About the Team

We are the User Growth Algorithm Team for Global E-Commerce — the core engine driving the explosive growth of TikTok's global e-commerce business. Here, we go beyond solving conventional recommendation and user reach problems; we are committed to reshaping the shopping experience of global consumers through cutting-edge promotion algorithms. As the Promotion Algorithm Team, we command massive budgets and enormous traffic flows.
