xAI wants infrastructure engineers to help scale its supercomputing stack—and they're not playing small. They're after folks who know Kubernetes, can wrangle L4/L7 proxies, and speak fluent cloud networking.

The goal: push multi-cluster production inference across the Memphis supercluster (yeah, the one they spun up in just 120 days).

Bigger picture: xAI looks locked in on vertical integration, dialing in its infrastructure to run proprietary models fast and at serious scale.
