Customer Reliability Engineer

Our customers run large AI training and inference workloads on GPU clusters we source from providers worldwide. When a node goes dark or a job dies eight hours into a run, the Customer Reliability Engineer is who they hear from, and who gets it sorted.

The job has three parts. You triage incoming issues and debug them at the Linux and Kubernetes layer. You work provider-side to figure out whose fault something actually is and push external providers to fix it. And you build the monitoring and scripts that catch problems before a customer has to tell us.

You need to be comfortable in a Linux shell and know how Kubernetes works. You don't need GPU or HPC experience. Most people pick that up here.

• Own issues start to finish: reproduce, diagnose, fix or escalate, close the loop

• Debug at the Linux layer: processes, networking, storage, kernel logs, resource contention, systemd, journald

• Dig into Kubernetes problems like pods stuck pending or crash-looping, node conditions, scheduling failures, resource limits

• Work GPU failures: driver and device-plugin issues, XID errors, thermal throttling, nodes that need cordoning or draining, jobs failing across multiple nodes

• Escalate when you're past your depth, with the evidence already gathered

• Take part in a 24/7 on-call rotation

• First response on alerts and customer-reported outages: assess impact, set severity, pull in the right people

• Keep customers updated during incidents. Clear status, honest unknowns, no silence

• Write up what happened, then turn it into a runbook, an alert, or a fix so it costs less next time
  

• Work out whether a fault is provider-side, ours, or the customer's before it gets handed anywhere

• Open tickets with compute providers and chase them down rather than waiting

• Track recurring provider failures and flag the patterns to the people making sourcing decisions

• Write Python or Bash to automate the checks you'd otherwise run by hand

• Build and improve monitoring: cluster and node health checks, GPU telemetry, dashboards, alerts that fire on real problems

• Keep runbooks and customer docs current as you go

• Real Linux troubleshooting ability from the command line. You can work a problem through logs, processes, networking, and disk without a script to follow

• Working knowledge of Kubernetes: pods, nodes, deployments, services, scheduling, and how to investigate when one of those breaks

• Can write a script in Python or Bash to automate something repetitive

• Strong writing. You can explain a technical problem to a frustrated customer clearly and without condescension

• Good judgment under pressure. You know what to check first, when to escalate, and how to keep people informed while you're still working it out

• Willing to join a 24/7 on-call rotation

• Hands-on time with NVIDIA GPUs in production: drivers, CUDA, DCGM, the Kubernetes device plugin

• Experience with high-performance networking (InfiniBand, RoCE) or NCCL

• Experience with HPC or batch schedulers like Slurm

• A previous customer-facing technical role: support engineering, TAM, solutions, professional services

• Knowledge of Prometheus, Grafana, Datadog, or similar

• IAC: Terraform, Ansible, or Helm

• Genuine interest in AI infrastructure and how big training jobs behave

• High-growth environment: Get in early at a company at the center of the AI infrastructure boom

• Competitive compensation: + meaningful equity

• Comprehensive benefits: for you and your dependents, including healthcare, dental, and vision coverage, 401(k), and unlimited PTO
