[Hiring] Senior Mobile Engineer @UserWise Services

Role Description

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:

• 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

Requirements

• 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

Benefits

• Market competitive, tax-free USD salaries
• Paid Time Off
• Performance Bonus
• Annual Performance Reviews
