GNC Engineer III (Reentry)

Inversion
Los Angeles, CA Full Time
POSTED ON 1/4/2026
AVAILABLE BEFORE 2/17/2026
Turning Space into a Transportation Layer for Earth

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.

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 dynamic and precise reentry of our Arc spacecraft into the atmosphere. Aspects of this work will include development of the 6-DOF Monte-Carlo testing framework for reentry vehicles, subsystem testing to mature physics models, flight software deployment and integrated system testing and flight test support. Your work will help shape a novel reentry vehicle and inform how we architect it's missions. You will be challenged with problems that you haven't faced before and you will need to rapidly iterate and test the solutions that you develop. You will be a key member of the Reentry team, reporting directly to the Director of Engineering, Reentry.
