ATG (Autonomous Technologies Group) is an AI lab deploying frontier reasoning systems within financial markets.
Founders: Early GPU cloud (9 figure exit).
Investors: Garry Tan / YC + Founder of one of the most successful quant funds, BoxGroup (Plaid, Ramp, Stripe), top-tier angels.
We’re looking for a software engineer to help develop, launch, and maintain the first version of the ATG iOS app. This is a zero-to-one role: you’ll own the mobile experience end-to-end, from architecture to polish. Your work will directly shape how users interact with ATG, shaping the future of mobile AI experiences. As a key member of our team, you'll push the boundaries of iOS development, combining technical excellence with design finesse. From pixel-perfect UI to smooth animations and thoughtful micro-interactions, you’ll create seamless, motion-driven experiences that delight users. If you excel in building high-quality, intuitive, and visually stunning apps, this role is for you.
Architect and ship our first iOS app—from private beta to App Store release.
Implement core features with fluid UI, high performance, and scalable client infrastructure.
Collaborate closely with the founders, product, and design on prototyping, and product direction.
Build testing pipelines (unit tests, CI/CD) to keep reliability high while moving fast.
Deploy platform-level improvements (real-time syncing, on-device ML, efficient data flow).
Iterate quickly on new iOS experiences that make AI useful, intuitive, and delightful in every user’s pocket.
Prioritize performance, reliability, and responsiveness to deliver best-in-class mobile experiences.
We’re early, fast, and ambitious. Every engineer has a direct line to product decisions and user impact. We optimize for:
User delight — clean, intuitive, responsive experiences.
Speed with quality — ship quickly without cutting corners on reliability.
High impact — focus on features that move the needle for users.
Collaboration — work directly with founders in a flat, high-trust environment.
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.
Experience integrating ML models on-device or in-app.
Built dual-platform experiences (iOS + Android or iOS + Web).
Led iOS architecture: modular features, performance tuning, advanced debugging.
