Senior Engineering Manager, Agentic AI & Intelligent Reasoning

Apple is where individual imaginations gather together, contributing to the values that lead to great work. Every new idea has the potential to become an extraordinary product, service, or customer experience. The AI, Search & Knowledge Platforms team builds the foundational intelligence powering Siri, Apple Intelligence, Spotlight, Safari, and intelligent experiences across the Apple ecosystem. We are seeking an exceptional Senior Engineering Manager to lead the engineering organization responsible for Agentic AI and Intelligent Reasoning. This team is building the next generation of AI systems capable of understanding complex user intent, orchestrating multi-step reasoning, retrieving and synthesizing knowledge, and delivering deeply personalized, accurate, and trustworthy experiences. You will lead a world-class organization of machine learning engineers, software engineers, and applied scientists developing agentic AI frameworks, reasoning systems, planning engines, memory architectures, and orchestration platforms that enable Apples AI experiences to solve increasingly sophisticated user problems while maintaining Apples industry-leading standards for privacy, reliability, and user trust.In this role, you will define the vision, technical strategy, and execution roadmap for Apples Agentic AI answer & knowledge platform, enabling Siri, Apple Intelligence, Spotlight, Safari, and future intelligent experiences to answer increasingly complex user questions through reasoning, planning, retrieval, and intelligent orchestration. You will lead end-to-end engineering and applied research to build AI agents capable of understanding complex user goals, decomposing multi-intent requests, performing multi-hop reasoning across heterogeneous knowledge sources, executing long reasoning chains, conducting deep research, and synthesizing grounded answers that integrate world knowledge with users personal context while preserving privacy. Your organization will develop state-of-the-art agentic architectures that dynamically orchestrate large language models, retrieval systems, reasoning engines, planning modules, memory systems, structured knowledge, and external tools to deliver intelligent, context-aware experiences. These systems will support sophisticated workflows requiring iterative reasoning, evidence gathering, verification, contextual understanding, and personalized response generation. You will drive innovations in planning, task decomposition, retrieval orchestration, long-context reasoning, memory management, tool use, agent collaboration, and adaptive execution to significantly improve answer relevance, factuality, freshness, completeness, and user satisfaction across Apples AI ecosystem. You will partner closely with foundation model, retrieval, knowledge, ranking, search, personalization, and product teams to develop scalable AI systems that intelligently combine user context, device context, trusted web information, structured knowledge, and Apples ecosystem data while maintaining strict privacy guarantees through on-device intelligence and Private Cloud Compute. You will also lead the development of robust evaluation frameworks, simulation environments, safety guardrails, reasoning benchmarks, observability systems, and continuous learning pipelines to measure and improve agent quality across complex reasoning, grounding, planning accuracy, factual consistency, personalization, and user experience. As a senior engineering leader, you will build and mentor high-performing engineering managers and technical leaders, establish long-term organizational strategy, foster technical excellence, and successfully execute ambitious multi-year roadmaps that shape the future of AI across billions of Apple devices worldwide.MS or Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, Natural Language Processing, or a related technical field. 8+ years of experience leading engineering organizations delivering large-scale AI, machine learning, or distributed systems in production.
