Unity SDK Developer

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.
