OBJECTIVES
We are seeking an experienced Unity Developer to build and evolve RhythmEngine, Amanotes’ internal high-performance, modular engine used across our music games. You will work on core rhythm systems such as audio-time synchronization, tile lifecycle, event flow, scoring, and gameplay foundations that multiple game teams can reuse and extend. If you are passionate about designing reusable gameplay systems, writing clean high-performance code, and creating reliable rhythm mechanics at scale, we want you on our team.
WHAT YOU WILL DO
Develop and enhance RhythmEngine using Unity, focusing on timing, note handling, input judgement, scoring, audio sync, and extensible gameplay modules.
Design and implement modular gameplay systems and clean APIs that allow game teams to integrate, customize, and extend rhythm features efficiently.
Collaborate with game teams to adapt RhythmEngine capabilities to different game modes, content pipelines, and product requirements.
Write clean, high-performance, and maintainable Unity/C# code, and drive code quality through refactoring, code reviews, and engineering standards.
Contribute actively to technical solutions and architecture decisions that improve extensibility, testability, and long-term health of the RhythmEngine codebase.
QUALIFICATIONS
5+ years of hands-on experience building games or software, with solid production experience in Unity/C#.
Proven ability to design modular architectures and shared runtime systems, with practical application of SOLID principles and clear separation of concerns.
Strong engineering discipline in naming, refactoring, debugging, and maintaining legacy code without breaking stability or slowing teams down.
Strong performance mindset for real-time systems, with hands-on experience profiling and optimizing CPU, memory, GC allocations, frame time, AOT/JIT constraints, and gameplay bottlenecks in Unity/mobile environments.
Experience designing clean APIs and developer-friendly integration flows, with strong attention to developer experience, defensive programming, extensibility, and long-term maintainability.
NICE TO HAVE
Experience working on rhythm, music, or timing-sensitive gameplay systems.
Experience with H5/web game development using Phaser, Cocos, or Three.js.
