Job Description

• E-commerce shopping Agent architecture design: Design a shopping Agent for To C (consumer) users, covering intent understanding, task planning, product recall, tool calling, result integration, and multi-turn conversation pipelines.
• User intent and requirement understanding: Address natural language queries, ambiguous requirements, scenario-driven shopping, budget constraints, and preference expression to improve the Agent's ability to interpret users' real shopping intent.
• User memory and preference modeling: Build long- and short-term memory systems for e-commerce scenarios based on user conversation and behavioral data, model user preferences, and enhance the Agent's personalization capabilities.
• Tool-calling capability improvement: Design and optimize the strategies and pipelines for the Agent invoking tools such as search, recommendation, product details, review summarization, price comparison, promotions, inventory, and logistics.
• Multi-turn guided shopping dialogue: Build multi-turn dialogue capabilities for complex shopping decisions, including need clarification, preference follow-up, product filtering, candidate comparison, and purchase recommendation generation.
• Agent evaluation and effectiveness optimization: Build offline and online evaluation systems covering task completion rate, product relevance, recommendation accuracy, factual consistency, hallucination rate, conversion metrics, user satisfaction, latency, and cost.
• Online deployment and continuous iteration: Collaborate with product, engineering, search/recommendation, merchandising, and operations teams to drive large-scale application of Agent capabilities in company-wide To C scenarios.

Requirements

• Master's degree in Computer Science, Artificial Intelligence, Mathematics, Software Engineering, or a related field.
• At least 3 years of full time experience in algorithms, machine learning, NLP, search & recommendation, or LLM applications, including at least 1 year of hands-on practice with large model applications or dialogue systems.
• Prior development experience with at least one of the following directions: Agent orchestration, Agentic Search, Memory, Agentic RL.
• Prior experience with LLM application development paradigms, including Harness Engineering, Function Calling, context management, and LLM Eval.
• Strong proficiency in Python; able to drive algorithm solutions from experimental validation to online deployment.
• Strong understanding of To C product requirements for experience, latency, cost, stability, and security, with the ability to continuously optimize Agent effectiveness in real online scenarios.
• Strong business understanding, data analysis, problem decomposition, and cross-team collaboration capabilities.
• Prior hands-on experience with e-commerce guided shopping, intelligent shopping assistants, search/recommendation Copilots, or To C AI products in production will be a storng plus
• Prior experience with evaluation, A/B experiments, cost optimization, latency optimization, and stability governance for large-scale online LLM applications.
• Prior experience with Agent frameworks or complex workflow orchestration, such as Google ADK, LangGraph, OpenAI Agents SDK, etc.
• Experience with Agentic SFT / RL training is a plus.
