OBJECTIVES

We are seeking an experienced Unity Game Developer to build reusable SDK modules and shared runtime systems that can be adopted across multiple products.

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
