Job summary

Unity is seeking engineers to help invent how real-time 3D runtimes communicate and render in constrained environments. You’ll own subsystems from low-level C++ to high-level C# APIs across editor, build, and runtime code, delivering high-performance, extensible architecture.

Ideal candidates have strong C++/C# skills, experience with engine cores, and a passion for performance, serialization, and asset lifecycles in host environments you don’t control.

Qualifications

• Experience building or extending game engine cores, middleware, or foundational systems (serialization, etc.).
• Design modular, testable systems, then implement and debug end-to-end.
• Strong C++ and C# skills with understanding of CPU caches, memory layout, and profiling.

Responsibilities

• Own and evolve critical subsystems across the engine stack, from low-level C++ to high-level C# APIs across editor, build, and runtime code.
• Design and implement high-performance, extensible APIs for embedded, cross-process, and networked configurations.
• Develop schemes to manage execution timing and resource contention within or between processes and over the network with minimal overhead
• Orchestrate loading, change tracking, serializing, and synchronizing components and assets in bandwidth and latency-constrained environments.
