Senior Combustion Devices 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 are a Senior Propulsion Engineer experienced in designing the combustion devices within propulsion systems. You come from a background working in ground power, aviation, automotive, or rocketry. You approach your work from a robust set of first principles which enable you to work methodically through challenging technical problems with feedback from test verification.
