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.

Experience Qualifications & Skills

• 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.
