Sr. RF Software Engineer, Customer Hardware (Starlink)

About the position

At SpaceX we're leveraging our experience in building rockets and spacecraft to deploy Starlink, the world's most advanced broadband internet system. Starlink is the world's largest satellite constellation that provides fast, reliable internet to 4M+ users worldwide. We design, build, test, and operate all parts of the system - thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We've only begun to scratch the surface of Starlink's potential global impact and are looking for best-in-class engineers to help maximize Starlink's utility for communities and businesses around the globe. As an RF software engineer on the Starlink team, you will work with a team of RF engineers, DSP engineers, software engineers, hardware engineers, and end users to design and build RF capabilities to deliver high-speed internet to those who need it most. Our customers currently include teachers in the most remote parts of the Amazon, researchers in Antarctica, digital nomads who travel via RV, emergency responders, commercial airlines, cruise lines, and residential users who live in more rural or developing areas. You will work in a highly collaborative and fast-paced environment, where we are exploring unsolved problems and applying the SpaceX mindset of iterating rapidly to go from design and demo to operational capability at a lightning pace.
