Are you excited to shape the next generation of agentic conversational AI systems? If so, please continue reading!
Are you excited to shape the next generation of agentic conversational AI systems? Join us as a postdoctoral researcher in the LESSEN consortium, where you will work on cutting-edge research at the intersection of conversational AI, large language models, multi-agent systems, and intelligent tool use.
Recent advances in AI are shifting toward agentic AI systems, where multiple LLM-based agents interact with tools, environments, and users to solve complex tasks. Studying and assessing such systems presents new challenges beyond traditional benchmarks. In this position, you will investigate methods for benchmarking and studying agentic conversational systems, while contributing to the development of shared resources and experimental frameworks for the LESSEN consortium.
You will become part of a collaborative and ambitious research environment, working closely with PhD researchers and academic and industrial partners in the consortium. This is an exciting opportunity for a researcher who wants to combine strong scientific contributions with real-world relevance in a rapidly evolving area of AI.

This is an exciting opportunity for a researcher who wants to combine strong scientific contributions with real-world relevance in a rapidly evolving area of AI.
In this role, you will investigate research questions related to agentic conversational systems, including benchmarking LLM-based conversational agents, studying multi-agent collaboration and coordination, designing metrics for long-horizon reasoning and planning, and studying tool-augmented conversational systems.
Given the 12-month duration of the position, your focus will be on delivering high-impact research outputs and helping establish reusable research infrastructure for the consortium. You will have the opportunity to develop new ideas, work across disciplines, and contribute to both methodological advances and practical applications in real-world settings.
Tasks and responsibilities
You are excited by recent developments in agentic AI and want to help shape this emerging area through strong scientific research. You see careful evaluation not as a side activity, but as a way to push the field forward and generate insights that matter. You enjoy working with real-world data and settings, and you appreciate both the richness and the messiness that come with them. You like turning complex, dynamic behaviour into research questions, experimental setups, and findings that others can build on. You work well independently, but you also value collaboration with colleagues and external partners.
Your experience and profile
We offer a temporary employment contract for 38 hours per week for a period of 12 months. The preferred starting date is as soon as possible.
The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 3,546 to € 5,538 (scale 10). This does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile Researcher 4 is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.

The Faculty of Science has a student body of around 8,000, as well as 1,800 members of staff working in education, research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works, be it elementary particles, the birth of the universe or the functioning of the brain.
The Informatics Institute (IvI) at the University of Amsterdam is one of Europe’s leading research institutes in computer science and AI. Its mission is to conduct curiosity-driven and use-inspired fundamental research.
You will be embedded in the Information Retrieval Lab (IRLab), one of the research groups within IvI. IRLab works on search and information access from a modern artificial intelligence perspective, combining machine intelligence with human intelligence to help people locate and act on the information they need. The lab offers an active and collaborative research environment with expertise in information retrieval, natural language processing, large language models, conversational AI, recommender systems, human-AI interaction, and evaluation. This makes IRLab a strong home base for research on agentic conversational systems and their study in realistic settings.
