Within this org, the Payment Data Intelligence team applies data science and machine learning to improve payment services at scale. The team leverages large-scale datasets and advanced algorithms to power business-critical use cases including financial risk control, payment compliance, user growth, and operational optimization — at the intersection of ML, data infrastructure, and real-world fintech challenges.

This internship focuses on building agent-first AI applications for payment scenarios. The role is designed for candidates who want to apply the latest AI paradigms, including LLM-based agents, workflow orchestration, prompt engineering, MCP-based tool integration, and AI application evaluation, to solve practical payment business problems.

• Design and develop agent orchestration workflows, including task decomposition, tool selection, memory/context design, human-in-the-loop checkpoints, and failure handling.
• Implement agent workflows visually on Agent Platform or programmatically using LangGraph-like scripts, depending on the use case and production requirements.
