Senior Applied Scientist, 3D Reconstruction

Overview

The opportunity:

At Unity, we shape the future of real-time 3D development by enabling creators to harness intelligent, autonomous systems. Our next-generation agentic AI is goal-directed, adaptive, and capable of reasoning and planning in dynamic environments, transforming how games and simulations come to life. We are looking for a Senior Machine Learning Engineer to lead the development of foundational AI systems within the Unity engine for game understanding.

You will translate cutting-edge machine learning research into production-ready systems that improve workflows, recommendations, and in-engine intelligence, enabling creators to build more engaging content and reach targeted audiences.

If you’re excited about advancing AI, multi-modal foundation models, and intelligent decision-making in real-time environments, we encourage you to apply.

• Research, design, and implement the game understanding models.
• Collaborate across internal teams to deliver production use cases.
• Lead end-to-end high-impact initiatives, from data curation and model development to production deployment.
• 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.

• Advanced degree (MS or Ph.D.) in Computer Science, Machine Learning, or a related field.
• 5+ years of hands-on experience developing ML systems, ideally within real-time or interactive production environments.
• Experience with multi-modal foundation models, multi-agent systems, orchestration, or AI tool integration.
• Track record of implementing research in LLM, behavior modeling, reinforcement learning, multi-modal models, or agentic systems.
• Ability to identify promising research directions and turn ideas into working code.
• Proficiency in at least one general-purpose programming language (e.g., Python, C++, Go, Java) and familiarity with ML frameworks (e.g., PyTorch, Tensor Flow).
• Strong system design skills and the ability to architect performant, scalable ML systems.
• Excellent communication and collaboration skills; ability to work with cross-functional teams including ML researchers, game engine developers, designers, and product managers.

• Passion for the gaming industry and AI applications in games.
• Familiarity with game development workflows.
• Experience working on large-scale Ads systems.
• Publications or open-source contributions in LLM, reinforcement learning, agent-based modeling, or related areas.
