What the posting says

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.

OT NETWORK ENGINEER, PHYSICAL INFRASTRUCTURE

SpaceXSI is looking for an exceptional network engineer with experience in mission-critical or large-scale production environments to support our supercomputer infrastructure. As a member of the Physical Infrastructure Networking team, you will provide operational and designs services for physical infrastructure networks.
