Build and evolve Unity’s core engine subsystems powering real-time 3D experiences and device connectivity. You’ll design extensible, high-performance C++/C# systems for embedded and cross-process execution, asset loading and synchronization, and networked configurations. Work end-to-end on serialization, execution timing, resource contention, and runtime performance in host environments Unity doesn’t control, shaving latency and milliseconds where it matters.

Workplace: Remote
Employment Type: Full time
Job Function: Solutions Engineering & Sales Engineering
Seniority: Mid level

Key Responsibilities

  • •Own and evolve critical subsystems across the engine stack, from low-level C++ to high-level C# editor, build, and runtime APIs.
  • •Design and implement high-performance, extensible APIs for embedded, cross-process, and networked configurations.
  • •Develop execution timing and resource contention schemes across processes and over the network with minimal overhead.
  • •Orchestrate loading, change tracking, serialization, and synchronization of components and assets under bandwidth and latency constraints.
  • •Design systems to load, run, and synchronize assets when Unity doesn’t control the main loop, iterating on clean and extensible architecture.

Key Requirements

  • •Experience building or extending game engine cores, middleware, or foundational systems such as serialization, build pipelines, and memory subsystems.
  • •Design modular, testable systems and implement/debug them end-to-end.
  • •Strong C++ and C# skills with practical understanding of CPU caches, memory layout, and profiling.
  • •Hands-on breadth across multiple engine domains (e.g., physics, animation, input, assets) and how they interact.
