The posting

1、核心技术研发:负责大语言模型(LLM)在推理阶段的架构级优化与加速,解决长文本(Long Context)推理及高并发场景下的性能瓶颈。 2、前沿技术落地:探索并实现大模型推理领域的最新前沿加速技术,包括但不限于 KV Cache 压缩/量化、Context 压缩、Special Token 深度定制、Layer Skipping(层跳过)、推测解码(Speculative Decoding)等。 3、推理框架协同:深入底层计算架构,配合或优化主流大模型推理框架(如 vLLM, TensorRT-LLM, DeepSpeed-FastGen, LMDeploy 等),提升系统吞吐量(Throughput)并降低首字延迟(TTFT)。 4、软硬件协同设计:针对不同硬件平台(如 NVIDIA GPU、算力芯片等)进行极致的算力算子调优,优化内存带宽与显存占用。

1、教育背景:计算机、电子信息、自动化或数学等相关专业硕士及以上学历。 2、专业经验:2年以上 大模型(LLM/VLM)相关研发经验,其中至少 1 年深入聚焦于大模型推理加速或底层吞吐调优。 3、深度理解LLM架构:熟练掌握 Transformer 架构原理,对 Attention 机制、注意力矩阵计算以及内存访问瓶颈有深刻理解。 4、加速技术常识:深入研究过并实际落地过以下至少两项技术: (1)显存与上下文优化:KV Cache Eviction/Quantization、PageAttention、长文本 Context 压缩/表征提取。 (2)架构与算子加速:Layer Skipping/Early Exiting 动态路由机制、Special Token 优化策略、FlashAttention/FlashDecoding 算子调优。 5、工程能力:精通 Python 和 C++/CUDA 编程,熟悉 PyTorch 框架,具备优秀的 Code Review 习惯。 6、框架经验:熟练使用或阅读过 vLLM、TensorRT-LLM 等至少一种开源推理框架的核心源码,有二次开发经验者优先。 加分项 在开源社区(如 vLLM, Hugging Face)有高质量 PR 贡献或维护知名加速开源项目者优先。 在 OSDI, SOSP, ASPLOS, ISCA, MLSys, NeurIPS, ICML 等系统或机器学习顶级会议发表过论文者优先。 拥有高性能计算(HPC)、并行计算(数据并行、张量并行、流水线并行)实际落地经验者优先。

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
