Senior GNC Engineer (Reentry)

About this role

Turning Space into a Transportation Layer for Earth

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 Senior GNC Engineer at Inversion, you will report directly to the Senior Manager of Arc Vehicle Reentry. In this role, you will own the guidance, navigation, and control (GNC) algorithms that govern the hypersonic and supersonic phases of flight from reentry initiation down to main parachute deployment. You will design, model, and validate flight control laws, trajectory planning algorithms, and state estimation filters to safely maneuver through extreme aerothermal environments. Operating with high autonomy, you will build 6DOF simulation capabilities, evaluate control authority of flap actuators, and directly influence the vehicle's aerodynamic shape and trajectory architecture.
