About The Position

MTSI is seeking several experienced Software Developers to support the U.S. Navy’s Threat Engineering Program with advanced modeling, simulation, and analysis efforts for multi-domain sensors and weapon systems. Positions play a critical role in the development of Acquisition Threat Engineering Products (ATEP) and RedShip product line. Position requires ability to work in C++, Advanced Framework for Simulation, Integration, and Modeling (AFSIM), as well as Next Generation Threat System (NGTS) simulation environments used to evaluate enemy combatant ships, weapons, and sensor performance to support Navy mission objectives. As part of a multidisciplinary engineering team, the developers will contribute to the design, implementation, integration, and sustainment of complex software architectures that enable next‑generation test capabilities across the fleet.

Requirements

US Citizenship and a secret level clearance.
Bachelor’s degree in Aerospace Engineering, Computer Science, Computer Engineering, or a closely related technical field.
5+ years of experience developing multi-domain DoD modeling and simulation software.
Demonstrated experience developing, testing, or maintaining high‑fidelity models.
Strong proficiency in object-oriented principles.
Advanced hands‑on experience building, debugging, and testing C++ applications in a high‑performance environment.
Willingness to collaborate with project managers and technical leads to build roadmaps for product development.
Desire and ability to function in an Agile team environment.
Knowledge of DevSecOps methodologies and secure software development best practices.
Ability to develop and maintain detailed product documentation.
