About The Team

Shopee will be prioritizing applicants who have a current right to work in Singapore, and do not require Shopee sponsorship of a visa.

Kindly note that you can only be considered in one recruitment process at a time within Sea Group and will be considered for jobs in the order that you have applied.

The Marketplace Intelligence and Data team's mission is to build sustainable and efficient data and intelligence products to facilitate Shopee's business development. The team is responsible for Shopee e-commerce data warehouse construction, merchant and operation data product construction, all-link traffic data, product algorithms, including product release, control, information optimization, SPU library and its comparison business, marketing algorithms, including Merchandising, Product Selection, Recommendation Algorithm, Evaluation Algorithms, User Profiling, and in addition, basic AI capabilities, such as Machine Translation, Speech Algorithm, Image Algorithm, and Real-person Authentication.

We are the Shopee Intelligent Customer Service Chatbot team based in Singapore, dedicated to exploring cutting-edge AI technologies, including but not limited to large language models (LLMs), natural language processing, deep learning, and knowledge graphs. Our mission is to tackle core challenges in multilingualism, context, and human-machine collaboration in Q&A and dialogue systems. We aim to revolutionize the service experience for consumers in Southeast Asia and globally.

By integrating state-of-the-art algorithmic technology, robust engineering foundations, thoughtful product design, and intelligent operations, our team has developed a rich, efficient, and high-performance Q&A technology system. This system significantly supports markets in Southeast Asia, including Singapore and Indonesia, as well as the South American market, including Brazil, effectively addressing the vast differences in customer service demands and controlling costs while improving customer satisfaction.

The rise of large language language models has opened up vast possibilities in the field of customer service. Natural dialogue and task-driven scenarios are crucial stages for showcasing the capabilities of LLMs. Here, you have the opportunity to build algorithmic systems based on large language models, redefining chatbots and agent assistance products, and bringing a novel user experience to a broad consumer base.
