What You’ll Be Doing

• Leading Flutter projects and mentoring team members
• Designing testing strategies across unit, widget, integration, and E2E layers

• Contributing to the Flutter community

What You’ll Need

• Strong Flutter and Dart experience
• Expertise in testing best practices and automation
• Familiarity with CI tools and mobile pipelines
• Ability to solve complex problems with clean, maintainable code
