Simulation Engineer I, Arc Vehicle

About this role

<div class="content-intro"><p><strong>Turning Space into a Transportation Layer for Earth</strong></p></div><h3>Who We Are:</h3> <p>Inversion builds advanced reentry systems to deliver next-generation capabilities from space.<br>&nbsp;<br>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.<br>&nbsp;<br>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.<br>&nbsp;<br>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.</p> <p><strong><span data-contrast="auto"><span data-ccp-charstyle="Strong">What You'll Do</span></span></strong><span data-ccp-props="{"134233117":true,"134233118":true,"201341983":0,"335559740":240}">&nbsp;</span></p> <p><span data-contrast="auto"><span data-ccp-parastyle="Normal (Web)">As&nbsp;</span><span data-ccp-parastyle="Normal (Web)">a</span><span data-ccp-parastyle="Normal (Web)">&nbsp;</span></span><strong><span data-contrast="auto"><span data-ccp-charstyle="Strong">Simulation Engineer</span></span></strong><span data-contrast="auto"><span data-ccp-parastyle="Normal (Web)">&nbsp;at Inversion, you will focus on developing, automating, and maintaining the simulation and testing environments that validate our flight systems.
