Job description


About Us
At UserWise Services, we build and scale mobile games played by millions worldwide. Our focus is simple: move fast, deliver impact, and use modern tools—including AI-assisted workflows—to accelerate development and iteration.
We’re now looking for engineers who enjoy reviving, scaling, and modernizing high-adoption live games.

The Role
You’ll work on a proven, high-performing mobile game built with Objective-C and Cocos, helping evolve it for the next stage of growth.
This is not a “build from scratch” role—it’s about:

  • Improving a live product with real users
  • Making smart, high-leverage technical decisions
  • Using AI tools to accelerate development, debugging, and refactoring

Why This Role Is Interesting

  • Work on a game that already has traction and players
  • See your impact immediately in a live environment
  • Use AI as a force multiplier, not just a buzzword
  • Solve real engineering problems—not just greenfield abstractions



Who This Is For

  • Engineers who enjoy fixing, improving, and evolving real products
  • People who like high ownership and fast execution
  • Builders who prefer impact over perfection
