Job summary

SimTech, Inc. in Huntsville, AL, seeks a Mid-Level Modeling and Simulation Engineer to develop a high‑fidelity 6DOF flight simulation for a weapon system. You will build, validate, and extend models across flight dynamics, seeker, and guidance subsystems, and support SIL/HIL with flight software.

The role requires strong C/C++ proficiency, MATLAB and/or Python for analysis, and a solid foundation in GNC fundamentals. US citizenship with active Secret clearance is required.

Qualifications

• BS in Aerospace, Electrical, Mechanical or related engineering field.
• Demonstrated experience developing 6DOF or equivalent flight dynamics simulations.
• Proficiency in C/C++ for simulation development.
• Proficiency in MATLAB and/or Python for analysis, visualization, and automation.
• Working knowledge of GNC fundamentals: rigid body dynamics, coordinate frames, equations of motion, and control loops.

Responsibilities

• Model and analyze RF seeker performance, including sensor control, tracking, and target engagement behavior.
• Evaluate overall missile performance through airframe, propulsion, aerodynamics, and actuator dynamics modeling.
• Build post-processing and analysis tooling in MATLAB, Python, and related environments.
• Develop, extend, and maintain a closed loop 6DOF flight simulation written in C/C++.
• Develop and integrate subsystem models spanning flight dynamics, control actuation system, motor, gimbal, seeker, guidance, navigation, and control.
• Integrate and test flight software in the loop, supporting software-in-the-loop (SIL) and hardware-in-the-loop (HIL) configurations.
• Plan and execute trade studies, sensitivity sweeps, and Monte Carlo analyses to assess performance drivers and margins.
• Generate clear and concise technical results, briefings, and documentation for internal teams and external customers.
• Collaborate with GNC (guidance and control), seeker, propulsion, and software engineers to validate models against test and flight data.
