> 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.

## Job Description

## 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.
