Game Engine / 3D Developer (Godot)

About the role

Rapsodo, a global sports technology company, develops data-driven sports analytics products combining computer vision, AI, hardware and cloud technologies. As a Game Engine / 3D Developer, you will develop and optimize 3D golf games built with Godot 4 and C# within a Kotlin Multiplatform mobile application, delivering high-quality visuals and smooth performance on iOS and Android while keeping a clean, testable architecture. You will also work with AI-assisted development tools.

Key responsibilities

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

Required profile

• 5+ years of professional Unity development experience with C#; Godot experience is a plus but not required.
• Experience shipping at least one mobile 3D project.
• Strong understanding of 3D mathematics (vectors, quaternions, transformations, coordinate systems).
• Experience with technical art, lighting, post-processing, terrain, vegetation, shaders and materials.
• Hands-on experience with mobile GPU profiling tools such as Xcode GPU Frame Capture or Android GPU Inspector.
• Experience debugging iOS and Android builds, with familiarity with Git, shell scripts, command-line tools and headless builds.
• Practical experience with AI coding tools such as Claude Code, Cursor or GitHub Copilot.

Required skills

• C# with clean architecture, engine-independent logic and unit testing.
• HLSL, Shader Graph or GLSL, able to adapt shaders across engines.
• Nice to have: Godot 4 and C#, native mobile development (Android plugins with Kotlin/Java, iOS with Swift/Objective-C, or Unity as a library), and procedural mesh generation, GIS or elevation data.
