Unity Animation Jobs (NOW HIRING)

The opportunity

What you'll be doing

• Help define runtime protocols, formats, and execution models to encode, compress, and replay interactive 3D content between engines and AI models.
• 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.

What we're looking for

• Core Engine Experience: Experience building or fundamentally extending game engine cores, middleware, or foundational systems (e.g. serialization, build pipelines, memory subsystems).
• 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.
• Architecture & Execution: Ability to design modular, testable systems - then implement, profile, debug, and ship them end-to-end.
• High-Performance Coding:  Strong C++ and C# skills, with practical understanding of CPU caches, memory layout, allocation patterns, branch behavior, profiling, and performance tradeoffs in real-time systems.
• Engine-Wide Breadth: Hands-on experience across multiple engine domains - such as physics, animation, input, rendering, assets, or build systems - and how they interact.

You might also have

• Experience building infrastructure for training data generation, synthetic data, simulation environments, evaluation harnesses, reinforcement learning, or agentic workflows.
• 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
• 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.
