Product Engineer - Frontend

You'll own the mobile app end-to-end from architecture to App Store release. Corpus is a conversational AI product, so the frontend isn't just screens; it's the entire experience layer where users build trust with their money. You'll work directly with the founders to ship the product users interact with every day.

Responsibilities:

• Architect and ship the Corpus mobile app from alpha to production release.
• Build fluid conversational UI, interactive charts, and generative UI blocks that render from AI tool outputs.
• Implement smooth animations, transitions, and micro-interactions that make the app feel premium.
• Own performance profiling, bundle optimisation, fast cold starts, and jank-free scrolling across devices.
• Integrate authentication (Clerk), push notifications, and real-time data syncing.
• Build and maintain a reusable component library and design system alongside the designer.
• Set up CI/CD, testing pipelines, and release workflows.

Requirements:

• 3+ years building production mobile apps with Flutter (Dart).
• Strong command of state management (Riverpod/Bloc), platform channels, and native integrations.
• Shipped at least one app to the App Store / Play Store and iterated based on real user feedback.
• Deep understanding of mobile performance widget rebuilds, isolates, rendering optimisation, and memory profiling.
• Good product instinct: you question user flows, not just implement them.
• Comfortable working with AI coding tools (Cursor, Claude Code) to move fast.

Bonus:

• Experience building custom render objects or complex animations in Flutter.
• Built conversational or generative UI (streaming responses, dynamic component rendering).
• Familiarity with Flutter's platform view integration and method channels for native SDKs.
