and fire control effectiveness. Collaborate with GNC engineers to integrate models, run large-scale simulations, and analyze results for missile and kinetic weapon concepts. Develop analytical products, technical reports, briefings, and visualizations to support DoD program decisions. Contribute to ongoing modeling and simulation efforts, including tool enhancement and scenario development. Qualifications: U.S. Citizenship required (and ability to obtain security clearance). Bachelor’s degree in Aerospace Engineering, Computer Science, Electrical Engineering, or a related field (MS preferred). 10+ years of experience in modeling & simulation Strong software development skills with solid understanding of object-oriented programming principles in C++. Experience developing, modifying, and debugging complex simulation models in C++. Familiarity with 6-DOF simulations, fire control systems, engagement modeling, or GNC concepts. Proficiency with modeling and simulation tools such as AFSIM, MATLAB, and Python. Ability to perform detailed system-level performance analysis and support requirements development. Strong problem-solving, analytical, and communication skills. #LI-JJ1
