About General Galactic
General Galactic designs, builds, and flies advanced spacecraft that redefine what’s possible beyond Earth. Led by former SpaceX, Varda, Impulse, and Relativity engineers, our vision is to dominate cislunar space and build the railway to Mars – expanding access to high-energy orbits and enabling the next generation of missions along the way. Based in Los Angeles, California, we’re leveraging our paradigm-shifting water-based technology to reshape the space domain for good.
Job Description
As a Mechanical Design Engineer (Electric Propulsion), you will work closely with a focused technical team to design and analyze critical electric propulsion hardware for our product suite, including Seldon and Dreadnought spacecraft vehicles, Genesis propulsion systems, and more.
