Senior Software Engineer, On-Device Health Agentic Systems

e, and autonomous capabilities, all while prioritizing user privacy and on-device performance.","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

Cross-Functional Collaboration: Partner with product managers, UX designers, and ML researchers to translate product requirements into technical specifications and deliver high-quality, impactful features
