  • Explore and adopt tools or technologies that improve development velocity and quality
  • Help maintain a clean, readable, and scalable mobile codebase

Requirements

  • Experience building mobile applications for iOS, Android, or both
  • Strong experience with Flutter is a significant plus
  • Solid understanding of mobile UI development and user experience principles
  • Familiarity with mobile performance optimization and debugging
  • Understanding of the full mobile development lifecycle
  • Experience writing clean, maintainable, and well-structured code

  • A generous meal card
  • Full visa & relocation support if you’re moving to Barcelona
  • Annual learning & development budget for courses, tools, or events that support your growth
  • Free access to Codeway’s suite of apps across productivity, wellness, and education
