## The role
Hop Aero is hiring an Aerothermal Engineer to own the aerothermal environment and heat-shield program at Hop Aero. This is a foundational technical role - this person will establish our internal capability from first-principles.
## What you will own
You will be the responsible engineer for all aerothermal, hypersonic, thermal protection systems, and re-entry matters.
- Develop coupled trajectory, aerodynamic and thermal analyses with the GNC and systems teams.
- Lead heat-shield architecture and material trades.
- Translate thermal predictions into vehicle requirements, interfaces, mass budgets and instrumentation needs.
- Plan and execute coupon, subscale and flight-like thermal testing.
- Develop internal high-enthalpy test capability.
- Support vehicle configuration trades related to aerothermodynamics.
- Establish analytical correlation and model-update processes using ground-test and flight data.
- Own aerothermal and TPS risks through design reviews and flight-readiness reviews.
## Requirements
- Demonstrated ability to execute in a similar role
- 5-10 years of relevant experience with hypersonic aerothermodynamics, atmospheric entry, high-temperature flows or other relevant thermal protection systems.
- Experience with aerodynamic heating, thermal analysis and relevant CFD or engineering analysis tools.
- Demonstrated ability to design and interpret thermal-material or high-enthalpy tests.
- Ability to work directly with structures, GNC, avionics, propulsion and test teams.
- Willingness to be highly hands-on in a small, fast-moving hardware organization.
## Nice-to-have
- Experience owning a reentry or hypersonic vehicle from cradle to grave.
- Experience with ablative TPS materials, joints, attachments and penetrations.
- Experience with arcjets, plasma torches, engine-plume rigs or other high-enthalpy test methods.
- Experience designing flight thermal instrumentation.
- Prior work at a fast-moving startup.
