From the original posting

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, AI SATELLITES (STARMIND)

SpaceX is leveraging its experience deploying and operating the world’s largest satellite constellation to develop Starmind, a new constellation of satellites capturing solar energy in space to power low-cost, high-performance AI compute for Earth. Realizing this vision demands highly reliable, high performance electrical hardware ranging from power electronics, high speed digital systems, mixed signal designs, robust avionics, networking, and custom compute electronics. These systems must operate in the extreme environment of space while delivering the connectivity, control, power distribution, and processing needed for orbital AI inference.

Our Power Electronics team designs and develops the power conversion and control systems at the heart of Starmind satellites and orbital data centers — enabling the reliable, high-efficiency power delivery required for massive on-orbit AI compute. As a senior member of the team, your designs will run the gamut from low voltage to kV range, and powers from 1W to many kW (applications include high-density compute power delivery, battery systems, motors/actuators, ion propulsion, laser optical links, and other vehicle systems critical to orbital AI platforms).

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
5+ years of experience in power converter development
Previous experience with DC-DC power converter development
Previous experience working with magnetics and design of custom transformers and inductors, including planar magnetics
Experience in modeling, simulation, and testing of power electronics

PREFERRED SKILLS AND EXPERIENCE:

Master’s degree in electrical engineering or related field
7+ years of experience in power converter development
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
Familiarity with power supply testing and packaging for harsh environments
Experience with in-lab impedance measurement and loop-gain measurement
Familiarity with spacecraft electrical power systems and knowledge of radiation effects
Familiarity with lithium-ion battery handling, safety, and usage

ADDITIONAL REQUIREMENTS:

This position is 100% onsite and requires relocation to the Austin-Bastrop area if not already local – remote or hybrid work not considered
Ability to work extended hours or weekends as needed for mission critical deadlines
Some travel may occasionally be required
