Apple is seeking a Software Engineer to pioneer the next generation of intelligent, on-device experiences by bridging the gap between powerful LLMs and the resource-constrained environment of mobile devices.
Requirements
- Experience working with on-device LLMs or other on-device ML models (e.g., using Core ML, TensorFlow Lite, or PyTorch Mobile)
- Hands-on experience with agentic frameworks or tool-use architectures (e.g., LangChain, custom agents)
- Strong skills in Swift (desired) and at least one other object-oriented programming language
- Experience with on-device databases (e.g., Core Data, Realm, SQLite)
- Experience with multi-platform development or building systems that operate across different operating systems
- Knowledge of model quantization, pruning, and other on-device optimization techniques
- Experience with distributed systems and client-server communication
Responsibilities
- Architect and Develop Agentic Systems: Design and build the core architecture for on-device agents and the tools they will use. This includes creating the agentic reasoning and planning layer, the on-device tool registry, and the data-flow pipelines
- On-Device LLM Integration: Integrate on-device LLMs to run efficiently on iOS devices, managing memory, power consumption, and compute resources
- Hybrid On-Device/PCC Architecture: Engineer a seamless system that can execute agentic workflows and tool calls both on the user's device and on a personal computer, ensuring a consistent and reliable user experience across platforms
- On-Device Data and Input Integration: Design and build robust integrations with on-device databases (e.g., Core Data, SQLite), and other device inputs like user location, motion data, and sensor data, to provide rich context for the agents
- Tool Building and Management: Create a flexible and scalable 'tooling' framework that allows agents to interact with various applications and data sources on the device (e.g., health, location, calendar, etc.)
- Performance and Privacy Optimization: Continuously monitor and optimize the performance of the on-device agents, focusing on latency, battery life, and resource usage. Ensure all data handling adheres to the highest standards of user privacy and security
- Technical Leadership: Serve as a technical leader within the team, providing guidance and mentorship to other engineers, participating in code reviews, and helping to set the technical roadmap for the agentic systems
Other
- Bachelor's degree in Computer Science or a related technical field, or equivalent practical experience
- 5+ years of professional software engineering experience, with a significant focus on mobile development (iOS)
- Proven experience building and shipping complex, high-performance applications that run on-device
- Excellent communication and collaboration skills, with the ability to articulate complex technical concepts to a variety of audiences
- The ability to thrive in a fast-paced, ambiguous environment where you are building a new and emerging technology
