Doctoral researcher in AI Systems University of Luxembourg in Luxembourg

The University of Luxembourg is recruiting a Doctoral researcher in AI Systems within the Interdisciplinary Centre for Security, Reliability and Trust (SnT), a leading research and innovation centre working on secure, reliable, and trustworthy ICT systems and services.

This PhD project is part of a large industrial research collaboration with a major Luxembourgish energy utility. The research focuses on making AI agents reliable, explainable, and governable in a regulated operational environment. The work examines how teams of bounded-expertise agents can coordinate, resolve disagreement, share reasoning under governed conditions, degrade gracefully when components are unavailable, and make machine reasoning understandable to non-technical professionals. The project combines building real systems with empirical evaluation in operational settings, in collaboration with academic and industrial partners.

The doctoral researcher will join the UBIX Research Group led by Prof. Raphaël Frank. Tasks include carrying out research in the predefined areas, disseminating results through scientific publications, interacting with project and industrial partners, reporting results, and implementing and evaluating proof-of-concept software tools, with open-source release where possible.

Eligible backgrounds include Computer Science or a related engineering discipline. The ideal candidate should have experience or strong interest in large language models and LLM-based agents, multi-agent systems, explainability and interpretability, software architecture and distributed systems, knowledge representation and reasoning, evaluation of LLM-based systems, human-computer interaction, and trustworthy AI / AI governance / regulation. Strong programming skills in Python and C/C++ are required. English at C1 level is required, and French, German, or Luxembourgish at B1 level is an advantage. Applicants must also demonstrate at least B2-level proficiency in the language of their thesis.

Funding: This is a full-time fixed-term doctoral contract for 36 months with a yearly gross salary of EUR 44,531.

How to apply: Submit your application online via the university HR system only. Email applications will not be considered. Include a CV with degree details, thesis title and summary, publication list if available, a GitHub link if available, a cover letter, and transcripts of university-level courses. Early application is encouraged because applications are processed as they are received.

Location: Kirchberg Campus, University of Luxembourg, Luxembourg.
