Job summary

Qode is seeking a skilled mobile engineer to build production-grade apps for iOS and Android using Flutter and Dart. You will own architecture, code, releases, and performance, delivering a clean, scalable product.

You should have 2+ years of Flutter experience, a live app on stores, strong CS fundamentals, and hands-on with state management, REST APIs, and testing. Join a startup-minded team and help shape fintech-ready mobile solutions.

Qualifications

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

Responsibilities

• 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.
