What you'll do

• Architect and build the app from the ground up on iOS and Android using Flutter and Dart.
• 
  
• Own it end-to-end — architecture, code, releases, performance, and quality.
• 
  
• Design for scale with a clean, modular, layered architecture.
• 
  
• Optimize for performance, startup time, app size, and memory.
• 
  
• Integrate REST APIs, push notifications, analytics, and crash reporting.
• 
  
• Build automated tests — unit, widget, and integration — as part of how you ship.
• 
  
• Instrument for observability (crash-free rate, ANR, performance) and act on it.
• 
  
• Own releases: CI/CD, signing, staged rollouts, feature flags, and monitoring.
• 
  
• Partner with backend on API contracts, and with design on polish.
• 
  
• Apply fintech-grade security — secure storage, cert pinning, safe token handling.

What we're looking for

• 2+ years building production mobile apps, strong in Flutter and Dart.
• 
  
• At least one app live on the Play Store and/or App Store.
• 
  
• Solid CS fundamentals — data structures, algorithms, design patterns.
• 
  
• Degree in CS or related field, or equivalent practical experience.
• 
  
• Deep grasp of Flutter internals (widget tree, rendering, profiling with DevTools).
• 
  
• Strong Dart — async/await, Futures, Streams, isolates, null safety.
• 
  
• Hands-on with structured state management (Bloc, Riverpod, or Provider).
• 
  
• Comfortable with clean/layered architecture and dependency injection.
• 
  
• Experience with REST networking (Dio, Retrofit), auth, caching, error handling.
• 
  
• Familiar with native iOS/Android builds, signing, and platform channels.
• 
  
• Strong testing instincts and clean, disciplined Git workflow.

Nice to have

• Fintech, payments, banking, or wallet experience (PPI, cards, UPI).
• 
  
• Mobile CI/CD (Fastlane, GitHub Actions, Codemagic, Bitrise).
• 
  
• Firebase (Crashlytics, Analytics, Remote Config, Push).
• 
  
• Offline-first design and local storage (Hive, Drift, SQLite).
• 
  
• Biometric auth, A/B testing, feature-flagged rollouts.
• 
  
• A feel for motion and craft (Rive, Lottie, custom painters).
• 
  
• Accessibility and internationalization by default.
• 
  
• Early/founding mobile engineer at a startup.
