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 to build the infrastructure for interconnected game and 3D ecosystems.

You’ll own critical tech enabling Unity to run as a guest within other processes and engines. This deep engine work covers execution models, serialization, asset lifecycles, and runtime

Qualifications

• Experience building or extending game engine cores and foundational systems.
• Ability to design modular, testable systems and implement end-to-end.
• Strong C++ and C# skills with understanding of CPU caches, memory layout, and profiling.
• Experience across multiple engine domains (physics, animation, input, assets).

Responsibilities

• Own and evolve 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.
