About the role

Own and develop ATG's first iOS app end-to-end, from architecture to polish
Architect and ship the iOS app—from private beta to App Store release
Implement core features with fluid UI, high performance, and scalable client infrastructure
Create pixel-perfect UI, smooth animations, and thoughtful micro-interactions
Collaborate closely with founders, product, and design on prototyping and product direction
Build testing pipelines (unit tests, CI/CD) to maintain high reliability while moving fast
Deploy platform-level improvements (real-time syncing, on-device ML, efficient data flow)
Iterate quickly on new iOS experiences to make AI useful, intuitive, and delightful
Prioritize performance, reliability, and responsiveness to deliver best-in-class mobile experiences

3+ years of hands-on iOS experience (Swift, UIKit/SwiftUI, Combine, concurrency)
Shipped at least one app to the App Store and evolved it based on real-user feedback
Comfortable shipping fast while maintaining quality (modular design, unit tests, CI, profiling)
Resourceful: you choose the right tools, work lean, and thrive without heavy scaffolding
Strong product sense: you care about UX and sweat the details
Clear communicator—whether debugging, brainstorming, or shifting gears under pressure
Strong design sensibility and an eye for detail—experience working closely with UI/UX designers to create polished, high-quality mobile experiences
Expertise in leveraging the latest AI tools (Cursor, Claude Code, Codex, etc) to increase productivity & code output while maintaining high code quality, maintainability, and structure
