The Role</strong></h1> <p data-pm-slice="1 1 []">Mach Industries is seeking a Senior Aerospace Engineer, Aerothermal & Hypersonics to own high-speed aerodynamic and aerothermal design for next-generation hypersonic and atmospheric entry systems. This role is for an engineer with 5–7+ years of experience who has taken complex aerospace work from concept through design, analysis, test, and implementation — and who can help stand up aerothermal and TPS test capability as the company scales.</p> <p>You will lead hypersonic vehicle shaping and aero/aerothermal trades, predict aerodynamic heating and related high-temperature flight environments, and contribute to Thermal Protection System (TPS) / heat-shield evaluation in partnership with materials, structures, and Thermal Engineers. You will also support lower-speed aero work in conjunction with other aerodynamicists when programs require it.</p> <h1><strong>Key

Responsibilities</strong></h1> <ul data-pm-slice="3 3 []"> <li> <p>High-speed aero and aerothermal design: Lead or co-own aerodynamic and aerothermal design activities for hypersonic and atmospheric entry vehicles — vehicle shaping, performance, stability, and thermal environment definition — and support lower-speed aero work in conjunction with other aerodynamicists when the program requires it.</p> </li> <li> <p>Aerothermal environments: Predict and analyze aerodynamic heating environments (convective and radiative where relevant), including engineering (first-order / closed-form) heating methods and higher-fidelity aerothermal analysis as needed to support vehicle, TPS, and structural design.</p> </li> <li> <p>TPS / heat-shield contribution: Develop and evaluate Thermal Protection System concepts, materials, architectures, and margins for hypersonic flight and atmospheric entry vehicles — including material selection support and thermal performance assessment — in close partnership with materials and structures.</p> </li> <li> <p>Trajectory-coupled environments: Perform or closely support entry, descent, and re-entry (and hypersonic mission) trajectory-informed aerothermal environment prediction and vehicle performance assessments.</p> </li> <li> <p>Multidisciplinary integration: Partner with structures, Thermal Engineers, propulsion, GNC, and systems engineering to close vehicle-level trades among aero, heating, TPS mass/thickness, and mission performance.</p> </li> <li> <p>Analysis, trades, and documentation: Build and maintain engineering models, run trade studies, and document assumptions, margins, and recommendations for design reviews across the product lifecycle.</p> </li> <li> <p>Test and validation (stand-up + execute): Help establish and then support ground aerothermal/TPS test approaches and flight-test planning, execution, data analysis, and post-flight validation — including correlation of predicted environments and TPS performance to test evidence.</p> </li> </ul> <h1><strong>Required
