About the Role

IRISS is seeking an experienced and highly motivated Mobile Developer (Flutter) to join our E Sentry Systems team in Bengaluru, India.

This position will play an important role in designing, developing, and maintaining high-quality applications across Android, iOS, and Flutter Web platforms.

Our applications support industrial technicians in commissioning sensors, conducting inspections, and monitoring critical asset data, often in environments with limited or no network connectivity.

The ideal candidate is a hands-on Flutter developer with strong Dart programming skills, experience building production-ready mobile applications, and the ability to troubleshoot native Android and iOS functionality.

You will collaborate closely with firmware engineers, backend developers, product managers, and UI/UX designers to develop reliable, scalable applications that integrate with connected hardware and industrial monitoring technologies.

This is a hands-on development role requiring ownership of application features from initial design and implementation through testing, deployment, and post-release support.

Offline Functionality & Data Management

- Develop offline-first application workflows that operate reliably with limited or unavailable network connectivity.

- Implement local data persistence using SQLite, Drift, Isar, Hive, or comparable technologies.

- Develop synchronization mechanisms that maintain data integrity and resolve conflicts when connectivity is restored.

- Integrate REST APIs, authentication mechanisms, token refresh, secure credential storage, and reliable network communication.

- Implement appropriate error handling, retries, backoff strategies, and security measures.

Android, iOS & Flutter Web Development

- Develop and troubleshoot platform-specific functionality using Kotlin for Android and Swift for iOS.

- Implement Flutter platform channels and native plugins when required.





- Resolve platform-specific challenges involving application lifecycle events, permissions, background execution, and memory management.

- Manage Android build configurations, Gradle, R8/ProGuard, and platform-specific dependencies.

- Support iOS provisioning, signing, entitlements, CocoaPods, Swift Package Manager, and App Store requirements.

- Develop and optimize Flutter Web applications, including navigation, deep linking, browser compatibility, rendering performance, and initial load times.

Testing, Deployment & Application Performance

- Develop and maintain unit, widget, golden, integration, and end-to-end automated tests.

- Conduct testing across supported devices, operating systems, and web environments.

- Maintain application build configurations, signing, release pipelines, and deployment processes.

- Support Google Play Store, Apple App Store, and web application releases.

- Implement CI/CD workflows using Codemagic, GitHub Actions, Fastlane, or comparable tools.

- Monitor application stability, crash reports, and production performance.

- Use Flutter DevTools to investigate performance issues, memory leaks, inefficient widget trees, and rendering problems.

- Troubleshoot production defects and implement verified corrective solutions.

Agile Development & Collaboration

- Participate in Agile ceremonies, including sprint planning, daily stand-ups, sprint reviews, and retrospectives.

- Collaborate with product managers, designers, backend developers, firmware engineers, and other technical stakeholders.

- Break development requirements into clearly defined, achievable tasks.

- Participate in code reviews, technical discussions, and architectural decisions.

- Maintain high standards for code quality, documentation, application reliability, and long-term maintainability.

- Communicate development progress, technical challenges, and potential delivery risks.

Required Qualifications

- 3–5 years of professional mobile application development experience, including at least 3 years developing and delivering Flutter applications into production.

- Strong proficiency in Flutter and Dart, including asynchronous programming, streams, futures, isolates, generics, extensions, and null safety.

- Hands-on production experience with both Bloc and Riverpod state management solutions.

- Strong understanding of Clean Architecture, dependency inversion, repositories, use cases, and feature-based application design.

- In-depth knowledge of Flutter's widget, element, and render object trees, rendering lifecycle, widget keys, and performance optimization.

- Strong UI/UX development skills, including responsive layouts, typography, accessibility, animation, and accurate implementation of Figma designs.

- Experience developing and deploying Flutter Web applications.

- Practical Android development and debugging experience using Kotlin, including lifecycle management, permissions, foreground services, WorkManager, and build tools.

- Practical iOS development and debugging experience using Swift, including background execution, provisioning, signing, and native dependencies.

- Experience developing Flutter plugins or platform channels for native device functionality.

- Experience with local databases such as Drift/SQLite, Isar, or Hive, including schema management and migrations.

- Strong experience integrating REST APIs, authentication systems, secure storage, and reliable networking.

- Experience with automated Flutter testing frameworks such as flutter_test, Mockito, Mocktail, bloc_test, golden_toolkit, alchemist, or integration_test.

- Experience implementing and maintaining CI/CD pipelines using Codemagic, GitHub Actions, Fastlane, or comparable tools.

- Experience profiling and optimizing application performance using Flutter DevTools.

- Familiarity with navigation frameworks such as go_router or auto_route, including deep linking and push notifications.

- Experience with dependency injection using get_it, injectable, Riverpod providers,



or comparable solutions.

- Experience working in Agile or Scrum development environments.

- Strong analytical thinking, debugging capabilities, and problem-solving skills.

Preferred Qualifications

- Experience developing applications that integrate with Bluetooth Low Energy (BLE), NFC, sensors, or connected hardware devices.

- Familiarity with industrial IoT applications, device commissioning, or asset monitoring technologies.
