  • Excellent English communication skills, with the ability to clearly share ideas and present solutions in team settings
  • A proactive, collaborative attitude and a passion for solving real customer problems
  • Strong interest in improving technical systems and processes, not just building features
  • Curiosity about AI and regular use of AI tools to enhance your development workflow

  • Ability to design and architect complex web applications and backend systems independently
  • Solid understanding of HTML, CSS, and core JavaScript concepts
  • Experience collaborating with Product Managers and Designers during Product Discovery
