Job Description:
At Unity, we’re shaping the future of real-time 3D development
by enabling creators to harness intelligent, autonomous systems.
Our next-generation agentic AI - goal-directed, adaptive, and
capable of reasoning and planning in dynamic environments - is
transforming how games and simulations come to life. We’re looking
for a Staff 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. What youll be doing • Design, implement,
and scale AI agents that assist in generating game code and
executing goal-directed behaviors. • Define orchestration logic for
single- and multi-agent systems • Develop reusable agentic
frameworks - planning modules, memory systems, or policy adaptation
layers - for creator extensibility. • 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. What were looking for • Advanced degree (MS or Ph.D.) in
Computer Science, Machine Learning, or a related field. • 5 years
of hands-on experience developing ML systems in production, ideally
within real-time or interactive environments. • Experience with
multi-agent systems, orchestration, or AI tool integration. •
Strong background in one or more of the following: LLM,
reinforcement learning, decision-making under uncertainty, AI
planning, or multi-agent systems. • Proficiency in at least one
general-purpose programming language (e.g., Python, C++, Go, Java)
and familiarity with ML frameworks (e.g., PyTorch, TensorFlow). •
Strong system design skills and the ability to architect
performant, scalable ML systems. • Excellent communication and
collaboration skills; ability to work effectively with
cross-functional teams including engine developers, designers, and
product managers. You might also have • Familiarity with game
development workflows. • Publications or open-source contributions
in reinforcement learning, agent-based modeling, or related areas.
• Experience with behavior trees, utility AI, or hierarchical task
planning. • Passion for the gaming industry and AI applications in
games. Additional information • Relocation support is not available
for this position.
