Baseten is hiring a software engineer to build the networking layer beneath its distributed LLM inference stack: integrating RDMA, RoCE and InfiniBand rather than TCP/IP, tuning communication for disaggregated KV cache offload and wide expert parallelism, cutting trillion-parameter model cold starts below ten seconds, validating throughput on H100 and Blackwell clusters, and writing communication kernels with NCCL and NVSHMEM. The posting asks for deep high-performance networking experience, C++ or Python, and NVIDIA memory-hierarchy knowledge. Hybrid, across five listed cities.
