The posting

团队介绍：国际电商是以TikTok为载体的电商业务（也称为TikTok Shop），致力于成为用户发现并获取优价好物的首选平台，在直播电商、视频内容电商、货架电商等多场景下，国际电商希望能为用户提供更个性化、更主动、更高效的消费体验，为商家提供稳定可靠的平台服务，致力于新奇好物畅销全球，美好生活触手可得的使命。 Data-电商团队是国际电商的核心算法技术力量，专注于电商领域的算法创新，帮助用户高效发现感兴趣的商品，保障用户的购物安全，提升交易各环节的智能化水平。在这里，你将与一流的产品和技术团队合作、钻研，一起应对技术和业务上的挑战，推动技术在电商场景的深度落地。

课题介绍： 国际电商生态中沉淀了用户行为、商品图文、多媒体内容、商品销量与物流时序等海量异构数据，但传统模型在长周期预测、跨模态理解及复杂决策推理上仍存在明显瓶颈。 本课题拟以大模型为基础，联合构建面向国际电商场景的基础大模型，将用户、商品、内容、物流与库存等关键信息统一建模，并在其之上设计可插拔的Agent框架，系统整合任务规划、工具调用、多轮交互与环境感知等能力，从而在需求预测、流量分发与个性化推荐等链路中实现端到端的智能决策。

课题挑战： 1、异构融合与对齐：统一建模用户行为序列、商品销量时序信号与多模态商品内容，完成高维时序与图文表征的深度语义对齐； 2、推荐大模型与世界模型协同：把推荐问题定义还原为用户推荐列表的生成问题，基于大模型的技术完成端到端推荐建模； 3、推荐物品的Tokenizor：如何把亿级别的物品进行多模态和特征语义编码，支撑后续训练和生成任务，处理几十TB级别的用户行为Tokens的预训练，通过模型结构和训练方式拉高Scaling Law曲线，把各类推荐任务重构为后训练任务，以RLVR的思路进行推荐任务建模，最大化GMV和体验价值，训练推理优化，基于SGLang 等大模型推理套件定制构建高性能的推荐服务； 4、电商多模态大模型：构建面向电商领域的多语言多模态大模型，在核心电商场景达到SOTA性能，并以此为基础打造电商智能体基座，广泛支撑各类电商场景下的Agent应用落地； 5、Agent评测与安全合规：构建贴合实际业务的Agent评测指标与基准，保障在强约束、强对抗环境下的稳定性、安全性与合规性。

课题价值： 1、技术价值：打造通用多模态基座，以模型、数据、算力迭代实现幂律增长，夯实规模化技术底座； 2、业务价值：搭建国际电商大模型底座，以生成式推荐、时序大模型、Agent等驱动GMV与留存，打造高杠杆营收引擎。

1、2027届毕业，获得博士学位，计算机等相关专业优先； 2、扎实的机器学习技术基础，了解前沿的AI技术，发表过高水平学术会议论文或有竞赛经验； 3、熟悉大数据相关框架和应用Hadoop、MapReduce/Spark等； 4、熟悉TensorFlow/PyTorch模型的训练和部署，了解混合精度训练、分布式训练等训练加速方法； 5、了解模型压缩&推理加速的研究和技术进展，包括但不限于模型量化、剪枝、蒸馏、TensorRT推理优化等； 6、熟悉以下任一方向的技术： 1）CV&多模态：在多媒体和计算机视觉某个领域有较深入的研究，包括但不限于：图像搜索、图像/视频分类和识别、图像分割、目标检测、OCR、图神经网络、多模态、无监督和自监督学习等；有CV/多模态大模型相关项目经验，研发&优化电商视频&商品多模态大模型，结合LLM和视频/商品表征，支持视频多模态分类，视频QA，跨模态检索，商品分类等任务，显著超越线上模型；有较强的实践能力，在Kaggle，COCO，ImageNet，ActivityNet，ICPC等比赛获奖；熟悉前沿工作，在顶级学术会议（如CVPR、ICCV、ECCV等）发表论文； 2）自然语言处理（NLP）：NLP方向上有较深入的研究，包括但不限于：预训练技术，自然语言理解，多语言&跨语言学习，自然语言生成，迁移学习，半监督学习等；有LLM大模型相关项目经验；研发NLP大模型，以统一电商场景的NLP任务，落地电商业务场景；有较强的实践能力，在Kaggle，GLUE，Super GLUE，CLUE等比赛获奖；熟悉前沿工作，在顶级学术会议（如ACL、EMNLP等）发表论文。

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.
