Site Reliability Engineer (Santa Rosa)

Senior Platform Engineer / Site Reliability Engineer AI Infrastructure

Join a stealth-mode startup building out their AI and cloud platform, powered by thousands of H100s, H200s, and B200s, ready to go for experimentation, full-scale model training, or inference. As a Platform Engineer / Senior Site Reliability Engineer, youll own the reliability, performance, and automation of this GPU-powered infrastructure, ensuring

seamless orchestration across environments managed by Slurm, Kubernetes, or direct SSH access. Aswell as supporting their extremely exciting new products coming to the market!

This is a rare opportunity to work at the intersection of AI infrastructure and AI, shaping the operational backbone of one of the largest GPU clusters in private deployment.

If you want to build and operate infrastructure for frontier AI workloads, automate systems at petascale, and be part of a founding engineering team, this is the place to do it.

Responsibilities

• Design, deploy, and maintain large-scale GPU clusters (H100 / H200 / B200) for training and inference workloads.
• Build automation pipelines for provisioning, scaling, and monitoring compute resources across Slurm and Kubernetes environments.
• Develop observability, alerting, and auto-healing systems for high-availability GPU workloads.
• Collaborate with ML, networking, and platform teams to optimise resource scheduling, GPU utilisation, and data flow.
• Implement infrastructure-as-code, CI / CD pipelines, and reliability standards across thousands of nodes.
• Diagnose performance bottlenecks and drive continuous improvements in reliability, latency, and throughput.
