- # About us
**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.
## About the Role
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.
##
What You’ll Do
- 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.
## How We Work
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.
## Requirements
- 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.
## Bonus If You’ve…
- 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.
