Senior Network / Domain Administrator & Security Operations (SOC)

Location: Playa Vista, California, United States

Department: Information Technology

Who We Are:

Eras of humanity can often be defined by a dominant transportation mode - horse drawn chariots, ocean going boats, or aircraft. These were spurred by a small group of people rigorously focused on building technology to achieve faster access to more of the world.  We seek to usher in a new era of humanity defined by universal access to the whole globe free of borders and the presence of a routine way from space to Earth. To do this, we are building highly maneuverable re-entry vehicles that can loiter in orbit before precision landing back on Earth.
