Site Reliability Engineer

Direct message the job poster from Hamilton Barnes 🌳

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, you’ll own the reliability, performance, and automation of this GPU-powered infrastructure, ensuring seamless orchestration across environments managed by Slurm, Kubernetes, or direct SSH access. You will support their exciting new products coming to the market and help shape 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.

• 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.

• Customer-facing experience with a proactive, versatile “Swiss army knife” attitude.
• Strong hands-on experience with Kubernetes and Slurm for cluster orchestration and workload management.
• Deep knowledge of Linux systems, networking, and GPU infrastructure (NVIDIA H100/H200/B200 preferred).
• Proficiency in Python, Go, or Bash for automation, tooling, and performance tuning.
• Experience with observability stacks (Prometheus, Grafana, Loki) and incident response frameworks.
• Familiarity with high-performance computing (HPC) or AI/ML training infrastructure at scale.
• Background in reliability engineering, distributed systems, or hardware acceleration environments is a strong plus.
