United Kingdom · Full-time · Mid-Senior

Senior Flutter Developer | Global SaaS | 5M+ Users (Scale-up)


Company | Role intro


We aren’t just building an app; we are building a global gateway. Our platform is currently utilized by over 5 million users worldwide, and with our user base growing by 250,000 every single month, the stakes have never been higher.


As we continue to grow, we are currently looking for a Flutter Developer to join our award-winning team (we’ve been recognized globally for our product and culture) within our Onboarding & Customer Portal Team. This is the heartbeat of our user journey, the very first touchpoint for every new member of our community and the hub they return to daily.



What's the role and what will you do?


You will be responsible for crafting a world-class mobile experience that makes "joining us" as seamless as "using us." Working at the intersection of high-fidelity UI and complex backend integration, you will ensure that whether a user is in London, Sydney, or New York, their first experience with our platform is flawless.


Day-to-day:


  • Scale the Experience: Develop and maintain high-performance mobile features using Flutter for a global audience of millions.
  • Master the Onboarding Journey: Build, test, and optimize the customer portal and onboarding flows, ensuring a frictionless transition from "curious visitor" to "active user."
  • Cross-Platform Excellence: Ensure our codebase delivers a consistent, high-quality experience across both iOS and Android.
  • Collaborate & Innovate: Work in a high-performing squad alongside designers and product managers to turn complex onboarding requirements into simple, elegant code.
  • Quality at Speed: Participate in a "multi-award-winning" engineering culture that prizes clean code, automated testing, and rapid deployment.



We're currently looking for an experienced Mobile Applications Developer, with a real passion for building amazing customer experiences and who can offer the following:


  • Flutter Expertise: You have a deep understanding of the Flutter framework and Dart. You know how to build custom widgets and manage complex state (BLoC, Provider, Riverpod, etc.).
  • Mobile-First Mindset: You understand the nuances of mobile performance, from smooth animations to offline-first capabilities.
  • Growth Thinking: You are excited by the challenge of 250k new users a month. You build for scale and think about how code performs under pressure.
  • UI/UX Sensitivity: You have an eye for detail and care deeply about the "feel" of an app—especially during the critical onboarding phase.
  • Collaborative Spirit: You thrive in an "amazing culture" where feedback is a gift and knowledge sharing is the norm.



Ready to lead the portal for millions?


If you’re a Flutter enthusiast who wants to work on a product that is literally changing the face of its industry, we want to hear from you.
