Senior Fluid Systems 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.

Astro Mechanica is looking for a Senior Fluid Systems Engineer to join our growing team. The ideal candidate is someone who has a deep-seated understanding of complex system dynamics, and can take full ownership of modeling the thermal/fluid network of a novel engine architecture. Your work at Astro Mechanica will have a direct impact on the configuration and performance of the turboelectric adaptive jet engine.

In this role, your mission will be to architect, analyze, build, and test critical fluid systems for the propulsion systems. You will collaborate between propulsion, aircraft, and test teams to deliver optimized fluid hardware for the flight vehicle, proven through rigorous ground testing. You are attentive to detail and enjoy solving nuanced, interconnected problems.
