Customer Reliability Engineer

Own reliability, SLAs, and escalations for customer AI/HPC workloads at massive scale. Debug full-stack issues (hardware to scheduler), deliver technical customer incident communications, and drive root-cause fixes with internal engineering teams.

About the job

Role Scope

  • Own reliability for named customer workloads: their clusters, their SLAs, their escalations.
  • Debug across the full stack, hardware to fabric to scheduler, when a training run degrades.
  • Run customer-facing incident communication with technical depth and no spin.
  • Turn recurring customer pain into engineering fixes with the production teams.

What We're Looking For

  • Supported large-scale compute customers (HPC, cloud, or AI labs) at a technical level.
  • Debug distributed systems methodically across layers you don't own.
  • Written incident updates customers trusted more after reading.
  • Push internal teams to fix causes, not symptoms, and follow up until they do.

Bonus

  • GPU training workloads.
  • InfiniBand or RoCE.
  • Slurm or Kubernetes.
  • NCCL debugging.
