Senior Mobile Engineer (Objective-C / Cocos - Live Game Evolution)

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
