Job description
Advanced Reentry Technologies
Who We Are:
Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.
The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.
Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry. Position Overview
As a Senior 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.
