The University of Luxembourg, a leading international research university, is seeking a Postdoctoral Researcher in Artificial Intelligence to join the CLAIM and ICR research groups within the Faculty of Science, Technology and Medicine (FSTM). The successful candidate will contribute to cutting-edge research in Large Language Models, focusing on Agentive Reasoning and LLM orchestration. Responsibilities include conducting state-of-the-art research, contributing to research proposals, assisting in supervision and teaching, and participating in public dissemination activities. Collaboration opportunities with local spin-offs are available. The position requires a PhD in computer science or a related discipline, with experience in normative reasoning, particularly with legal texts. Strong English communication skills, creativity, commitment, and teamwork are essential. The university offers a modern, dynamic, and multilingual environment, with high-quality equipment and close ties to industry and European institutions. The contract is for 24 months, full-time, with a gross annual salary of EUR 85,176. The position is based at Campus Belval, with a planned start date in September 2025. Applicants should prepare a CV, cover letter, thesis abstract, list of three referees, and a description of research interests/ideas, and apply online through the university's HR system. Early applications are encouraged, and the university promotes an inclusive and respectful culture for all employees and students.

The University of Luxembourg invites applications for a Postdoctoral Fellow in Child-Safe Multi-Agent AI, based at the Belval Campus within the Faculty of Science, Technology and Medicine (FSTM). The position is embedded in the Department of Computer Science and the Interdisciplinary Lab for Intelligent and Adaptive Systems (ILIAS), specifically within the Research Group for Individual and Collective Reasoning (ICR) led by Professor Dr. Leon van der Torre. The AI4KIDS project aims to advance child-centric safe AI by developing a norm-first Belief-Desire-Intention (BDI) architecture, where generative models (LLMs) are constrained by machine-readable child-protection policies to ensure purposeful, legally compliant, explainable, and auditable AI behaviour. Research will focus on embedding explicit norms into the BDI cycle, compiling enforceable policy-as-code for real-time safety checks, parameter-efficient fine-tuning of LLMs for age-appropriate and pedagogically meaningful dialogue, and high-performance computing pipelines on Luxembourg's MeluXina supercomputer for large-scale simulation and adversarial testing. The project includes industrial validation with social robotics platforms (such as QTrobot) for deployment in educational and special-needs contexts, integrating computational law, symbolic AI, and large-scale evaluation into a blueprint for safe child-facing AI. The successful candidate will lead high-impact research at the intersection of multi-agent systems, normative architectures, symbolic AI, and safe LLM integration. Responsibilities include designing and implementing norm-constrained agent architectures with real-time compliance checking, integrating research outcomes with social robot platforms and simulation environments, disseminating results through scientific publications and presentations, participating in research funding proposal writing, and performing teaching activities at bachelor, master, and PhD levels. The postdoctoral fellow will report to the project coordinator and Principal Investigator for AI4KIDS. Applicants must hold a PhD in Computer Science or related fields (Software Engineering, Artificial Intelligence, Distributed Systems), with a strong research record in multi-agent systems, distributed/adaptive systems, and/or agent-oriented software engineering. Experience or strong interest in normative agent architectures (BDI), safety-by-design AI, and integration with robotic platforms is expected. Familiarity with LLMs and their safe adaptation for restricted domains is a strong asset. Candidates should be team players able to work in an interdisciplinary, international research environment and must be fluent in English. The University of Luxembourg offers a modern, dynamic, and international environment with high-quality equipment and close ties to industry and European institutions. The position is a fixed-term contract for 24 months, with a yearly gross salary of EUR 85,176. The planned start date is June 2026. Applications should be submitted online through the HR system and must include a CV, cover letter, PhD diploma or expected defense date, transcript of university-level courses, publication list, and names/contact details of three referees. Early application is encouraged as applications are processed upon reception. The University promotes an inclusive culture and encourages applications from individuals of all backgrounds.
