Sr. Power Electronics Engineer - Traveling Wave Tube Amplifier (Starlink)

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 and provides fast, reliable internet to 9M+ 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.

SpaceX Gateways are responsible for delivering internet from the ground to the satellites – they must be cost effective, capable of high performance in all weather conditions, and reliable over long periods of time. The traveling wave tube amplifier (TWTA) team is revolutionizing RF vacuum electronics to power the future of space communications with SpaceX gateways by building hardware an order of magnitude faster than traditional industry and an order of magnitude more cost-effective. In addition, we're developing our own high-voltage power supplies to drive unparalleled performance in these high-frequency, high-bandwidth amplification systems critical to our mission.

As a key player on this team, you'll lead the design of sophisticated kV-level power supplies that drive TWTA systems. From concept to deployment, you'll own the full hardware lifecycle—prototyping, testing, integration, and iteration—while collaborating closely with experts across RF engineering, mechanical design, systems integration, manufacturing, and more. If you're passionate about pushing the boundaries of power electronics and want to contribute to humanity's multi-planetary future, this is your chance to make a tangible impact.
