Network Connectivity Engineer at xAI · LumiJobs

Responsibilities

The Data Center Engineering team provides capacity and critical infrastructure that supports the functionality, growth, and reliability of SpaceXAI's training and inference platform. The team plans, designs, and constructs new data centers, capacity expansions, and technology refreshes in existing regions, and manages operation of the existing fleet to ensure system reliability and efficiency. The team includes electrical, mechanical, and connectivity engineers and operational managers with cross-disciplinary experience. We strive for timely delivery of efficient data centers that support the latest technologies and hardware architectures while maintaining uptime. As a Network Connectivity Engineer you will design large cable plants and low-voltage systems for the latest network architectures at scale (24 MW–100 MW+). You will ensure scalability while future-proofing data center cabling plants for changes in network architectures and data transmission speeds beyond 800G. You will work collaboratively and cross-functionally with capacity planning, network engineering, hardware reliability, construction, and operations.
Design and plan scalable, future-proof data center connectivity for network clusters greater than 40 MW, 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.
Collaborate with capacity planning, network engineering, hardware reliability, and construction teams on cluster design and delivery.
Apply knowledge of applicable building codes and industry standards to connectivity design and installation.
