As a Model Behavior Architect on the Function Calling team, you will be at the forefront of defining and measuring how Large Language Models (LLMs) utilize tools, invoke functions, and orchestrate complex agentic workflows. We are seeking individuals with a strong background in engineering, machine learning, and LLMs, who possess expertise in model evaluation, policy writing, and creating evaluation pipelines specifically for tool use and function calling. Your primary responsibility will be to collaborate closely with our Science team to establish benchmarks for function calling performance, covering aspects such as accurate parameter selection, schema adherence, multi-step tool orchestration, error recovery, and agentic reasoning. This role is ideal for those passionate about tackling cutting-edge, open-ended research challenges and translating insights into best-in-class models.
