- Experience with using communication libraries, such as MPI, NCCL, and UCX.
- Experience with developing, evaluating and debugging host networking protocols such as RDMA.
- Experience with triaging performance issues in complex scale-out distributed applications.
Preferred Qualifications
- Understanding of AI training workloads and demands they exert on networks.
- Understanding of RDMA congestion control mechanisms on IB and RoCE Networks.
