About the Role

We are looking for a Flutter Developer to join our mobile engineering team and take ownership of enhancements and ongoing development of the BigMint mobile application. This is a hands-on role - you will be expected to own features end-to-end, from understanding the requirement and coordinating with the backend team, through to testing, deployment, and post-release monitoring.

The ideal candidate is someone who takes pride in delivering clean, stable, and well-tested mobile experiences - not just writing code but caring about what ships to users.

Key Responsibilities

Application Development & Enhancement

Develop, enhance, and maintain the BigMint Flutter application across Android and iOS platforms.

Build reusable, modular widgets and components that are consistent with the existing design system and UI patterns.

Translate product and design requirements into production-ready Flutter code with minimal handholding.

Identify and resolve performance bottlenecks, UI rendering issues, and crashes proactively.

API Integration & Backend Coordination

Work closely with the backend team to integrate APIs - understand the contract, raise gaps early, and handle edge cases on the mobile side.

Implement robust error handling, loading states, and offline-first or graceful degradation patterns where applicable.

Participate in API design discussions to provide a mobile perspective on data structure and response formats.

Testing & Quality

Write unit tests for all business logic and critical UI components as a standard part of development, not an afterthought.

Perform thorough manual testing across device types and OS versions before raising any PR.

Coordinate with QA for regression testing cycles and actively support bug triage and resolution.

Deployment & Release Management

Manage the end-to-end release process - build signing, versioning, release notes, and submission to Google Play Store and Apple App Store.

Handle review feedback from app stores and resolve compliance or policy issues independently.

Maintain release checklists and ensure deployments follow a structured, repeatable process.

Collaboration & Communication

Participate in sprint planning and provide realistic effort estimates for mobile tasks.

Communicate blockers, dependencies, and risks early - especially around API readiness or third-party SDK changes.

Maintain clear documentation for complex flows, state management decisions, and third-party integrations.

Qualifications & Skills

Experience

2–5 years of hands-on Flutter development with at least one live application on the Play Store or App Store that you personally shipped.

Technical Skills

Strong command of Flutter and Dart - state management, navigation, and widget lifecycle.

Solid understanding of API integration patterns, async/await, and error handling in Flutter.

Experience with unit testing and widget testing in Flutter.

Familiarity with push notifications (FCM), deep linking, and background services.

Experience with Play Store and App Store submission processes - build signing, versioning, release tracks, and review resolution.

Basic understanding of CI/CD for mobile is a plus.

Familiarity with Git and PR-based development workflows.

Business & Soft Skills

Takes ownership - doesn’t wait to be asked to test, document, or raise a risk.

Strong attention to detail in both code quality and user-facing behavior.

Clear communicator - especially in async coordination with backend teams on API contracts.

Comfortable working in a product environment where requirements evolve and priorities shift.
