[Remote] Senior AI Integrations Engineer

Note: The job is a remote job and is open to candidates in USA. Unity is the leading platform to create and grow games and interactive experiences. They are seeking a Senior AI Integrations Engineer to help define runtime protocols and build systems for interactive 3D content across various platforms, focusing on integrating AI-driven tools and systems.ResponsibilitiesHelp define runtime protocols, formats, and execution models to encode, compress, and replay interactive 3D content between engines and AI modelsOwn 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 playbackBuild systems to capture, serialize, stream, and synchronize scene state, components, assets, user interactions, and rendering data under tight bandwidth, latency, determinism, and memory constraintsDesign interfaces and feedback loops that allow AI systems to inspect engine state, invoke engine capabilities, and validate outcomesSkillsExperience building or fundamentally extending game engine cores, middleware, or foundational systems (e.g. serialization, build pipelines, memory subsystems)Practical experience integrating AI/ML into production software, including areas such as model training, data collection, evaluation loops, agents, tool use, or model-context protocolsAbility to design modular, testable systems - then implement, profile, debug, and ship them end-to-endStrong C++ and C# skills, with practical understanding of CPU caches, memory layout, allocation patterns, branch behavior, profiling, and performance tradeoffs in real-time systemsHands-on experience across multiple engine domains — such as physics, animation, input, rendering, assets, or build systems — and how they interactExperience building infrastructure for training data generation, synthetic data, simulation environments, evaluation harnesses, reinforcement learning, or agentic workflowsFamiliarity with 3D data formats and spatial content pipelines, such as USD, glTF, procedural generation, or semantic scene representationsExperience with MCP-style tool interfaces, LLM agents, multimodal models, inference pipelines, embeddings, vector search, or AI systems that inspect and act on structured application stateKnowledge of compression, streaming, replication, authority models, RPCs, state diffing, delta encoding, or network protocols for real-time interactive systemsExperience with determinism, replay systems, simulation consistency, multithreading, job systems, lock-free programming, Unity DOTS, or other data-oriented runtime architecturesBenefitsComprehensive health, life, and disability insuranceCommute subsidyEmployee stock ownershipCompetitive retirement/pension plansGenerous vacation and personal daysSupport for new parents through leave and family-care programsOffice food snacksMental Health and Wellbeing programs and supportEmployee Resource GroupsGlobal Employee Assistance ProgramTraining and development programsVolunteering and donation matching programCompany OverviewUnity [NYSE: U] offers a suite of tools to create, market, and grow games and interactive experiences across all major platforms from mobile, PC, and console, to extended reality.
