Valencia / hybrid model with regular presence in the lab 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.

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/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 partners.

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. Strong programming foundation in Python.

Basic knowledge of APIs,



backend development, or software architecture. Interest in developing an applied PhD. Holding an official master’s degree, or being close to completing one, that qualifies the candidate to pursue a PhD in Spain.

C1 level of spoken and written English to work within the framework of a European project.

Experience with FastAPI, WebSockets, REST APIs, or microservice architectures. Knowledge of Docker, basic deployment, or DevOps tools. Knowledge of Unity, C#, OpenXR, or XR systems integration. Interest in digital twins, simulation, or industrial environments.

Previous experience in research projects, publications, a technical master’s thesis, or personal repositories. This position may be especially interesting if you believe that the future of software engineering will involve systems in which AI agents interact with tools, documentation, sensors, simulations, and complex industrial or clinical environments. We are not looking for a senior profile.

Contract & Outstanding Work-Life Balance: A 3-year contract with adaptable hours and 1 day of remote work per week.

PhD & Career Development: The opportunity to pursue an applied PhD linked to the project, actively participating in scientific publications, international conferences, and technological developments with real-world transfer potential. Top-Tier Research & Network: You will work with the latest XR and AI tools within a European R&D; project, collaborating alongside high-level partners in industrial and healthcare contexts.
