Human Tech Institute – Universitat Politècnica de València Location: Valencia / hybrid model with regular presence in the lab Expected start date: Junior / Ph D Track At Lab LENI, part of the Human Tech 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. Habilidades, experiencia, cualificaciones... This position is intended for someone who wants to grow technically and develop an applied Ph D 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. You will participate in the design, development, and integration of prototypes related to: Python backends for conversational agents, AI services, and dynamic tools. 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/Open XR 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 partners.



Profile we are looking for This position may be especially suitable for someone who is finishing or has recently completed a master's degree in areas such as: Software Engineering. Data Science.

Main requirements Strong programming foundation in Python. Basic knowledge of APIs, backend development, or software architecture. Holding an official master's degree, or being close to completing one, that qualifies the candidate to pursue a Ph D in Spain.
