Aerothermal Engineer
About the role
Founding aerothermal engineer position responsible for predicting and surviving the reentry heating environment, owning aerothermodynamic analysis, sizing the thermal protection system, and defining aeroheating loads for all subsystems.
Responsibilities
- Run hypersonic and aerothermal CFD across the reentry trajectory (peak heating, integrated heat load, transition)
- Size and validate the thermal protection system against predicted heating environments
- Define aeroheating and aerodynamic loads that drive structures, GNC, and TPS design
- Build and maintain reentry simulation workflows
- Correlate models against flight, and ground test data
- Support trajectory and vehicle shape trades to manage the heating environment
Qualifications
- 3+ years in aerothermal, hypersonics, or reentry aerodynamics on flight or flight-relevant programs
- Hands-on hypersonic and/or aerothermal simulation experience
- Direct experience with reentry vehicles or high-speed atmospheric entry
- Proficiency with hyStrath, FUN3D, LAURA, or comparable hypersonic CFD tools
- Comfortable working across disciplines at an early-stage company
- Must be a US person. US export control (ITAR/EAR) requires this.

About Dispatch
Satellites for manufacturing in space
Dispatch is building refurbishable reentry vehicles that host and return payloads for companies making ultra-high-value materials (semiconductors, biotech, and pharma) that can only be manufactured in space. Right now, these companies have no practical way to manufacture and get their products back to Earth. We solve this bottleneck. We just returned from the Mojave Desert testing our first full-scale reentry heat shield designed to protect the satellite as it returns from space at Mach 20+, built in an apartment for 100x cheaper than competitors. To test, we held it behind a rocket engine to simulate the forces of atmospheric reentry. IT WORKED! Watch here - https://youtu.be/dhlQmnIoptg To scale, we anchor permanent infrastructure in orbit - building high power Autonomous Space Stations designed from day one for "lights-out" manufacturing serviced by the reentry vehicles.
