Thermal Engineer, Thermal Protection Systems (TPS)

Job description

Job responsibilities

• Own TPS design, material selection, and thermal analysis for hypersonic and high-speed flight vehicles, including missiles, reentry systems, and advanced flight platforms.
• Perform aerothermal heating analysis using engineering correlations, boundary-layer methods, and CFD to define the thermal environment across flight trajectories.
• Conduct ablation and material response modeling to predict TPS recession, in-depth thermal response, and structural thermal margins under mission-representative conditions.
• Evaluate and select TPS materials, including carbon phenolic, PICA, silicone-based ablators, ceramics, and high-temperature composites, based on aerothermal loads, mass constraints, and manufacturability.
• Partner with aerodynamics, structures, propulsion, and systems engineers to integrate TPS into vehicle design while managing mass, volume, and performance tradeoffs.
• Define and execute thermal and material characterization tests, including arcjet testing, furnace testing, and instrumented flight-article thermal testing.
• Build and maintain thermal models spanning hand calculations through detailed FEA/CFD to predict system performance, establish design limits, and support qualification.
• Present TPS status, risks, tradeoffs, and recommendations in internal design reviews and customer-facing technical reviews.

Job requirements

• MS or PhD in Aerospace Engineering, Mechanical Engineering, Applied Physics, or a related field with a focus on aerothermodynamics, heat transfer, thermal sciences, or materials science.
• 2+ years of experience in TPS design, aerothermal analysis, or high-temperature material response for aerospace or defense systems.
• Strong first-principles understanding of aerodynamic heating, ablation, high-temperature heat transfer, and material thermal response.
• Experience with material response modeling tools such as FIAT, CMA, TITAN, or equivalent ablation/thermal response codes.
• Experience supporting thermal design for hypersonic vehicles, reentry systems, missiles, rocket nozzles, or other systems operating in extreme aerothermal environments.
• Ability to obtain and maintain a U.S. Top Secret security clearance.
• Experience with aerothermal CFD tools such as DPLR, US3D, Loci-CHEM, CFD++, ANSYS Fluent, or STAR-CCM+ for high-speed reacting flow analysis.
• Experience with arcjet testing, thermal characterization testing, or flight-article thermal instrumentation.
