Modeling & Simulation Engineer, Missiles

The role

You will develop, integrate, and validate dynamic and closed-loop simulations for guided weapons and flight vehicles. This includes working with trajectory models, 3-DOF and 6-DOF simulations, and hardware-in-the-loop test systems.

What you will do

• Develop, integrate, and maintain 3-DOF and 6-DOF flight and engagement simulations.
• Implement and validate equations of motion, coordinate-frame transformations, and rigid-body dynamics.
• Develop or integrate models of aerodynamics, propulsion, mass properties, and navigation sensors.
• Integrate guidance algorithms, navigation functions, and autopilots into closed-loop simulations.
• Evaluate trajectory and engagement performance.
• Develop error budgets and perform Monte Carlo analysis.
• Support system-design trades involving vehicle configuration and sensor selection.
• Translate system and subsystem requirements into model requirements and simulation cases.
• Integrate models and software into desktop, SIL, SITL, HITL, HWIL, and real-time environments.
• Support hardware and software integration laboratories.

Required qualifications

• Bachelor’s degree in aerospace engineering, mechanical engineering, electrical engineering, computer engineering, computer science, physics, applied mathematics, or a related technical discipline, or
• Relevant experience in missile or flight-vehicle modeling and simulation, flight dynamics, GNC, trajectory analysis, weapon-system performance, or a closely related field.
• Hands-on experience developing, integrating, or using 3-DOF or 6-DOF dynamic simulations.
• Strong fundamentals in flight mechanics, rigid-body dynamics, coordinate systems and transformations, numerical integration, control or estimation concepts, and dynamic-system analysis.
• Demonstrated depth in at least one relevant missile modeling area.
• Strong programming ability in at least one scientific or analytical environment such as MATLAB, Python, or C++.
• Experience performing Monte Carlo analysis, error-budget analysis, sensitivity analysis, robustness analysis, uncertainty quantification, or design of experiments.
• Experience validating or correlating dynamic models against authoritative sources.
• Experience working with system requirements, subsystem interfaces, test objectives, verification methods, and performance criteria.
• Experience with Git, code review, automated testing, issue tracking, continuous integration, and reproducible software or analysis workflows.
• Ability to work independently, make sound technical judgments, document assumptions and limitations clearly, and collaborate across engineering disciplines.
• Active Secret clearance.

Nice to have

• Master’s degree or higher in aerospace engineering, mechanical engineering, electrical engineering, applied mathematics, or a related field.
• Experience with tactical missiles, strategic missiles, ballistic systems, interceptors, cruise missiles, air-launched weapons, ground-launched weapons, hypersonic vehicles, launch vehicles, or other a
• Experience designing, tuning, or evaluating guidance laws, autopilots, control laws, state estimators, Kalman filters, or multisensor navigation systems.
• Experience with classical, modern, robust, optimal, adaptive, or nonlinear control methods.
• Experience with trajectory optimization, optimal control, multidisciplinary design optimization, launch-zone analysis, intercept analysis, or engageability analysis.
• Experience creating or integrating aerodynamic databases, propulsion models, boost-phase models, thrust-vector-control models, staging or separation models, and mass-property models.
• Experience integrating RF, EO/IR, multimode, passive, or other seeker and target-tracking models.
• Experience with fire-control, weapon-target assignment, target-state estimation, fuzing, lethality, or endgame-performance models.
• Experience integrating embedded flight software, tactical software, auto-generated code, or processor-representative software into closed-loop simulations.
• Experience supporting flight-test planning, range operations, telemetry analysis, preflight prediction, postflight reconstruction, or flight-anomaly resolution.
