Sr. Software Engineer, AI, Search&Knowledge Platforms, Santa Clara

Our team builds the foundational systems that power search across Apple - from Siri to Apple Music to the App Store and beyond. We develop agentic orchestration frameworks, configuration management infrastructure, services and APIs that enable product teams to deliver fast, reliable, and intelligent search experiences to hundreds of millions of users. We"re looking for a Senior Software Engineer to design and build the distributed systems that underpin search at Apple scale. You will work at the intersection of large-scale backend infrastructure and agentic orchestration— creating frameworks that coordinate complex, multi-step search workflows across services. Your work will directly impact how quickly and reliably Apple products can deliver search results to users worldwide.\\n\\nAs part of a platform team, you will have the opportunity to work with many other teams across the organization and across the company. You will also participate in many key technical decisions that will shape the future of search at Apple. Design and implement distributed frameworks for agentic orchestration — systems that coordinate autonomous, multi-step workflows across heterogeneous services\\nBuild and evolve configuration management infrastructure that allows teams across Apple to safely and rapidly tune search behavior at scale\\nOwn the reliability and performance of platform-level services handling high-throughput, low-latency search traffic\\nDefine technical direction for framework APIs and abstractions consumed by multiple product teams\\nCollaborate with teams across Apple (Siri, Music, App Store, and others) to understand their needs and translate them into scalable platform capabilities\\nIdentify and resolve systemic performance bottlenecks, reliability risks, and architectural gaps\\nMentor engineers on the team and contribute to a strong engineering culture 5 years of professional software engineering experience, focusing on backend development\\nProficiency in one or more programming languages such as Go, Rust, C++ or Java is required\\nDeepunderstanding of distributed systems — consensus, fault tolerance, consistency models, and graceful degradation\\nExperience designing and operating large-scale backend services (high QPS, low-latency requirements)\\nTrack record of leading cross-team technical initiatives from design through delivery\\nExcellent written and verbal communication skills\\nStrong focus on collaboration and collaborative problem solving Experience building orchestration or workflow execution frameworks (e.g., DAG-based execution engines, agent-based systems, or task schedulers)\\nFamiliarity with configurationmanagement at scale — feature flagging, dynamic config propagation, rollout safety\\nExperience with search or information retrieval systems\\nExposure to agentic AI patterns — tool use, planning, multi-agent coordination\\nContributions to platform or infrastructure teams where your users areother engineers
