Senior GNC Engineer

GNC Engineer

Astro Mechanica is a vertically integrated aerospace company building a faster, more connected future. Our mission is to democratize high-speed flight by making supersonic travel flexible, accessible, and sustainable. We believe that rapid, on-demand, point-to-point global mobility will become the new standard for moving people and goods across the planet. To achieve this, we are integrating our advanced airframe and engine technologies—which include Duality™, our proprietary dual-use propulsion system—with a new flight operations model to make supersonic transport as efficient and economical as commercial air travel is today.

In the near term, we are developing adaptable, high-speed systems to close aircraft performance gaps for the United States government.

We're a team of passionate engineers dedicated to advancing aerospace. We're generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy.

You're a GNC engineer who wants real ownership over the guidance and control systems of a clean-sheet autonomous aircraft. You're comfortable working from first principles, collaborating tightly with propulsion, structures, and avionics, and making practical tradeoffs to get hardware flying. You care deeply about how systems behave in the real world—not just in simulation—and you're motivated by building control architectures that are robust, testable, and ready for flight.
