About the Role

As a Game Engine / 3D Developer, you will develop and optimize 3D golf games built with Godot 4 and C# within Rapsodo's Kotlin Multiplatform mobile application. You will focus on delivering high-quality visuals and smooth performance on iOS and Android devices while maintaining a clean, testable architecture. Working with AI-assisted development tools, you will contribute to both game engine development and mobile integration.

What You'll Do

• Develop and maintain 3D golf games using Godot 4 and C# within a Kotlin Multiplatform mobile application.
• Improve visual quality through lighting, materials, shaders, terrain, vegetation, and camera techniques.
• Profile and optimize performance on mobile devices, focusing on GPU usage, draw calls, batching, LODs, and texture budgets.
• Maintain integration between the game engine and mobile application, including Android plugins, iOS hosting, and JSON-based communication.
• Separate game logic and physics into engine-independent, testable .NET libraries and maintain code quality through unit testing.
• Debug iOS and Android builds, analyze device logs, and support reliable deployment across mobile platforms.
• Use AI coding tools in daily development, critically review generated code, and maintain clear architecture documentation and handoff notes.

What We're Looking For

• 5+ years of professional Unity development experience using C#; Godot experience is a plus, not a requirement.
• Experience shipping at least one mobile 3D project.
• Strong understanding of 3D mathematics, including vectors, quaternions, transformations, and coordinate systems.
• Experience with technical art, lighting, post-processing, terrain, vegetation, shaders, and materials.
• Knowledge of HLSL, Shader Graph, or GLSL, with the ability to adapt shaders across engines.
• Hands-on experience with mobile GPU profiling and optimization tools, such as Xcode GPU Frame Capture or Android GPU Inspector.
• Strong C# skills, including clean architecture, engine-independent logic, and unit testing.
• Experience debugging iOS and Android builds, with familiarity with Git, shell scripts, command-line tools, and headless builds.
• Practical experience using AI coding tools such as Claude Code, Cursor, or GitHub Copilot, with the ability to evaluate and improve their output.

Nice to Have

• Experience with Godot 4 and C#.
• Native mobile development experience, including Android plugins with Kotlin/Java, iOS with Swift/Objective-C, or Unity as a Library.
• Experience with procedural mesh generation, GIS, or elevation data.
