Structures Engineer II

Turning Space into a Transportation Layer for EarthWho We Are: Inversion builds advanced reentry systems to deliver next-generation capabilities from space. Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach. Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds. Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics. What You'll Do  As a Structures Engineer II at Inversion, you will own cradle to grave development of primary and secondary structures on one of the most capable reentry vehicles ever developed. You’ll drive primary structure design for a novel reentry vehicle working closely with cross-functional teams to solve complex packaging and manufacturability problems while driving designs toward real hardware.  This is a unique opportunity to own primary structure design of a new aerospace vehicle from initial concept through qualification and production. You will be a key member of the Mechanical team, reporting to the Director of Mechanical.  Key Responsibilities  Lead the design and development of primary and secondary vehicle structures, including load paths, joints, attachments, and structural interfaces  Own structural concept development from early architecture through hardware realization, balancing mass efficiency, robustness, manufacturability, and reliability  Partner closely with analysis engineers to develop and refine structural sizing approaches, margin strategy, and environmental load assumptions  Drive structural integration across vehicle subsystems, including payload, avionics packaging, propulsion interfaces, and deployment/separation systems  Support development of TPS-to-structure integration concepts, including attachment approaches, tolerances, and assembly considerations  Generate and review CAD, drawings, and product definition needed to release high-quality hardware  Support prototype and flight hardware builds through manufacturing coordination, assembly planning, test support, and failure investigation  Conduct trade studies and make sound engineering decisions in a fast-paced...
