Sr. Power Electronics Engineer, Satellites (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 of enabling human life on Mars.SR. POWER ELECTRONICS ENGINEER, STATELLITES (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 millions of 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 environmentsWork on electrical power system and sub-system level design trades and develop requirementsDefine and perform electrical power system verification testing and analysisWork with multidisciplinary teams of design, test, and production engineers to create new power electronics hardwareBASIC QUALIFICATIONS:Bachelor’s degree in electrical engineering5+ years of experience in power converter developmentPrevious experience with DC-DC power converter developmentPrevious experience working with magnetics and design of custom transformers and inductors, including planar magneticsExperience in modeling, simulation, and testing of power electronicsPREFERRED SKILLS AND EXPERIENCE:Master’s degree in electrical engineering or related fieldStrong grasp of analog control and discrete logic designExperience in modeling, simulation, and testing of power electronicsWorking experience in voltage and current mode control and compensation designExperience with AC-DC converters and power factor correctionStrong grasp of DC-DC topologies, with ability to select optimal architectures and componentsUnderstanding of design for fault tolerance and reliabilityFamiliar with failure mode effects and criticality analysisFamiliarity with design of wire wound and planar inductors and transformersFamiliarity with power supply testing and packaging for harsh environmentsExperience with in-lab impedance measurement and loop-gain measurementFamiliarity with spacecraft electrical power systems and knowledge of radiation effectsFamiliarity with solar arrays as input power sourcesFamiliarity with lithium-ion battery handling, safety, and usage ADDITIONAL REQUIREMENTS:Ability to work extended hours or weekends as needed for mission critical deadlinesCOMPENSATION AND BENEFITS:Pay range: Power Electronics Engineer/Senior: $135,000.00 - $205,000.00/per yearYour actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.Base salary is just one part of your total rewards package at SpaceX.
