Technical Lead - Applied AI Research, Agent Models

full-timePosted: Oct 29, 2025

Job Description

Join us at the forefront of redefining how people interact with their devices. On the Siri team we’re solving the challenge of building and shipping powerful LLMs that shape the way millions of Apple customers get things done every day. As a technical engineering leader, you will craft the future of on-device AI by developing powerful yet compact LLMs that bring personalized, private, and low-latency experiences to users. This is a high-impact role for a hands-on technical leader who thrives at the intersection of cutting-edge AI development and product delivery. In this role you’ll drive the design, development and delivery of large language models that power the core of Siri. You will lead research and engineer efforts in model post-training techniques that create powerful tool calling and compelling conversational models that run within the constraints of mobile hardware. You’ll collaborate closely with researchers, software engineers and product teams to move innovations from prototype to production. This includes identifying and applying post-training techniques, advancing model efficiency and contributing to the end-to-end model lifecycle process.
