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 a Senior Sensor Development Engineer to join our Avionics team and collaborate with the Environmental Control and Life Support Systems (ECLSS) team to support sensor development for human-rated space stations. You will lead sensor selection, procurement, and qualification, while supporting the growth of Vast’s internal sensor development program.
This will be a full-time, exempt position located in our Long Beach location.
