About the Job

Requirements

  • An advanced degree (Master's or PhD) in Computer Science, Machine Learning, Robotics, or a related field, or equivalent practical experience.
  • More than five years of hands-on experience developing machine-learning systems in production, ideally in real-time or interactive environments.
  • A strong background in one or more of reinforcement learning, fine-tuning, decision-making under uncertainty, AI planning, or multi-agent systems.

Responsibilities

  • Design, implement, and scale AI agent systems in Unity environments that enable goal-directed behaviour, 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 to perform various tasks for building Unity games.
  • Integrate machine-learning models within real-time game engine constraints, optimizing latency, compute, and determinism.
  • Lead high-impact initiatives, including hierarchical reinforcement learning for scalable behaviours, AI planning and goal inference frameworks for NPCs and simulations, and agent memory and world modelling systems for persistent, believable behaviour.
  • Collaborate across internal and external teams to enable 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 promote 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.

About the Company

Unity

Real-time cross-platform 2D/3D content platform

Unity is a software platform for creating interactive experiences in 2D, 3D, VR, and AR. It provides a real-time development engine and editor that lets users design, build, and publish content across many platforms, including mobile devices, PCs, and consoles. The product works by compiling assets, scripts, and scenes into a live, interactive app that can be exported to different devices; users can iterate in real-time and access cross-platform tools, asset libraries, and services. Unity differentiates itself from competitors with its broad, cross-platform real-time engine, a large ecosystem and marketplace, and a tiered subscription model plus additional support services tailored to individuals, studios, and enterprises. Its goal is to help developers—ranging from hobbyists to large companies—create and deploy interactive content quickly and at scale across multiple industries such as gaming, film, architecture, automotive, and engineering.
