The role involves maintaining and extending a legacy Objective-C + Cocos codebase, optimizing performance, and shipping features in a live-service mobile game environment. Engineers will use AI-assisted workflows and collaborate with cross-functional teams to enhance the game's 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
