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

The pay range for this position is $100,000 year to $130,000/year; however, base pay offered may vary depending on established government contract ranges, job-related knowledge, skills, and experience, and other factors. MTSI offers a full range of medical benefits, 401k, ESOP, paid time off, and other benefits, dependent on the position offered. Base pay information is based on market location.
