POWER ELECTRONICS ENGINEER, SATELLITES (STARLINK)

SpaceX is leveraging its 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 is providing fast, reliable internet to 10M+ 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. As we continue to upgrade and expand the constellation, we’re looking for best-in-class engineers to join the team.

Our Power Electronics team designs and develops the power conversion and control systems at the heart of the Starlink satellites and portions of the ground systems - enabling the high-speed, low-latency broadband internet service provided by Starlink across the globe. As a member of the team, your designs will run the gamut from low voltage to kV range, and powers from 1W to many kW (other applications include solar/MPPT, battery, motors/actuators, ion propulsion, laser optical links, and other vehicle systems).

RESPONSIBILITIES:

• Provide engineering expertise in design, analysis, and testing of DC-DC power converters for harsh environments
• Work on electrical power system and sub-system level design trades and develop requirements
• Define and perform electrical power system verification testing and analysis
• Work with multidisciplinary teams of design, test, and production engineers to create new power electronics hardware

BASIC QUALIFICATIONS:

• Bachelor’s degree in electrical engineering, computer engineering, physics, or other STEM discipline 
• 1+ years of professional experience in power converter development 

PREFERRED SKILLS AND EXPERIENCE:

• Master’s degree in electrical engineering or related field
• Strong grasp of analog control and discrete logic design
• Experience in modeling, simulation, and testing of power electronics
• Working experience in voltage and current mode control and compensation design
• Experience with AC-DC converters and power factor correction
• Strong grasp of DC-DC topologies, with ability to select optimal architectures and components
• Understanding of design for fault tolerance and reliability
• Familiar with failure mode effects and criticality analysis
• Familiarity with design of wire wound and planar inductors and transformers
