## About the role

The turbopump is the heart of the engine and sets its performance ceiling, and in this role, you will own pieces of it outright. You are the responsible engineer for the design definition, interfaces, fabrication, build, and test performance of your hardware — ore to orbit. As you trade different designs in the design space, you will own the case that your hardware meets its requirements and define what needs to be proven by analysis, what needs to be proven on the stand, and the plan that closes both.

## What they're looking for

- Bachelor’s degree in Aerospace, Mechanical, or related engineering field
- Proficiency in 3D CAD and in producing released, manufacturable design definitions with sound geometric dimensioning and tolerancing (GD&T), and tolerance stack-ups
- Working knowledge of turbomachinery fundamentals
- Hands-on experience with hardware from design through build and test
- Experience selecting materials and manufacturing processes for high-stress, high-cycle applications
- Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum
