Sr. Power Electronics Engineer - High Voltage, Satellites (Starlink)

SpaceX•Redmond, WA

15h•$140,000 - $235,000

About The Position

SpaceX is developing Starlink, a broadband internet system that includes satellites, consumer receivers, and supporting software. SpaceX Gateways deliver internet from the ground to satellites, and the TWTA team develops RF vacuum electronics and high-voltage power supplies for gateway amplification systems. The Senior Power Electronics Engineer will lead the design of kilovolt-level power supplies for traveling wave tube amplifier (TWTA) systems. The role owns hardware across its lifecycle—from concept and prototyping through testing, integration, high-volume production, and ground station operation—and collaborates with RF, mechanical, systems integration, manufacturing, and other engineering teams. The engineer will design and verify DC-DC converters and power systems intended to operate reliably in harsh environments.

Requirements

Bachelor’s degree in electrical engineering, computer engineering, physics, or another STEM discipline.
At least 5 years of professional experience developing power converters, which may include professional work experience, project- or research-based student experience, or a combination.
Experience with magnetics and designing custom transformers and inductors, including planar magnetics.
Experience modeling, simulating, and testing power electronics.
Willingness to work extended hours and some weekends when needed for mission-critical deadlines.

Nice To Haves

Master’s degree in electrical engineering or a related field.
Demonstrated full-cycle ownership of a hardware project from concept to implementation.
Strong grasp of analog control and discrete logic design.
Working experience with voltage-mode and current-mode control and design.
Strong grasp of DC-DC topologies and the ability to select optimal architectures and components.
Understanding of design for fault tolerance and reliability.
Familiarity with failure mode effects and criticality analysis.
Practical in-lab impedance measurement and loop-gain measurement skills.
Self-motivation and strong organizational, written, and oral communication skills.

Responsibilities

Own hardware from conceptual design through high-volume production and ground station operation.
Design, analyze, and rigorously test DC-DC power converters for harsh environments.
Design power supplies that support tens of kilovolts and hundreds of watts.
Participate in electrical power system and subsystem design trades and shape requirements to optimize performance, efficiency, and reliability.
Lead definition and execution of verification testing and analysis for electrical power systems.
Collaborate with a multidisciplinary team to define power electronics hardware.
Iterate rapidly on designs, analysis, and testing to inform system trades and product direction.
Work with digital embedded devices, analog sensing and telemetry, and system controls.
Take ownership of product outcomes throughout development and production.
