Key Responsibilities

• Own the technical design, development, testing, release, and ongoing maintenance of mobile game client modules, ensuring reliable, high-quality delivery of requirements.
• Independently implement client systems for core gameplay, UI interactions, and character presentation, working with game designers, artists, and technical artists to refine the player experience.
• Design and maintain a clear, extensible client codebase that supports version updates, in-game events, and long-term live operations.
• Work with server engineers to define APIs, data synchronization, and error handling, and integrate networking features, remote configuration, and analytics reporting.
• Analyze and optimize CPU and GPU performance, memory usage, loading times, and network performance on mobile devices; resolve crashes, stuttering, and device compatibility issues.
• Participate in code reviews, technical design discussions, and incident reviews to improve code quality, test coverage, and delivery efficiency.
• Collaborate with product managers, game designers, QA, and other cross-functional teams to break down technical tasks, identify risks, and drive issues through to resolution.

Requirements

• Bachelor's degree or higher in Computer Science, Software Engineering, or a related discipline, with at least 3 years of game client development experience.
• Proficiency in C# or C++, with project development experience using Unity, Unreal, or a comparable real-time game engine.
• Experience with a released game or a complete project, with the ability to independently own client features from development and integration testing through to release and maintenance.
• Familiarity with common client architectures, data structures, and software design approaches, with the ability to write stable, maintainable, performance-conscious production code.
• Experience in mobile debugging and performance profiling, with an understanding of how device differences, memory, loading, frame rate, and network conditions affect games.
• Strong communication and collaboration skills, with the ability to conduct code reviews, share knowledge, and work effectively with game design, server engineering, QA, and other teams.

Preferred Qualifications

• Experience launching mobile games or supporting long-term live operations, with familiarity with event updates, hot updates, asset package splitting, or remote configuration.
• Experience building gameplay frameworks, UI frameworks, asset loading systems, network synchronization systems, or performance diagnostic tools.
• Practical experience with automated testing, continuous integration, crash monitoring, or AI-assisted development tools.
