  • Contribute to code reviews and uphold engineering standards across projects

What We're Looking For:

  • Strong grasp of mobile app architecture and state management
  • Experience integrating REST APIs and third-party services
  • Ability to work independently in a fully remote environment
  • Good English and Lithuanian communication skills
