Description
Summary
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.
Description
What You'll 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.
Key Responsibilities
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.
Minimum Qualifications
5+ years of professional software development with expert-level experience building high-performance, consumer-facing mobile applications and frameworks.
Strong proficiency in a modern systems programming language such as C++, ObjectiveC/Swift, or Rust. A demonstrated ability to quickly master new languages and platforms is highly valued.
Deep understanding of mobile system fundamentals: concurrency, memory management, and power optimization.
Practical knowledge of how LLM-powered systems work, including prompt engineering, agent frameworks, or RAG architectures.
Preferred Qualifications
Experience with on-device ML frameworks like Core ML, Foundation Model, etc.
Experience in SwiftUI and modern iOS architectural patterns.
Knowledge of model quantization, caching, and other on-device optimization techniques.
Experience with multi-platform development (e.g., building for both iOS and macOS).
