Job description

Responsibilities

• Jump into the real codebase from day one, not shadow from the sidelines
• Build and ship features across the Flutter app — onboarding, lessons, roleplays, AI voice conversations, feedback flows, and monetization
• Work on real-time voice interactions and the flows that make them feel instant and natural
• Integrate with backend services and APIs, and dig into the backend yourself when needed
• Chase down bugs, crashes, and performance issues, and improve app stability
• Look at funnels, activation, feature usage, and paywalls to understand how your code affects real user behavior
• Test features before they go live, challenge weak UX, question unclear copy, and push for the details that make the product better
• Help ship fast, measure what happened, learn from the results, and move on to the next iteration
• Sometimes you'll work on mobile. Sometimes on backend. Sometimes on QA or performance. Sometimes on things no one has a perfect job title for yet

Requirements

• Highly curious about AI, mobile apps, consumer products, and real‑time voice experiences
• Comfortable building features in Flutter/Dart end to end — UI, state management, and API integration
• Understand how to work with REST/WebSocket APIs, async flows, and app architecture
• Care about performance, smooth UX, and shipping polished, bug‑free builds
• Comfortable reading and touching backend code when a feature demands it
• Proactive, organized, detail‑oriented, and comfortable following up
• Don't wait for step‑by‑step instructions; you look for ways to add value
• Comfortable working with data, logs, crash reports, and product metrics
• Communicate clearly in English
• Bonus if you have: published apps on the App Store / Play Store, experience with real‑time audio, native platform code (iOS/Android), CI/CD, or backend work (Node, Python, Go, etc.).
