About the Job

Requirements

  • Complete or have recently completed a Bachelor's or Master's degree in Software Development, Computer Science, Computer Engineering, or a related technical discipline.
  • Have strong research or practical experience in natural language processing, computer vision, generative models (such as Diffusion, GANs, or ControlNet), multimodal learning, large models, or Agents.
  • Be proficient in PyTorch or TensorFlow and have hands-on experience in model training, tuning, and deployment.

Responsibilities

  • Build global product catalog and content understanding systems, modeling products, videos, images, merchants, and brands with structured and semantic representations.
  • Develop algorithms for identical product matching, product, merchant, and brand deduplication, and cross-lingual product aggregation, addressing multimodal matching, real-time aggregation, multi-granularity clustering, and semantic alignment.
  • Build pricing algorithms for price comparison, product pricing, price monitoring, and anomaly detection, supporting subsidy programs, price competitiveness analysis, and supply optimization.
  • Construct multimodal semantic links across video-product, product-product, and video-video relationships to support trend understanding, product mining, AIGC generation, and content-commerce supply optimization.
  • Explore next-generation generative search and recommendation through full-format representation learning and SID modeling across videos, livestreams, products, and queries.
  • Design and develop generative algorithms for engaging, high-conversion e-commerce visual creatives, addressing identity-preserving and aesthetic style consistency for production-grade intelligent background synthesis, virtual try-on, and localized lifestyle scene generation.
  • Explore business-facing Agents such as price comparison Agents, product analysis Agents, content AIGC Agents, and merchant operation Agents, leveraging RAG, tool calling, planning, reasoning, and automated evaluation.
  • Own the end-to-end algorithm workflow, including data construction, model training, evaluation, deployment, bad-case analysis, and continuous iteration.

Desired Qualifications

  • Experience with LLM/VLM, Embedding/SID, RAG, Tool Calling, or Agent Planning.
  • Experience with distributed training, mixed precision, inference acceleration, TensorRT, or LLM serving optimization.
  • Experience in multimodal retrieval, product understanding, content understanding, search/recommendation, pricing algorithms, intelligent Agents, or AIGC projects.
  • Familiarity with Video LLMs, Multimodal Reasoning, vision-language alignment, long-video understanding, or generative search/recommendation.
  • Publications, open-source contributions, or strong algorithm competition records.
