Senior Core Engine Engineer - Remote

Overview

The team that brought Unity to visionOS and enabled real-time interaction via Play-to-Device is growing in preparation for something even more ambitious: adapting PolySpatial to stream Unity content into other game engines and 3D environments—in-process, cross-process, and over the network. We’re looking for engineers eager to help us invent how different 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.

In Short

• Implement and extend key subsystems across the game engine stack, from low-level C++ engine integrations to high-level C# APIs.
• Profile and optimize execution timing and resource contention within or between processes.
• Improve loading, change tracking, serializing, and synchronizing components and assets.
• Refactor engine code into decoupled modules suitable for embedding and shared execution.
• Develop or heavily modify game engine cores and middleware.
• Utilize solid C++ and C# skills for real-time optimization.
• Jump into unfamiliar areas like physics integration and serialization bugs.
• Have technical experience in engine areas such as physics, animation, or input.
• Experience with WASM, embedded runtimes, or compiler pipelines is a plus.
• Understanding of multithreading and networking concepts is beneficial.

Requirements

• Game Engine Experience: Developed or modified game engine cores.
