The Engineering and Technology team is at the core of the Shopee platform development. The team is made up of a group of passionate engineers from all over the world, striving to build the best systems with the most suitable technologies. Our engineers do not merely solve problems at hand; We build foundations for a long-lasting future. We don't limit ourselves on what we can or can't do; we take matters into our own hands even if it means drilling down to the bottom layer of the computing platform. Shopee's hyper-growing business scale has transformed most "innocent" problems into huge technical challenges, and there is no better place to experience it first-hand if you love technologies as much as we do.
Job Description:
- Design and develop core agent algorithms, including multi-turn dialogue planning, tool orchestration (retrieval, ranking, LLM synthesis), and adaptive task planning.
- Build and maintain agent memory architectures using knowledge graphs to support long-term consistency, personalization, and context retention across sessions.
- Develop emotion-aware dialogue modeling techniques to improve agent naturalness, consistency, and user engagement.
- Design and implement LLM alignment and safety strategies (e.g., SFT, DPO) to mitigate risks such as implicit persuasion or psychological manipulation in personalized generation.
- Build multimodal agent capabilities that integrate vision-language reasoning with dialogue planning for tasks such as tutoring or adaptive guidance.
- Benchmark and deploy LLMs/VLMs across GPU clusters and cloud environments (e.g., AWS); build reproducible evaluation pipelines to support model and architecture selection.
- Track frontier research in agent algorithms, contribute to publications, and represent findings at top-tier AI/NLP venues.
Requirements:
- Master's degree or above in Computer Science, Natural Language Processing, Artificial Intelligence, or a related field.
- Minimum 3 years of hands-on research and engineering full-time working experience building conversational agents with knowledge-graph-based memory systems, persona-aware and emotion-aware dialogue modeling, and LLM alignment techniques (SFT and DPO) for safety and behavior control, combined with experience orchestrating agent pipelines involving retrieval, ranking, and tool use.
- First-author publication(s) at top-tier venues (ACL/AAAI/EMNLP/ICLR) on persona-driven dialogue generation and persona attribute extraction, particularly methods that improve dialogue consistency and personalization quality.
- Demonstrated experience building vision-language tutoring/dialogue agents that integrate multimodal reasoning with adaptive dialogue planning, applying reinforcement learning (e.g., Deep Q-Networks) to sequential decision-making problems, and developing end-to-end 3D reconstruction pipelines (segmentation, planar extraction, geometric reconstruction) from point cloud data.
- Good programming skills in Python and Bash; proficient in PyTorch and Hugging Face; familiar with LoRA/PEFT, prompt engineering, and model evaluation pipelines.
- Experience benchmarking and deploying LLMs/VLMs across GPU clusters and cloud platforms (e.g., AWS EC2); familiar with data systems such as PostgreSQL, Neo4j, and AWS S3.
- Good problem analysis and research skills; sustained curiosity in frontier AI/agent research; able to work independently and collaboratively across research and engineering teams.
