Sr Mechanical Engineer (2), Vehicle Structures Team

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 Opportunity 

The Vehicle Structures Team is a cross-functional group of engineers and technicians working to launch Astra's Rocket 4. The team develops the components, primary structures, sub-assemblies and complete stage integration to achieve orbital performance. Our team touches all aspects of system design including preliminary trade studies and system level definition as well as qualification and mission support.

How You'll Fulfill Your Mission

Design & Analysis

• Own components/sub-assemblies of our the vehicle to create design solutions from initial concept to detailed solid models and released drawing packages including documentation of assembly.
• Analyze components using FEA, CFD and hand calculations to inform mechanical, thermal, and pneumatic designs. Perform tolerance analyses to validate design robustness
• Create development, qualification and acceptance testing plans for your system and support execution.
• Collaborate with a cross-disciplinary team of system owners including electrical, mechanical, controls, and software engineers to support launch operations; conduct design reviews and implement feedback/obtain stakeholder buy-in and to verify and document cross-team requirements are satisfied.
• Challenge the existing assumptions and design choices, bring your own design experience and influences to our systems.
• Help define requirements and contribute to system-level engineering efforts

Development & Testing

• Lead hardware development through prototyping, environmental testing, and hot-fire campaigns
• Drive root cause investigations and implement corrective actions

Systems Integration

• Collaborate with propulsion, test, and structures teams to ensure seamless integration
• Deliver complete engineering documentation to support manufacturing and test operations

Why We Value You

• 5+ years of mechanical engineering experience across aerospace, automotive, defense, or similar high-reliability fields
• Proven track record in owning hardware from concept through test and production
• Proficient in CAD (NX, SolidWorks, etc.) and generating detailed drawings with GD&T
• Strong FEA fundamentals and experience in structural and thermal simulation
• Deep understanding of manufacturing processes including machining, welding, brazing, and heat treating
• Hands-on builder who’s comfortable wrenching, debugging, and working closely with technicians
• Humble, team-first mindset - you're comfortable with self-direction, but also take feedback well and step up wherever the team needs help
• B.S. in Mechanical, Aerospace, or related engineering discipline

Desired Multipliers 

• Experience designing and qualifying high-pressure (6000+ psi) or cryogenic fluid systems (LOX, RP-1, etc.)
• Background in complex mechanical mechanisms (e.g., Safe & Arm Devices, Arm/Fire Devices, actuators)
• Ownership of complete Tech Data Packages, compliance plans, and program reviews (PDR/CDR/TRR)
• Familiarity with ASME, NASA, or MIL standards and how to apply them in hardware design
• Startup or early-stage company experience, thriving in fast-paced, ambiguous environments
• Demonstrated ability to lead failure investigations and implement corrective actions
• Track record of mentoring engineers and leading multi-disciplinary efforts

The pay range for this role is: $118,864-$160,000
