  • Support the evolution of internal tools and development workflows
  • Identify technical risks early and propose solutions to keep projects on track
  • Ensure cross-platform compatibility and consistent behavior across devices and browsers

What We're Looking For

  • Proven experience in HTML5 game development with a strong portfolio of shipped projects
  • Ability to deliver reliable, maintainable code within agile timelines
  • A proactive mindset—someone who looks beyond assigned tasks to contribute ideas and improvements
  • Strong problem-solving skills, particularly in debugging, performance tuning, and code refactoring
  • Comfort working in a multidisciplinary team with shared goals and iterative delivery

Preferred Background

  • Experience integrating games with major digital platforms such as Netflix, Discord, Facebook, or Microsoft Play
  • Work on titles based on well-known intellectual properties

Work Environment
