Role

Who you are

* Advanced degree (MS or Ph.D.) in Computer Science, Machine Learning, Robotics, or a related field—or equivalent practical experience
* 5+ years of hands-on experience developing ML systems in production, ideally within real-time or interactive environments
* Strong background in one or more of the following: reinforcement learning, fine-tuning, decision-making under uncertainty, AI planning, or multi-agent systems

What the job involves

We’re looking for a Senior Machine Learning Engineer to lead the development of these foundational AI systems within the Unity engine, empowering creators to build smarter, more responsive in-game agents and simulations. 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
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

Our take

Unity is one of the biggest names in game development, powering everything from indie hits to blockbuster titles. Its real-time 3D engine gives developers and artists the tools to build rich, interactive worlds that run across mobile, PC, console and beyond.

But Unity's ambitions stretch far beyond gaming and over the past few years, Unity's technology has found a home in industries including automotive, film and television, where companies use it to create digital twins, virtual productions and immersive experiences. Its tools also help power augmented reality experiences on devices from companies such as Apple.

In 2021, Unity was used to create 72% of the top 1,000 mobile games and half of all games released across mobile, pc and console. Since its 2020 IPO, the company has continued to expand its platform, and with significant post-IPO funding secured in 2025, Unity now supports more than 20 platforms, operates in over 190 countries and territories, and is continuing to push real-time 3D technologies into new industries.
