We develop data-driven sports analytics products that combine computer vision, AI, hardware, and cloud technologies to help athletes measure, understand, and improve their performance.
Our products deliver accurate, real-time performance insights in demanding environments, supporting professional athletes, coaches, and sports organizations around the world.
At Rapsodo, engineers take ownership from concept to production, working across multidisciplinary teams to build innovative products that transform complex motion into actionable insights at global scale.
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.
