We are seeking a highly skilled professional to join our team, focusing on advancing customer service scheduling optimization through innovative AI solutions. This role involves researching and implementing cutting-edge algorithms to enhance scheduling systems, leveraging business domain knowledge to elevate the impact of AI products. The successful candidate will develop and refine Large Language Models (LLMs) to extract actionable insights, improve business decision-making, and optimize prompt design for more accurate outputs. Additionally, the role includes creating scalable and robust LLM/RAG frameworks tailored to customer service scheduling, fostering innovation and maintaining a competitive market edge.

Responsibilities:

• Own the full LLM pipeline from data preparation to production real case usage.
• Design, iterate and optimize prompts (zero-/few-shot, chain-of-thought, tool-calling, etc.) to maximize model utility and safety across products and languages.
• Build and maintain Retrieval-Augmented Generation (RAG) QA/search systems that connect to multi-source knowledge bases.
• Familiar with vLLM/SGLang inference architectures and have proven experience deploying and operating LLM services on multi-GPU or cluster environments.
• Design, implement and operate multi-agent LLM architectures (e.g. LangGraph, CrewAI, AutoGen) including task decomposition, agent orchestration, memory sharing and tool-calling workflows.
• Develop evaluation pipelines (automatic metrics & human feedback) to measure prompt and model quality, bias, and hallucination rates.
• Collaborate with product and CS teams to integrate AI models into conversational Chatbot in different scenarios.
• Track cutting-edge research, author tech blogs, and keep improve current architecture.

Qualifications:

• Master's degree or higher in Computer Science, Data Science or related field..
• 2+ years of deep-learning/NLP experience, including 1+ year practical LLM work (SFT, DPO, RAG, quantization, inference optimization, etc.).
• Demonstrated prompt engineering & tuning expertise (few-shot design, structured prompting, prefix-/p-tuning, reward re-ranking, safety filtering).
• Practical experience building and deploying multi-agent LLM workflows, with understanding of agent-orchestrator patterns, shared memory, long-horizon planning and guard-rail design.
• Clean coding practices, good English communication skills, and a passion for rapid learning.
• Excellent self-driven and ownership with good deliverables.
• Eager to learn, be curious about AI new technologies
• Good communication and collaboration skills
