Cerebras is hiring a software engineer for its Host and Network IO team, which builds the IO path linking distributed server nodes, the cluster, a custom RoCE stack and the company's wafer-scale engine. Work covers x86 and ARM software, an internal IO API, hardware control subsystems, performance debugging of large AI clusters, packet-trace analysis and telemetry, plus kernel-bypass and zero-copy optimisation. The posting asks for a master's or PhD plus a year of experience, or three years in industry, with socket programming, RDMA Verbs, and network-protocol and switch familiarity.
