About The Position

JHNA, CTSi, and EXPANSIA have come together to form a Defense Technology platform named Aether Aerospace focused on delivering high-impact technologies, technology-enabled services and advanced manufacturing solutions to the U.S. Department of Defense and related national security customers. Backed by Falfurrias Management Partners, the platform brings together deep domain expertise across Army, Navy, and Air Force and Space Force programs, digital engineering, systems integration, and specialized manufacturing capabilities. The combined organization operates as a multi-entity aerospace and defense technology and tech-enabled services and manufacturing enterprise positioned for scalable growth, operational excellence, and long-term value creation. We are seeking a Modeling and Simulation Engineer/Scientist III to support U.S. Air Force programs in Dayton, Ohio. In this role, you will develop and integrate high-fidelity models using the Advanced Framework for Simulation, Integration, and Modeling (AFSIM) to evaluate air and space systems, electronic warfare (EW) capabilities, and mission-level performance. Responsibilities include creating radio-frequency (RF) sensor and antenna models, building algorithms and simulation components, and integrating these elements into engagement- and theater-level AFSIM scenarios. You will work closely with Air Force stakeholders to support analysis, concept development, and acquisition decisions through physics-based modeling, scenario development, and Monte Carlo simulation execution.
