Collaborate with physics, clinical, and platform teams to translate prototypes into clinical-grade products.

Key Responsibilities

Be responsible for the fine-tuning of large language models, including supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), and domain-specific model adaptation, to improve model performance and adaptability in vertical scenarios.
Conduct in-depth research and optimization on Prompt Engineering, design high-efficiency and high-robustness prompt templates, and explore advanced prompt strategies to enhance model output quality and task completion efficiency.
Optimize the Function Calling capability of large models, improve the accuracy, stability and generalization of model tool invocation, and realize the seamless connection between models and external tools and services.
Conduct research and implementation on advanced model reasoning technologies, including Chain of Thought (CoT), reflection mechanism, multi-step reasoning, and long context management, to solve complex reasoning tasks and extend the effective context window of models.
Build a comprehensive LLM evaluation system, conduct all-round testing and evaluation on models, focusing on model hallucination problems, output stability, tool call accuracy, reasoning ability and other core indicators, and put forward targeted optimization plans.
Track the cutting-edge research progress and technical trends in the field of large language models, introduce advanced algorithms and technologies into business scenarios, and promote the continuous iteration and upgrading of model technology.
Be responsible for the research and development of the core Agent runtime system, including the design and implementation of execution engine, state machine, memory module and tool call framework, to ensure the efficient, stable and scalable operation of the Agent system.
Develop and optimize multi-Agent collaboration mechanisms, realize core functions such as dialogue routing, conflict resolution, task decomposition and aggregation, and build a collaborative system for efficient interaction and task division among multiple Agents.
Optimize the scheduling logic and execution efficiency of the Agent engine, solve the problems of task delay, memory overflow and tool call failure in the Agent operation process, and improve the overall performance of the system.
Design the Agent system architecture with high availability and high scalability, support the access of various types of large models and external tools, and meet the needs of complex business scenarios.
Be responsible for the connection and secondary development of mainstream open-source frameworks in the field of Agent, including LangChain, AutoGPT, OpenCWA, etc., and independently develop customized Agent frameworks and components according to business needs.
Collaborate with product, engineering and other teams to translate algorithm research results into implementable technical solutions, and support the landing and application of large model products.
Participate in agile processes: planning, estimation, retros, and on-call (as needed)
