Senior Flutter Developer

Daxko builds the software that powers fitness, wellness, and community organizations—everything from member management and payments to digital engagement and analytics. From small studios to the largest associations, we help thousands of fitness businesses streamline operations, enhance member experiences, and drive sustainable revenue growth.

You'll join Grip Technologies Pvt. Ltd., a Daxko subsidiary, working on FitnessForce, the club management platform used by gyms and fitness businesses around the world.

About The Role

FitnessForce's mobile ecosystem includes two apps: a whitelabeled member app for bookings, subscriptions, and workout tracking, and a business app that runs daily club operations for staff. As a senior Flutter developer, you'll own both, building secure, high-conversion mobile experiences that sync in real time with our .NET Core backend.

You'll use AI coding tools like Cursor to move faster, while keeping the codebase clean, performant, and maintainable across iOS and Android.

What You'll Do

• Architect and maintain a single codebase that powers dozens of regional whitelabel clients, managing build-time flavor configurations through CI/CD pipelines like Fastlane
• Integrate secure payment SDKs such as Stripe, building Apple Pay and Google Pay checkout flows for retail purchases and subscriptions
• Drive feature delivery across both the member app and staff app, working through complex logic for POS, multi-club access, and real-time scheduling
• Implement Clean Architecture and state management patterns like Bloc or Riverpod to handle complex, asynchronous UI states
• Manage network layers with Retrofit and maintain reliable code-generation workflows for stable, conflict-free builds
• Champion automated testing across unit, widget, and integration levels to keep releases reliable
• Profile and optimize app performance for large datasets, keeping rendering smooth and memory use efficient across devices
  
  

• 6 to 8 years of software engineering experience, including at least 4 years with Flutter and Dart in production
• Experience building multi-tenant or white labeled mobile apps from a single codebase, with familiarity deploying to the App Store and Google Play
• Hands-on experience integrating native payment SDKs and mobile wallets, including handling 3D Secure authentication and transaction errors
• Experience using AI coding assistants in production, with the Dart and Flutter fundamentals to keep AI-assisted code performant and maintainable
• Strong understanding of mobile system design, state management, and dependency injection
• Working knowledge of native iOS (Swift or Objective-C) and Android (Kotlin or Java) for platform channels and native integrations
  
  

• Experience in the fitness, wellness, or club management software industry
• Understanding of event-driven backend architectures like Kafka, to align mobile caching with backend data streams
