Senior GNC Engineer

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.

What You’ll Do:

As a GNC Engineer at Inversion, you will have an instrumental impact on the functionality and performance of our next-generation reentry vehicles. You will own a substantial aspect of the Guidance, Navigation, and Control that will enable the accurate and precise landing of our Arc spacecraft. Aspects of this work include developing novel algorithms for the final landing stages of flight, building the modeling and simulation needed to quickly iterate on those algorithms, and rapidly flight testing them to achieve the required performance. This is a unique opportunity to work on the early stages of a novel reentry vehicle, including defining vehicle architecture and creatively solving new design challenges. Your impact will be on all aspects of the Guidance, Navigation, and Control that powers the world’s first reentry vehicle designed for turning space into a transportation layer for Earth. You will be a key member of the Accurate Landing team, reporting directly to the Director of Engineering, Accurate Landing.

Required Qualifications:
