Key skills for this role
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.
