• Significant side projects involving AI agents or production-grade LLM systems
• A strong academic or equivalent technical signal

Responsibilities

• Own the full agent architecture, including prompts, tool calling, multi-step reasoning, and streaming
• Productionize conversational state and memory systems that interpret user preferences
• Build ranking, retrieval, and recommendation experiences that surface useful, personalized results
• Improve multi-turn reliability through refinement loops, error recovery, and graceful degradation
• Design the rendering layer between agent output and the consumer product experience
• Manage model-provider strategy, caching, structured outputs, and fallback behavior
• Define and operate evaluation systems for ranking, retrieval, and agent behavior
• Debug production failure modes and continuously improve quality using evidence from real users
