At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. We are building artificial gravity space stations, allowing long-term stays in space without the adverse effects of zero-gravity. Our initial crewed space habitat will be Haven-1, scheduled to be the world’s first commercial space station when it launches into low earth orbit in May 2026. Our team is all-in, committed to executing our mission safely and on time. If you want to work with the most talented people on Earth furthering space exploration for humanity, come join us.
Vast is looking for an RF Test Engineer, reporting to the Director, RF Engineering, to develop and deploy creative test solutions for complex RF communications and antenna systems for artificial gravity space stations. Your work will be vital in the development and test of new and existing RF hardware to support Vast’s mission. This will be a full-time, exempt position located in our Long Beach location. Help us make the communication systems that will advance human spaceflight!
