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 Red Ship 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.


Key Responsibilities Design, develop, and optimize C++, NGTS, or AFSIM modeling and simulation software for multi‑domain, high-threat combat environments.

Implement object‑oriented architectures that accurately represent  surface ships, missiles, and sensor system behavior.

Collaborate closely with project managers, system engineers, and technical leads to define technical roadmaps, development milestones, and long‑term product strategies.

Participate actively in Agile development workflows, including sprint planning, peer reviews, and iterative release cycles.

Apply Dev Sec Ops  principles to ensure secure, maintainable, and scalable development and deployment practices.

Develop, update, and maintain comprehensive technical documentation, including system specifications, design artifacts, test plans, and user manuals.

Support verification and validation activities to ensure model accuracy and performance fidelity.

Integrate simulation components into larger system‑of‑systems environments and perform troubleshooting and performance tuning as needed.

Required Qualifications:

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 Dev Sec Ops  methodologies and secure software development best practices.

Ability to develop and maintain detailed product documentation.

Desired

Qualifications:

Ability to obtain Top Secret clearance Prior experience developing platform, weapon or combat system models, including kinetic and non‑kinetic engagements.

Familiarity with weapon systems, radars, or navy combat systems.

Intermediate proficiency with Python and MATLAB for data analysis, prototyping, or model validation.

Master’s degree in a technical field (e.g., Computer Science, Electrical Engineering, Aerospace Engineering).#LI-JJ1
