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

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible with the ultimate goal ofenabling human life on Mars.

SR. POWER ELECTRONICS ENGINEER - TRAVELING WAVE TUBE AMPLIFIER (STARLINK)

At SpaceX were leveraging our experience in building rockets and spacecraft to deploy Starlink the worlds most advanced broadband internet system. Starlink is the worlds 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. Weve only begun to scratch the surface of Starlinks potential global impact and are looking for best-in-class engineers to help maximize Starlinks 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 addition were 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 youll lead the design of sophisticated kV-level power supplies that drive TWTA systems. From concept to deployment youll own the full hardware lifecycleprototyping testing integration and iterationwhile collaborating closely with experts across RF engineering mechanical design systems integration manufacturing and more. If youre passionate about pushing the boundaries of power electronics and want to contribute to humanitys multi-planetary future this is your chance to make a tangible impact.
