Job description

MTSI is seeking Senior 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.
• 7+ 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.
