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.
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 seeking an intern to join our Propulsion Engineering Team for the summer of 2027 (program begins on June 7, 2027 for semester schools and June 27, 2027 for quarter schools). The ideal candidate is someone who wants to take ownership of real hardware, from concept through test, and is eager to understand how their work affects surrounding systems. You approach technical challenges from first principles. As an intern, you’ll be embedded with the propulsion team in San Francisco, working on real projects alongside full-time engineers, and your work will have a direct impact on the configuration and performance of the Duality™ engine.
In this role, your mission will be to help design, analyze, and validate propulsion hardware, with mentorship from senior engineers along the way. You’ll get hands-on experience across the full development cycle, from design trades to assembly to test, and you’ll learn to embody the test-like-you-fly philosophy.
At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role.
Astro Mechanica is an equal opportunity employer. We proudly recruit and hire a diverse workforce and are committed to creating an inclusive environment for all employees.

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.
