About the role
- You'll help invent the protocols, media formats, and runtime systems that bring interactive 3D content to novel platforms.
- Working at the intersection of core engine technology, graphics, networking, distributed systems, media, and AI, you'll help define the interchange layer for the next generation of interconnected games and intelligent 3D ecosystems.
Responsibilities
- Own and evolve critical subsytems across the engine stack, from low-level C++ runtime code to high-level C# APIs across editor, build, simulation, streaming, and playback.
- Build systems to capture, serialize, stream, and synchronize scene state, components, assets, user interactions, and rendering data under tight bandwidth, latency, determinism, and memory constraints.
- Design interfaces and feedback loops that allow AI systems to inspect engine state, invoke engine capabilities, and validate outcomes.
- The team behind Unity's visionOS support, Play-to-Device, and
- Experience building or fundamentally extending game engine cores, middleware, or foundational systems (e.g. serialization, build pipelines, memory subsystems).
- Relocation support is not available for this position
- Unity [NYSE: U] is the leading platform to create and grow games and interactive experiences.
Requirements
- AI Systems Fluency: Practical experience integrating AI/ML into production software, including areas such as model training, data collection, evaluation loops, agents, tool use, or model-context protocols.
- Experience with MCP-style tool interfaces, LLM agents, multimodal models, inference pipelines, embeddings, vector search, or AI systems that inspect and act on structured application state
- Knowledge of compression, streaming, replication, authority models, RPCs, state diffing, delta encoding, or network protocols for real-time interactive systems.
- Experience with determinism, replay systems, simulation consistency, multithreading, job systems, lock-free programming, Unity DOTS, or other data-oriented runtime architectures.
Compensation
- Familiarity with 3D data formats and spatial content pipelines, such as USD, glTF, procedural generation, or semantic scene representations.
- Experience with MCP-style tool interfaces, LLM agents, multimodal models, inference pipelines, embeddings, vector search, or AI systems that inspect and act on structured application state
