Senior Core Engine Architect

Unity; United States; Remote; USD 136,000 - 204,000; Full time

Job summary

Unity is seeking engineers to invent how real-time 3D runtimes communicate and render under real-world constraints. You’ll work at the intersection of core engine tech, high-performance networking, distributed systems, and graphics.

You’ll own critical engine subsystems, design scalable APIs, optimize timing and resource use, and ensure assets load and synchronize across processes and networks, even when you don’t control the main loop.

Qualifications

• Experience building or extending core engine systems.
• Strong C++ and C# skills with understanding of memory and perf.
• Experience across multiple engine domains (e.g., physics, animation, assets).

Responsibilities

• Own and evolve subsystems across the engine stack from C++ to C# APIs.
• Design and implement high-performance, extensible APIs for embedded, cross-process, and networked configurations.
• Develop schemes to manage execution timing and resource contention across processes and networks.
• Orchestrate loading, change tracking, serialization, and synchronization of components/assets in bandwidth/latency-constrained environments.
