Summary: This role is for an experienced mobile game engineer to evolve a high-performing live game using Objective-C and Cocos, focusing on impact and leveraging AI-assisted workflows. Highlights: 1. Work on a live mobile game with existing traction and players 2. Utilize AI tools to accelerate development, debugging, and refactoring 3. Focus on improving and modernizing legacy codebases with real-world impact **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 **Requirements** **What You’ll Do** * Maintain and extend a legacy Objective\-C \+ Cocos codebase * Optimize performance, memory usage, and runtime behavior for mobile * Refactor and modernize systems without breaking live operations * Ship features, events, and improvements in a live\-service environment * Use AI\-assisted workflows (code generation, debugging, refactoring, test creation) to move faster * Collaborate closely with product, design, and analytics to drive impact * Identify quick wins vs. deep tech improvements and prioritize accordingly **What We’re Looking For** * Strong experience with Objective\-C and iOS development * Hands\-on experience with Cocos (Cocos2d\-x or similar) * Experience working on live mobile games or shipped apps * Ability to navigate and improve legacy codebases * Strong understanding of performance optimization (CPU, memory, rendering) * Pragmatic mindset: you know when to refactor vs. ship * Comfortable leveraging AI tools (e.g., Copilot, ChatGPT, etc.) as part of your workflow **Nice to Have** * Experience with C\+\+ (common in Cocos\-based systems) * Familiarity with game loops, rendering pipelines, and animation systems * Experience migrating legacy systems to modern architectures * Exposure to analytics\-driven development (A/B testing, live ops) **Benefits** * Market competitive, tax\-free USD salaries * Paid Time Off * Performance Bonus * Annual Performance Reviews
