Sr Fluids Engineer, Ground Systems

Astra • Alameda, CA

1d • $140,000 - $165,000

About The Position

The Ground Systems Fluids Team designs and builds fluid systems for propellant handling, propulsion support, and payload conditioning. We work across the full design cycle - from P&IDs and component selection to integration and testing - handling a range of fluids including cryogenics, high-pressure gases, and pyrophorics.

Our systems are modular and rapidly deployable, enabling global transport and fast assembly. By delivering flexible, reliable infrastructure, we help increase launch readiness and support Astra’s mission to enable more frequent and affordable space missions.

Join Astra’s Ground Systems team to design and build the systems that support rocket testing and launch operations. You’ll focus on mechanical and fluid systems - from propellant loading and environmental control to fire suppression and pad safety. This role combines hands-on hardware design with process definition to deliver reliable, mobile ground support equipment.
