About the Job

Requirements

  • Experience and demonstrated expertise appropriate to a senior systems engineering role, as reflected in the stated compensation criteria.

Responsibilities

  • Drive core compute operator development and distributed scaling performance across foundation model pre-training and post-training workloads on Ascend NPUs.
  • Identify computational and communication bottlenecks and implement high-performance kernels using AscendC, Triton, and TileLang.
  • Design, implement, and tune core operators, including FlashAttention variants, FP8/MXFP8/W4A8 GEMM, Fused RMSNorm, and dynamic MoE routing/dispatch, using AscendC, with exploration of Triton (Triton-Ascend backend) and TileLang.
  • Architect, scale, and optimize distributed pre-training and RL post-training pipelines using MindSpeed (MindSpeed-LLM / MindSpeed-MM) alongside upstream frameworks (Megatron-LM / Megatron-Core, PyTorch FSDP, veRL, vLLM, and Ray).
  • Tune multi-dimensional hybrid parallelism (TP, PP, CP, EP, ZeRO/FSDP) and RL rollout/actor pipelining on Ascend NPU clusters to achieve optimal MFU and compute-communication overlap.
  • Implement low-precision training and inference schemes (FP8, MXFP8, and mixed-precision), ensuring numerical stability, batch-invariance, and strict precision parity between training and serving runtimes.
  • Conduct performance profiling on Ascend hardware using Ascend Profiler (msprof), msprobe, and PyTorch Profiler to eliminate pipeline bubbles, AICore/AIVector stalls, and HCCL communication overhead.
  • Contribute high-performance operators, bug fixes, and acceleration features to open-source Ascend communities and upstream AI acceleration projects.
