Job description

MTSI is seeking a skilled AFSIM (Advanced Framework for Simulation, Integration, and Modeling) Developer/Analyst to design, implement, and analyze mission-level simulations supporting advanced DoD systems and CONOPS development. The ideal candidate will have hands‑on experience extending AFSIM through scenario scripting, high‑fidelity subsystem modeling, analytic workflows, and C++ plugin development. This role involves building and integrating complex models for sensors, weapons, communications, and decision logic into scalable simulation architectures to evaluate system performance and mission effectiveness.

Key Responsibilities

• Architect, develop, and maintain AFSIM models, plugins, and simulation components to support advanced mission‑level analyses.
• Develop custom AFSIM behaviors, algorithms, and decision models (tasking logic, autonomy, federated multi‑domain behaviors, etc.).
• Integrate external data sources (threat models, performance data, signatures, environmental models) to improve simulation fidelity.
• Analyze simulation results and extract actionable insights and recommendations to stakeholders.
• Collaborate with engineers, analysts, and subject matter experts to define simulation requirements and scenarios.
• Integrate new capabilities, algorithms, and data into AFSIM models to enhance simulation fidelity.
• Document simulation processes, methodologies, and results in technical reports and presentations.
• Support briefings and discussions with customers and stakeholders.

Basic Qualifications

• US citizenship and ability to obtain and maintain a security clearance (if not already held)
• Bachelor’s degree in engineering, Computer Science, Mathematics, Physics, or related field.
• 3+ years hands‑on experience developing AFSIM models, scenarios, and plugins.
• Familiarity with modeling and simulation principles including discrete‑event simulation, stochastic modeling, Monte Carlo techniques, and scenario‑based experimentation.
• Strong programming skills in languages such as C++, Python, or similar.
• Excellent problem‑solving and analytical skills.
• Strong written and verbal communication skills.

Preferred Qualifications

• Master’s degree in a technical field.
• Experience modeling military platforms, RF systems, weapons, C2 networks, orbital mechanics, or EW effects.
• Familiarity with other simulation tools or frameworks (e.g., MATLAB, STK, or similar).
• Knowledge of data visualization and analysis tools.

Why Join Us?

• Work on cutting‑edge technologies and contribute to mission‑critical projects.
• Join a collaborative, high‑performing team of engineers and analysts.
• Competitive compensation and benefits package.
