Stage Aerospace Engineering Jobs (NOW HIRING)

Mechanical Engineer - Design and Build Advanced Aerospace Hardware

Alameda, California | On-site

Opportunity Summary

Join a venture-backed aerospace startup developing an advanced launch platform that relies on robust mechanical systems operating in demanding environments. As a Mechanical Engineer, you will support the design, development, testing, and integration of hardware across multiple vehicle and launch platform subsystems, helping bring complex engineering concepts from initial design through validation. This is a highly hands-on engineering role with broad exposure across structures, high-pressure fluid systems, thermal protection, and integrated testing. You'll work closely with experienced engineers across multiple disciplines, contributing to hardware that is designed, built, tested, and continuously improved through rapid development cycles.
