The Marketplace Intelligence and Data team builds data and AI solutions to support Shopee's business growth and operational efficiency. Our work spans recommendation and marketing algorithms, intelligent data products, and emerging AI applications.

As part of the team, you will work on Shopee's AI-powered seller chatbot, leveraging large language models (LLMs), AI agents, and reusable skills to improve seller support, business diagnosis, and operational assistance.
