Aurex is a mission-focused aerospace and defense company building the next frontier of deterrence. From hypersonics and missile defense to hardened networks and orbital systems, we design, test, and deliver the platforms that turn unproven ideas into battlefield-ready capability. Born in Huntsville and built for speed, Aurex brings together aerospace veterans, combat-tested operators, and forward-leaning technologists to solve problems that matter—fast.

We move from whiteboard to warfighter with precision, clarity, and zero tolerance for fluff.

We are seeking an engineer with approximately 3–8 years of relevant experience to support aerospace vehicle modeling, trajectory simulation, and hypersonics and missile defense analysis. This role combines model development with hands‑on analysis to evaluate vehicle performance, assess engagements, and answer engineering and mission questions.

• Develop and run trajectory simulations for missiles, hypersonic vehicles, spacecraft, and other aerospace systems.
• Develop, modify, validate, and maintain 3-DOF and 6-DOF vehicle models.
• Model vehicle dynamics, propulsion, aerodynamics, navigation, guidance, and control behavior using available vehicle data and engineering assumptions.
• Conduct hypersonics and missile defense analyses, including trajectory characterization, engagement performance, intercept opportunities, and system limitations.
• Plan and execute simulation runs, Monte Carlo analyses, sensitivity studies, and performance trade studies.
• Evaluate model outputs against expected system behavior, reference data, and established benchmarks.
• Analyze simulation results, identify trends, and explain their engineering and mission implications.
• Collaborate with software developers, analysts, and subject matter experts to integrate models and support simulation tool development.
• Document modeling approaches, assumptions, limitations, and technical findings, and present results to technical teams and customers.

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Physics, Mathematics, or a related technical field.
• Three or more years of relevant experience in aerospace vehicle modeling, trajectory simulation, GNC analysis, or related modeling and simulation work. This position is intended for candidates with approximately 3–8 years of experience.
• Experience conducting hypersonics and missile defense analysis using models, simulations, or engineering analysis tools.
• Working knowledge of missile defense systems and the roles of threats, sensors, interceptors, and fire control in an engagement.
• Experience programming in Python or C++.
• Experience developing or modifying aerospace vehicle models, trajectory simulations, or related analysis tools.
• Familiarity with Monte Carlo analysis, sensitivity studies, or performance trade studies.
• Experience using version control tools such as Git.
• Ability to translate vehicle data and engineering inputs into simulation models and interpret the resulting outputs.
• Strong analytical, problem‑solving, communication, and teamwork skills.
• Active Secret or higher security clearance.
• Ability to work on‑site at an Aurex office in Huntsville, AL.

• Master’s degree in Aerospace Engineering or a related technical field.
• Experience developing or validating 3-DOF or 6-DOF simulations.
• Experience developing guidance algorithms, control loops, or related…
