Senior AI Integrations Engineer

The opportunity

What youll 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 were 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.
