HumanTech Institute – Universitat Politècnica de València
Location: Valencia / hybrid model with regular presence in the lab
Expected start date: October 2026
Approximate salary: €25k gross/year
Position type: Junior / PhD Track
At LabLENI, part of the HumanTech Institute at the Universitat Politècnica de València, we are looking for a junior profile with a solid technical background in software engineering, artificial intelligence, or interactive systems to join the European project VICTOR-XR, focused on conversational agents, virtual humans, XR, and digital twins.
This position is intended for someone who wants to grow technically and develop an applied PhD at the intersection of LLM agents, software architectures, human-AI interaction, virtual humans, digital twins, and XR environments.
The project will develop a platform in which users will be able to interact by voice with virtual human avatars integrated into XR environments. These avatars will act as cognitive co-pilots capable of interpreting context, connecting with external tools and systems,



providing explainable assistance, and adapting their responses to the user’s state and the task at hand.

What you will do
You will participate in the design, development, and integration of prototypes related to:
Python backends for conversational agents, AI services, and dynamic tools.
Integration of generative models and LLM agents into real-time interaction workflows.
Definition of tools for LLM agents, tool calling, and MCP-like architectures.
Design of APIs and services to connect users, agents, sensors, digital twins, and XR environments.
Integration of the co-pilot with virtual human avatars and Unity/OpenXR environments.
Development of explainable, controlled, and safe dialogue mechanisms for industrial and healthcare contexts.
Integration with multimodal signals such as voice, interaction data, sensors, or user-state indicators.
Deployment, testing, and validation of prototypes in collaboration with European
