The RoleAs an
Aerothermal Analysis Engineer you will be the technical lead for predicting and managing the aerodynamic heating environments on the external surfaces of our new launch vehicle. This role will focus on predicting and characterizing the aerothermal environments experienced during ascent and re-entry, driving the boundary conditions that define the vehicle's external structures, including the main substrates and the required thermal protection system (TPS). This role can be located in
Seattle WA or at our HQ in San Carlos.Responsibilities- Environment Definition: Generate high-fidelity aerodynamic pressure and heating environments, for nominal and off-nominal conditions, for launch vehicle's ascent and re-entry trajectories using engineering-level tools and Computational Fluid Dynamics (CFD) codes.
- CFD Modeling & Simulation: Set up, execute, and post-process viscous, reacting-flow CFD simulations to characterize surface heating rates, pressure distributions, and boundary layer transition.
- TPS Sizing & Margin Management: Work closely with TPS and structures engineers to translate aeroheating predictions into material selection, sizing, and margin assessments.
- Aerothermal Database Management: Develop, maintain, and version-control the aeroheating database used across vehicle design cycles; define uncertainty bands and apply appropriate design factors.
- Test Planning & Correlation: Define ground-test requirements for arc-jet, wind-tunnel, and flight instrumentation; correlate analytical predictions to test data and update models accordingly.
- Cross-Disciplinary Collaboration: Coordinate with aerodynamics, structures, thermodynamics, propulsion, and systems engineering teams to ensure aeroheating constraints are properly captured in vehicle requirements and design.
- Documentation & Reporting: Author technical reports, design review packages, and analysis notes that clearly communicate aerothermal results, assumptions, and uncertainties to internal and external stakeholders.
Basic Qualifications- Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related field.
- 3+ years of experience in aeroheating analysis for launch vehicles, re-entry vehicles, or hypersonic systems.
- Proficiency with engineering-level aeroheating tools (e.g., MINIVER, UNLATCH, or equivalent).
- Experience with viscous CFD solvers applicable to high-speed, high-temperature flows (e.g., DPLR, LAURA, US3D, or equivalent).
- Strong understanding of hypersonic aerodynamics, boundary layer physics, and convective and radiative heat transfer.
- Demonstrated ability to develop and maintain aeroheating databases with defined uncertainties and design margins.
- Experience supporting design reviews and authoring technical documentation.
Preferred Qualifications- Master's or PhD in Aerospace Engineering, Mechanical Engineering, or a related discipline.
- 5+ years of experience performing aeroheating analyses for launch vehicles, re-entry vehicles, or hypersonic platforms, including flight-certified programs.
- Hands-on experience with arc-jet or high-enthalpy wind-tunnel testing and test-to-analysis correlation.
- Familiarity with radiative heat transfer in high-temperature shock layers and ablative TPS response modeling (e.g., FIAT, CHAR).
- Experience with Python or MATLAB scripting for automated post-processing of CFD and aeroheating databases.
- Strong analytical skills and ability to drive design decisions under uncertainty across multi-disciplinary teams.
