The Digital Character AI team at ETH Zurich's Computer Graphics Laboratory is looking for a Student Research Assistant to support the frontend development of our interactive AI avatar platforms. Our work focuses on lifelike digital humans powered by large language models, affective computing, and real-time rendering - deployed at high-profile events such as the World Economic Forum, Berlin Science Week, and GITEX. You can learn more about the Digital Einstein project
here.
Project background Digital Einstein is an award-winning AI avatar platform that brings Albert Einstein to life as an interactive conversational agent. Built on a Unity-based frontend integrated with speech recognition and real-time facial and body animations, it has been showcased at major international events. The backend is implemented in Python and orchestrates large language models for dialogue management and response generation. We are currently extending the platform to a new Digital Curie installation. As our team scales up, we are looking for a student assistant to primarily help maintain and further develop the Unity frontend for both avatars - with the option to also contribute to the Python/LLM backend.

- Integration and testing of UI components, interaction flows, and real-time rendering elements
- Optionally: support on the Python/LLM backend (dialogue systems, model integration)
- On-site support at events and demonstrations (setup, visitor interaction, troubleshooting)
- Weekly team meetings (1-2 hours) to discuss progress and plan next steps
- Workload: 15 hours/week during semester, up to 41 hours/week during semester breaks (flexible)
Profile - Enrolled student at ETH Zurich or another Swiss university
- Strong hands-on experience with Unity (required)
- Interest in interactive systems or AI-driven applications
- Reliable, proactive, and comfortable working independently as well as in a team
