Who 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.

Who We Are:

Eras of humanity can often be defined by a dominant transportation mode - horse drawn chariots, ocean going boats, or aircraft. These were spurred by a small group of people rigorously focused on building technology to achieve faster access to more of the world.  We seek to usher in a new era of humanity defined by universal access to the whole globe free of borders and the presence of a routine way from space to Earth. To do this, we are building highly maneuverable re-entry vehicles that can loiter in orbit before precision landing back on Earth.

• Write software as needed (e.g.: embedded software for micros, test scripts, etc.)
• Contribute to the design and development of a simulation system capable of automatically provisioning and deploying resources to support simulation workflows

Required Qualifications

• 5+ years of professional experience in electronics integration, development, and testing
• Experience with custom wiring harness design and assembly, including connector selection, pin mapping, wire sizing, and shielding strategies for EMI/EMC
