Infrastructure Engineer – AI Training

xAI is building Grok and the underlying infrastructure to train frontier AI models. We are hiring Infrastructure Engineers to work on the systems that power our massive GPU clusters — including distributed training, high-performance networking, storage systems, and Kubernetes orchestration at scale.

This is a highly technical role requiring deep knowledge of Linux systems, GPU workloads, and distributed systems. Experience with CUDA, Kubernetes, and large-scale ML training infrastructure preferred.
