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. Why Join ATG We're building a small, elite team. If you're excited by AI, markets, and building from first principles, we’d love to meet you. • Work on AI with a massive market opportunity • Early team of repeat founders backed by top investors • High agency, talent dense, zero bureaucracy
