Network Connectivity Engineer

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:

The Data Center Engineering team designs training and inference compute clusters from first principles, pushing thermal, electrical, and optical systems to the limit of physics. We operate as a highly cross disciplinary team comprised of mechanical, electrical, optical, and software engineers, all working to maximize the efficiency, reliability, and deployment speed of terrestrial compute to serve rapidly scaling demand.

As a Network Connectivity Engineer, you will design, deploy, and qualify large scale fiber optic networks for hundreds of thousands of coherently connected GPUs. You’ll architect systems for maximum bandwidth and minimum latency, collaborating with optical, mechanical, and software engineers to translate your designs into the largest coherent computing networks in the world.

RESPONSIBILITIES:

• Design and plan scalable, future-proof data center connectivity for clusters of hundreds of thousands of GPUs, including structured cabling plants that support evolving architectures and speeds beyond 800G.
• Procure fiber, copper, and other connectivity materials for new builds, expansions, and technology refreshes.
• Provide project management and construction oversight for connectivity scope on new data center builds and expansions.
• Plan and implement network upgrades and overhauls for technology refreshes in live data center environments.
• Develop Methods of Procedure (MOPs) and Standard Operating Procedures (SOPs) for connectivity deployments in live environments.
• Audit existing and new connectivity installations and hold vendors accountable for troubleshooting and repairs prior to network deployment turnover.
• Develop and maintain as-built documentation for all data center connectivity.
• Release and troubleshoot ISP circuits across multiple regions; interface with data center providers to drive circuit and cross-connect deployments.
