Electrical Engineer in Southaven

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 making life multiplanetary and expanding consciousness to the stars. SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next. ABOUT THE ROLE: As a member of the facility operations team, you will design, build, and activate some of the world’s most technically advanced facilities and data centers. As an electrical engineer, you will design and build power systems that directly contribute to new infrastructure projects. You will be able to operate with autonomy to solve diverse and complex problems, excel at managing multiple projects simultaneously, and work in a dynamic, fast-paced environment. You will work with other MEP engineers, trade partners, and internal customers to support these goals and have the opportunity to drive real global impact, ultimately leading to making life multiplanetary.
