GNC Engineering Intern

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 GNC Team for the summer of 2027 (program begins on June 7, 2027 for semester schools and June 27, 2027 for quarter schools). You are a GNC-focused student who wants to make a real contribution to the guidance and control system of a clean-sheet autonomous aircraft. You are comfortable working from first principles, want to write simulation and flight code yourself, and are excited to work closely with hardware and software teams. As a summer 2027 intern, you’ll be embedded with the team in San Francisco, working on real projects alongside full-time engineers and learning from them. You care 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.
