Company Description
CambridgeNexus is an AI-native compute infrastructure company specializing in GPU-powered data centers. Our high-density, low-latency infrastructure is engineered to support modern machine learning, large-scale model training, and inference.
Role Description
Responsibilities include designing, monitoring, and maintaining high-performance GPU data center infrastructure. You will oversee troubleshooting of GPU systems, enhance network efficiency, implement network security solutions, and ensure the reliability and scalability of deployed systems.
What You’ll Own
GPU cluster deployment (GB300, NVLink, InfiniBand).
Power & cooling optimization (150kW+/rack).
Incident response & root-cause analysis.
Capacity planning and expansion.
Requirements
8+ years in data center / HPC / GPU infrastructure.
Hands-on with NVIDIA stack (CUDA, drivers, fabric). * Obsessed with reliability and performance
