• Build production AI systems on large language models, including tool use, retrieval, structured outputs and orchestration.
• Develop evaluation practices using real-world datasets, graders and experiments to measure improvements.
• Design the data layer, services and interfaces that these systems rely on, connecting with customers' existing business software.
• Standardize how new customer implementations are delivered so that onboarding gets smoother over time.
