The posting

团队介绍：Data AML是字节跳动的机器学习中台，为抖音/今日头条/西瓜视频等业务提供推荐/广告/CV/语音/NLP的训练和推理系统。为公司内业务部门提供强大的机器学习算力，并在这些业务的问题上研究一些具有通用性和创新性的算法。同时，也通过火山引擎将一些机器学习/推荐系统的核心能力提供给外部企业客户。

课题介绍：大规模推荐系统正在越来越多的应用到短视频、文本社区、图像等产品上，期望进一步通过算法与工程Co-design，探索推荐算法和大语言模型/多模态理解的深度融合主要研究方向包括：LLM4Rec、跨端跨场景的Foundation Model、千亿级参数规模的模型 和 多模态大模型。工程上研究方向包括多模态样本的高效表征、基于PyTorch架构的高性能推理引擎与训练框架构建，以及异构硬件在推荐场景下的性能极限优化；算法侧研究方向包括LLM4Rec技术路径的设计、千亿级底座模型的研发以及多模态协同训练（Co-training）等核心课题，旨在通过技术创新定义下一代工业级推荐范式。

课题挑战： 1、千亿模型的训练和推理优化； 2、多模态表征统一与高效融合难度大； 3、Foundation Model的设计和工程优化； 4、算法工程协同设计与异构硬件适配复杂。

课题价值： 1、技术价值：突破多模态表征融合、超大规模模型训练推理瓶颈，完善算法与工程协同设计体系，推动异构硬件适配与高性能框架国产化落地； 2、业务价值：提升推荐精准度与泛化能力，突破现有推荐系统模态局限，赋能短视频、文本社区等多产品，降低算力成本，助力业务规模化增长。

1、2027届及以后毕业，博士在读，计算机、软件工程等相关专业优先； 2、熟练掌握Linux环境下的C/C++/Go/Python/Java等1至2种以上语言； 3、掌握分布式系统原理，参与过大规模分布式系统的设计、开发和维护； 4、有优秀的逻辑分析能力，能够对业务逻辑进行合理的抽象和拆分，良好的团队合作精神； 5、有强烈的工作责任心，较好的学习能力、沟通能力和自驱力； 6、有良好的工作文档习惯，及时按要求撰写更新工作流程及技术文档。

加分项： 1、熟悉Kubernetes架构，有丰富的云原生系统开发经验； 2、熟悉至少一种主流的机器学习框架（TensorFlow/PyTorch/MXNet）； 3、熟悉Django、Flask等相关技术，有其后端开发经验； 4、有以下某一方向领域的经验：AI Infrastructure，HW/SW Co-Design，High Performance Computing，ML Hardware Architecture(GPU，Accelerators，Networking)，Machine Learning Frameworks，ML for System，Distributed Storage； 5、有大规模云计算平台或私有云产品架构开发经验。

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.
