This role sits at the intersection of research, engineering, and solutions, you will play a critical cross role in measuring, understanding, and improving the capabilities of our models for our enterprise customers. What you will do - Design and implement comprehensive evaluation frameworks to measure LLM capabilities across diverse customer use cases, including text generation, reasoning, code, and domain-specific applications - Build scalable evaluation infrastructure and pipelines that enable rapid, reproducible assessment of model performance - Develop novel evaluation methodologies to assess emerging capabilities or verticalized use cases (cybersecurity, finance, healthcare, etc.) and enable the Solutions (Deployment Strategist and Applied AI) on these topics. - Create custom evaluation suites tailored to enterprise customers' specific needs, working closely with them to understand their requirements and success criteria - Collaborate with research teams to translate evaluation insights into model improvements and training decisions - Partner with pr
