Job description

Astra’s mission is to improve life on Earth from space by creating a healthier and more connected planet. Today, Astra offers one of the lowest cost-per-launch dedicated orbital launch services, and one of the industry’s leading flight-proven electric propulsion systems for satellites, the Astra Spacecraft Engine.

The Team

The Ground System Structures Team is a cross-functional group of engineers working to design and improve our ground support equipment. We develop the structures necessary to transport, erect, hold down, and release an orbital-class rocket. Our team touches all aspects of system design including concept development, detailed design, analysis, and drawings. The team is also responsible for the development of qualification test plans and supporting testing and launch operations.

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.

The Opportunity

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.

How You’ll Fulfill Your Mission

• Design mechanical and fluid systems using CAD (NX preferred)
• Create and maintain P&IDs and operational flow diagrams
• Define procedures for startup, shutdown, and emergency operations
• Perform structural analysis for sizing and validation
• Support system build, integration, and field testing
• Collaborate with propulsion, avionics, and operations teams
• Improve system performance and maintainability over time

Why We Value You:

• 2+ years’ experience in mechanical/structural design
• You are experienced with a variety of structural design processes including fabrication, and post weld heat treatment and machining
• You can analyze welded joints using hand‑calcs and FEA per AWS or equivalent standard
• You are experienced with bolted joint design
• You are experienced with CAD and PLM software tools, particularly with large, shared assemblies
• You own projects from beginning to end, with little oversight
• You’re excited to work in a fast‑paced, self‑driven, iterative startup environment, and to build the systems that enable daily launches to space

Desired Multipliers

• Cryogenic or high-pressure system design
• Familiarity with ASME B31.3, AWS D10.18, or similar codes
• Experience operating or supporting field-deployed systems
• Knowledge of aerospace or launch safety standards
• Experience in aerospace or space startup environments preferred
• Experience with release mechanisms and actuators

The pay range for this role is: $100,000 - $130,000 per year

The stated compensation range reflects only the targeted base salary range in the _ San Francisco Bay Area _ and excludes additional earnings such as bonus and benefits. If your salary requirements fall outside of the range, we still encourage you to apply.
