What you'll do
- Own the reliability, performance, and observability of the entire inference stack
- Design and refine telemetry pipelines — metrics, logs, and traces that turn hundreds of terabytes of signal into clear, actionable insight
- Tune Kubernetes autoscalers to squeeze more efficiency out of GPUs
- Craft Terraform modules that bake resilience into every new cluster
- Harden request-routing and retry logic so even transient failures go unnoticed by users
- Rely on automation and runbooks to detect, isolate, and remediate problems in minutes when incidents arise
- Drive the post-mortem culture that prevents recurrence
- Scale the platform smoothly while hitting aggressive cost and reliability targets
- Collaborate with software engineers to turn reliability into a feature users never have to think about
What we're looking for
- Deep fluency with Kubernetes, Prometheus, Grafana, Terraform, and the craft of infrastructure-as-code
- Script comfortably in Python or Bash
- Understand the nuances of alert design and SLOs for high-throughput APIs
- Enough time in production to know how distributed back-ends fail in the real world
- Care about building self-healing systems
- Thrive on debugging performance from kernel to application layer
Nice to have
- Experience shepherding GPU-heavy workloads — whether with vLLM, Triton, Ray, or another accelerator stack
- Background in MLOps or model-hosting platforms
