Your work will directly drive innovation, allowing developers and designers to integrate sophisticated AI behavior seamlessly into their worlds. This role is perfect for someone passionate about pushing the boundaries of AI, multi-agent systems, reinforcement learning, and intelligent decision-making in complex, real-time environments. What you'll be doing * Design, implement, and scale AI agent systems in Unity environments that enable goal-directed behavior, task planning and execution, and environment-aware decision-making. * Develop reusable agentic frameworks - such as planning modules, memory systems or policy adaptation layers - that creators can extend in their own projects. * Develop AI models for the Unity AI agentic system. The AI models perform various tasks for building Unity games. * Integrate Machine Learning models seamlessly within real-time game engine constraints, optimizing for latency, compute, and determinism. * Lead high-impact initiatives, including hierarchical reinforcement learning for scalable behaviors, AI planning and goal inference frameworks for NPCs and simulations, and agent memory and world modeling systems for persistent, believable behavior. * Collaborate across internal and external teams to unlock innovative use cases in gaming, simulation, and interactive storytelling. * Contribute to the long-term vision and roadmap for Unity's agentic AI offerings, ensuring modularity, usability, and performance across platforms. * Establish and champion best practices for model quality, simulation-based evaluation, and ML/AI safety within real-time systems. * Mentor engineers and researchers while cultivating a technical culture of innovation, excellence, and collaboration. ## Related Videos - [Introduction to Azure Machine Learning](https://www.wearedevelopers.com/videos/368-introduction-to-azure-machine-learning) - [Building a fully automated escape room](https://www.wearedevelopers.com/videos/735-building-a-fully-automated-escape-room) - [Psychological Safety in Software Engineering - Jenny-Margrethe Vej & Alexandra Hou Aldershaab](https://www.wearedevelopers.com/videos/2142-psychological-safety-in-software-engineering-jenny-margrethe-vej-alexandra-hou-aldershaab) - [What non-automotive Machine Learning projects can learn from automotive Machine Learning projects](https://www.wearedevelopers.com/videos/397-what-non-automotive-machine-learning-projects-can-learn-from-automotive-machine-learning-projects) - [How Machine Learning is turning the Automotive Industry upside down](https://www.wearedevelopers.com/videos/61-how-machine-learning-is-turning-the-automotive-industry-upside-down) - [Coding an Immersive Copilot using Unity / .NET and Azure OpenAI!](https://www.wearedevelopers.com/videos/1204-coding-an-immersive-copilot-using-unity-net-and-azure-openai) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [How Much Does a Software Engineer Make?
