Job summary

Unity is seeking engineers to help invent how real-time 3D runtimes communicate and render under real-world constraints. You will work at the intersection of core engine tech, high‑performance networking, distributed systems, and graphics, building the infrastructure for the next generation of interconnected game ecosystems.

You will own critical engine subsystems, design scalable APIs, and optimize performance across C++ and C# code in host environments you don’t control.

Qualifications

• Experience building or fundamentally extending game engine cores.
• Strong C++ and C# skills with practical understanding of memory layout and profiling.
• Hands-on experience across multiple engine domains (physics, animation, input, assets).

Responsibilities

• Own 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.
