We are seeking a senior iOS Software Engineer with deep experience building applications powered by Large Language Models (LLMs). This is a hands-on development role focused on creating the next generation of intelligent on-device experiences for Apple users.
You will be responsible for building cutting-edge iOS applications that serve as the primary interface for on-device AI. A key part of your role will be to explore and define the software architecture for a scalable, high-performance system that seamlessly integrates powerful LLM agents into the Apple ecosystem, all while prioritizing user privacy and on-device performance.
This role is for an expert iOS developer passionate about building the foundational architecture for AI-driven applications.
What Youll Build:
• AI-Powered iOS Applications: Architect and build innovative, high-performance on-device apps that showcase the power of intelligent LLM agents. • Scalable On-Device Architecture: Design the client-side frameworks and architectural patterns for integrating LLM systems efficiently on iOS. • LLM Agent Integration: Implement the software that connects user-facing applications to on-device and hybrid AI reasoning and planning engines. • Interactive AI Prototypes: Rapidly build and iterate on application prototypes to explore new user interactions and architectural options.
Impact: This is a unique opportunity to define the future of intelligent applications at Apple. You will be at the center of building a new class of on-device experiences, setting the architectural foundation for how millions of users will interact with AI on a daily basis.
Lead the development of sophisticated iOS frameworks and applications that integrate directly with on-device LLM systems on Apple platforms. Architect robust, scalable, and power-efficient software patterns for AI-powered features on iOS. Collaborate with ML and AI researchers to translate cutting-edge models into tangible application features. Implement and optimize the on-device components for LLM inference, context management, and tool execution. Drive the technical roadmap for on-device AI application architecture.
