Sr. Power Electronics Engineer, AI Satellites (Starmind)

SpaceX • Bastrop, TX

5h • Onsite

About The Position

SpaceX is developing Starmind, a satellite constellation that captures solar energy in space to power low-cost, high-performance AI compute for Earth. The Power Electronics team designs and develops the power conversion and control systems for Starmind satellites and orbital data centers, enabling reliable, high-efficiency power delivery for large-scale on-orbit AI compute. The role covers designs ranging from low voltage to the kilovolt range and from 1 W to many kilowatts, with applications including compute power delivery, battery systems, motors and actuators, ion propulsion, laser optical links, and other vehicle systems.

As a senior member of the team, you will design, analyze, and test DC-DC power converters for harsh environments; contribute to electrical power system and subsystem design trades and requirements; define and perform verification testing and analysis; and collaborate with design, test, and production engineers to develop power electronics hardware. The role is 100% onsite in the Austin-Bastrop area. Remote and hybrid work are not considered. Extended hours or weekends may be needed for mission-critical deadlines, and occasional travel may be required.

Applicants must meet U.S. export-control eligibility requirements: be a U.S. citizen or national, lawful permanent resident, refugee, or asylee, or be eligible to obtain the required U.S. Department of State authorizations.

Requirements

• Bachelor’s degree in electrical engineering.
• At least 5 years of experience in power converter development.
• Previous experience developing DC-DC power converters.
• Experience working with magnetics and designing custom transformers and inductors, including planar magnetics.
• Experience modeling, simulating, and testing power electronics.
• Ability to work onsite in the Austin-Bastrop area; relocation is required if not already local.
• Ability to work extended hours or weekends as needed for mission-critical deadlines.
• Must meet the stated U.S. Government export-control eligibility requirements or be eligible to obtain the required authorizations.

Nice To Haves

• Master’s degree in electrical engineering or a related field.
• At least 7 years of experience in power converter development.
• Strong grasp of analog control and discrete logic design.
• Working experience with voltage-mode and current-mode control and compensation design.
• Experience with AC-DC converters and power factor correction.
• Strong grasp of DC-DC topologies and ability to select suitable architectures and components.
• Understanding of fault-tolerant and reliability-focused design.
• Familiarity with failure mode effects and criticality analysis.
• Familiarity with wire-wound and planar inductor and transformer design.
• Familiarity with power supply testing and packaging for harsh environments.
• Experience with in-lab impedance and loop-gain measurement.
• Familiarity with spacecraft electrical power systems and knowledge of radiation effects.
• Familiarity with lithium-ion battery handling, safety, and use.

Responsibilities

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