Job description

Mobile Front-End Engineer (Flutter), – Mumbai / Hybrid

Department: Marketing

Positions: 2

What is this job about

We're looking for a Flutter engineer who cares about the details — smooth animations, fast startup, screens that behave correctly on a patchy 3G connection. You'll own our mobile applications end to end on the client side: architecture, implementation, performance, release, and the support that follows.

This is a hands-on, front-end-focused role. You'll work alongside backend engineers, product managers, designers, QA, and support, and you'll have real ownership of the mobile architecture rather than just picking up tickets.

Responsibilities

• Design, build, and ship features in Flutter and Dart across Android and iOS.
• Own the mobile architecture: modular, reusable, scalable, and maintainable code that stays that way as the product grows
• Integrate RESTful APIs and manage complex asynchronous data flows reliably, including offline and error states
• Translate designs into responsive, fluid interfaces using Flutter's animation and rendering capabilities.
• Own client-side performance: startup time, rendering, memory footprint, and overall efficiency. Use monitoring tooling to find issues before users do.
• Implement and maintain client-side security controls appropriate for a financial-grade application
• Publish, maintain, and support releases on the Google Play Store and Apple App Store, including staged rollouts and crash triage.
• Contribute across the full software development lifecycle — requirements, design, implementation, code review, testing, release, and support.
• Partner with backend engineers on API contracts, and with designers and QA to ensure both code quality and product quality meet a high bar.

Key Skills

• EDUCATION: BTech / BE (or equivalent) in Computer Science, Engineering, or a related field.
• EXPERIENCE: min.5years (and more) of professional software development experience, with substantial time in Flutter.
• MUST HAVE: Professional working proficiency in English, written and spoken
• MUST HAVE: High level of Ownership, great Work Ethic, with an analytical mindset, Comfortable handling a high volume of work in a fast-paced environment.
• MUST HAVE: Collaborative within a team, and equally effective working independently with moderate supervision.
• MUST HAVE: Need to Care about the craft; clean code, thoughtful reviews, and products that hold up under real-world use.
• CORE SKILLS: Strong hands-on experience with Flutter and Dart
• CORE SKILLS: Deep working knowledge of Clean Architecture, the Repository Pattern, SOLID principles, Dependency Injection, and BLoC/Cubit state management.
• CORE SKILLS: Extensive experience integrating RESTful APIs and handling asynchronous data flows.
• CORE SKILLS: Hands-on experience with local storage: Hive, SharedPreferences, and Flutter Secure Storage
• CORE SKILLS: Solid grasp of mobile security best practices, including JWT authentication, AWS Cognito, SSL pinning, data encryption, and biometric authentication
• CORE SKILLS: Experience with Firebase — Crashlytics, Remote Config, Cloud Messaging (FCM), and Analytics
• CORE SKILLS: Experience implementing Deep Links, Universal Links, and App Links.
• CORE SKILLS: Strong experience integrating native platform functionality via Method/Platform Channels on both Android and iOS.
• CORE SKILLS: Experience building high-performance, responsive UI components and Flutter animations.
• CORE SKILLS: Demonstrated ability to optimise application performance and diagnose issues using monitoring and profiling tools
• CORE SKILLS: Track record of publishing and supporting apps on both major app stores.
• Nice to have SKILLS: Experience in the financial services industry, particularly mutual funds or investment platforms
• Nice to have SKILLS: Experience with widget, unit, and integration testing in Flutter
• Nice to have SKILLS: Experience with CI/CD pipelines for mobile releases (Fastlane, Codemagic, GitHub Actions, or similar)

• Nice to have SKILLS: Working familiarity with backend fundamentals — REST, microservices, and a server-side language such as Java — enough to debug an integration end to end.
