Staff
Build and operate the Kubernetes-based GPU superclusters that train Cohere's frontier models
Cohere's internal infrastructure team needs an engineer (the JD itself frames this 'As a Staff Software Engineer') to build and scale ML-optimized HPC infrastructure — Kubernetes-based GPU/TPU superclusters across multiple clouds — working directly with AI researchers on RDMA/NCCL-tuned distributed training. The interview covers deep Kubernetes-at-scale operations, low-level systems/networking knowledge, and self-service tooling design for researcher-facing workflows, plus 24x7 on-call ownership.
