The Role As a Lead AI Engineer, you will build and operate production AI systems that improve Hyatt’s search, personalization, guest experiences, colleague productivity, and operational workflows. This is a hands-on individual-contributor role focused on technical leadership in machine-learning engineering, system design, observability, agentic application delivery, retrieval systems, and fast, reliable LLM inference. Search, Personalization, and Retrieval Design and build scalable AI systems for natural-language search, semantic retrieval, ranking, recommendations, and personalized guest experiences. Develop low-latency retrieval and ranking pipelines that combine keyword search, embeddings, vector retrieval, reranking, business rules, and real-time contextual signals. Partner with data scientists to productionize relevance models, recommender systems, and LLM-powered search experiences. Define online and offline experimentation approaches, including relevance metrics, latency targets, A/B tests, and business-impact measurement. Fast LLM Inference and Production Engineering Lead the design of high-throughput, low-latency LLM inference services for real-time guest and colleague experiences. Optimize serving performance through model selection, quantization, batching, caching, streaming, routing, autoscaling, and efficient GPU utilization. Evaluate hosted, open-weight, fine-tuned, and smaller task-specific models based on quality, cost, reliability, privacy, and latency requirements. Build production APIs and services for model inference, embeddings, reranking, retrieval, and agent execution. Partner with ML engineering and platform teams to deploy systems using AWS-native services and modern containerized infrastructure. Agentic AI and Multi-Agent Systems Architect and implement agentic AI applications that use LLMs, tools, retrieval, workflows, memory, and structured decision-making. Build agent-to-agent systems in which specialized agents can delegate work, share relevant context, coordinate on tasks, and produce auditable outcomes. Design reliable orchestration patterns for multi-step workflows, including planning, tool execution, state management, retries, handoffs, approvals, and fallback behavior. Establish secure agent interfaces for enterprise tools and data, with strong identity, authorization, tenant or property isolation, traceability, and policy enforcement.
