Astro Mechanica is a vertically integrated aerospace company developing a scalable technology platform to power critical infrastructure, mission operations, and the future of flight. We apply aerospace engineering and quality standards across our products, delivering high performance, reliability, and efficiency for the most demanding operating environments. Astro Mechanica is backed by leading venture and strategic investors, including Andreessen Horowitz (a16z), Giant Step Capital, United Airlines Ventures, and Voyager Ventures.
Astro Mechanica is seeking a Mechanical Systems Engineer (Fluid Systems) to own the design, integration, and maturation of critical vehicle fluid systems. The ideal candidate is a hands-on engineer with a passion for owning complex systems from the ground up. You thrive in fast-paced development environments, are comfortable making informed tradeoffs, and take pride in building systems that are robust, maintainable, and performant across the full flight envelope. Your work will directly enable propulsion, actuation, thermal management, and vehicle operability at extreme conditions. You will own one or more subsystems end-to-end, leading them from early concept through detailed design, qualification, and flight test.

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.
