## About the role

As a Lead Propulsion Component Engineer you will own the development of flight-critical propulsion components—including valves, actuators, and high-performance mechanical systems operating in extreme thermal and pressure environments. This is a player–coach role: you will directly design and deliver hardware while leading a small team of engineers. You will own components from clean-sheet design through test, qualification, and flight, and your hardware will move quickly from concept to real-world operation.

## What they're looking for

- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or related field
- 7+ years of experience developing mechanical or propulsion hardware
- Demonstrated experience owning hardware from concept through test or production
- Strong fundamentals in fluids, thermodynamics, mechanics, and materials
- Hands-on experience with design, build, and integration of mechanical systems
- Willingness to work hands-on in build, integration, and test environments
