## Description

Mach Industries is seeking a New Graduate Vehicle Performance Engineer to support the analysis, design, and optimization of next-generation autonomous defense systems. Depending on your experience and interests, you may contribute to aerodynamics, aerothermal analysis, thermal systems, vehicle performance, trajectory analysis, or multidisciplinary design analysis and optimization (MDAO).

You will work alongside engineers across vehicle design, propulsion, structures, GNC, systems, and test to evaluate vehicle concepts, understand key performance drivers, and guide engineering decisions. This role is ideal for an analytically strong engineer who enjoys solving multidisciplinary problems and using modeling, simulation, and test data to improve real-world vehicle performance., * Analyze the aerodynamic, aerothermal, thermal, and mission-level performance of aircraft, missiles, and other autonomous defense platforms.

 * Develop analytical models and simulation tools to evaluate vehicle performance across operating conditions and mission profiles.
 * Perform aerodynamic and thermal analyses using computational, reduced-order, and first-principles methods.
 * Support vehicle sizing, configuration development, trajectory analysis, and multidisciplinary design trade studies.
 * Evaluate the effects of geometry, mass properties, propulsion, aerodynamics, thermal constraints, and control requirements on overall vehicle performance.
 * Build and improve MDAO frameworks that connect multiple engineering disciplines and accelerate design-space exploration.
 * Use Python, MATLAB, or similar tools to automate analyses, process data, and communicate technical results.
 * Support CFD, conjugate heat transfer, thermal network, or other physics-based modeling activities.
 * Correlate analytical and simulation results with wind-tunnel, ground-test, environmental-test, or flight-test data.
 * Collaborate with vehicle design, propulsion, structures, GNC, systems, software, manufacturing, and test teams.
 * Clearly communicate assumptions, technical risks, performance trades, and recommendations to the broader engineering team.
 * Develop tools, processes, and documentation that improve the speed and repeatability of vehicle analysis.
