iOS Engineer

About this role

Join a stealth AI startup building consumer-grade AI agents, and lead the iOS experience from ground up. You'll architect and ship an elegant native iOS app that integrates on-device LLM inference with Apple's frameworks, making AI feel like a first-party Apple feature.

What you'll do

• Own the iOS app architecture, performance optimization, and polish end-to-end
• Develop on-device agent runtime leveraging Apple Neural Engine and frameworks like Core ML, MLX, and App Intents
• Handle App Store compliance, entitlements, background execution, and power management
• Prototype novel iOS interaction patterns for agentic systems
• Collaborate with research on model optimization for Apple silicon constraints
• Establish iOS engineering standards and mentor other engineers on native best practices

What they're looking for

• Expert iOS development with Swift and deep UIKit/SwiftUI knowledge
• Performance profiling and optimization on Apple devices
• Integration with Apple frameworks (Core ML, MLX, App Intents, Live Activities, Shortcuts)
• App Store submission and review process expertise
• Understanding of LLM inference and on-device model execution
• Native app design aligned with Apple Human Interface Guidelines
• Background execution and power optimization
• Git, debugging, and modern iOS development tooling

Benefits

• Competitive cash compensation and meaningful equity
• Top-tier relocation and immigration support
• Work with elite team from Stanford, OpenAI, and DeepMind
• Shape the future of consumer AI on iOS
• San Francisco in-person office
• Access to cutting-edge AGI research and prototyping
