# 校招 北京-LPU Operator / Compiler / Performance Engineer

岗位职责 / Responsibilities Build LLM inference software for the LPU (Language Processing Unit). Experience in any ONE of the following areas is sufficient: operator development, compiler development, or performance optimization. Core Responsibilities Develop and optimize inference operators/kernels such as GEMM and attention; tune tiling, data layouts, and data movement; validate correctness and performance across tensor shapes and precisions. Implement and optimize lowering from tensor graphs/IR to LPU ISA: operator fusion, on-chip buffer allocation, instruction scheduling, and code generation. Run microbenchmarks and end-to-end profiling to identify compute, memory-access, and synchronization bottlenecks; validate first-token latency, per-token latency, and throughput gains across input lengths and batch sizes. Co-design with architecture and runtime teams, evaluate trade-offs among compiler scheduling, operator implementations, and hardware resource usage, and add key workloads to regression tests. 任职要求 / Requirements Requirements Recent/new PhD in CS, EE, Automation, or related fields. Exceptional final-year Master’s students with strong relevant research or engineering track reco
