We are not just another fintech unicorn. We are a pack of dreamers, makers, and tech enthusiasts building the future of payments. With millions of happy customers and a hunger for innovation, we're now expanding our neural network - literally and metaphorically.

This is not your typical mobile dev role. We're looking for innovative engineers who can transform complex payment flows into seamless mobile experiences. Whether you're experienced with Flutter's widget system, passionate about state management patterns, or skilled in building high-performance cross-platform apps - if you dream in mobile-first solutions and see elegant code as your artistic medium, this is your stage. Our mission needs engineers who don't just write code, but craft experiences that millions of users will carry in their pockets.

What you will be doing:

  • Build, test and deploy new user-facing code in Dart for Flutter technology
  • Craft trustworthy user experiences
  • Investigate and fix problems, alongside performance and scalability issues
  • Assist in planning, estimation, and scoping of feature development
  • Review pull requests from other software engineers (eventually pair programming with them)

What You Need To Succeed:

  • Relevant experience with mobile app development using Dart language and the Flutter Framework
  • Have the "Clean code" (from Uncle Bob) as his bedside book
  • Structures his code following the clean architecture 
  • Applies the SOLID principles every day
  • Deep understanding of state control patterns such as BloC, MobX, and Provider
  • Experience developing Unit Tests, and Integration tests in Flutter
  • Successfully developed and deployed a Flutter application to App Store or Google Play
  • Experience with Firebase tools and design tools such as Figma, Avocode or Zeplin
  • Previous experience with mobile app development using native technologies (iOS or Android)
  • Advanced proficiency in AI-driven tools and automation for software development.
  • Exceptional communication skills, with advanced English for effective interaction within our global team.

The Future We See:

At CloudWalk, we envision a future where AI empowers every field to reach new heights:
• People teams leveraging AI to transform talent acquisition and employee development.
• Marketing professionals creating data-driven, AI-powered campaign strategies.
• Customer Success teams enhancing client experiences with intelligent solutions.
• Risk analysts combining human expertise with AI to navigate complexities.
• Designers collaborating with AI to push creative boundaries.


Join us at CloudWalk, where we’re not just engineering solutions; we’re building a smarter, AI-driven future for payments—together.
