Postdoctoral Researchers, Language Technology

Postdoctoral researchers Explainable & Trustworthy AI for Global Threat Analysis ( “Know-AI” ) AI for language teaching and language learning ( “DALAI-FIN” ) University of Helsinki – Department of Digital Humanities, Language Technology Position type: Full-time postdoctoral researchers Duration: initially 2 years (with possibility of extension) Start date: immediate Overview of Projects: The Know‑AI project investigates what language models know and when they know it. The mission is to develop explainable and trustworthy AI systems for detecting and analyzing global threats, including disinformation in online media. The successful candidate will contribute to cutting-edge research in large language models — their interpretability, robustness, and real‑world safety. The DALAI-FIN / Revita project focuses on supporting second-language teaching for adults, for example migrants in Finland (or elsewhere in Europe), who require linguistic skills for professional and social integration. Learners have different levels of preparation and different backgrounds. Research goals include the development of AI-based tools for personalized teaching, i.e., exactly suitable for the current level of competency of each individual learner. This implies detailed and accurate learner modeling, learning analytics and assessment of the learner's skills, on a continual basis. The projects cooperate with an international network of collaborators.

Position Description As a postdoctoral researcher in this project, you will:

• Conduct foundational and applied research on explainability and trust in language models.
• Develop methods to evaluate, interpret, and improve how LLMs detect and represent potential threats or risk scenarios.
• Collaborate closely with project research teams and external partners, including interdisciplinary groups.
• Implement algorithms and data analysis (e.g., using PyTorch, JAX, transformers).
• Publish papers at premier AI/ML/NLP venues and domain-related conferences.
• Present results at academic conferences and workshops.

Requirements You must have:

• A PhD degree (or imminent completion expected) in Natural Language Processing, Machine Learning, Computer Science, or related discipline.
• Experience with and strong interest in NLP, large-language models, explainability.
• Demonstrated programming skills in Python, ideally including frameworks, such as PyTorch and HuggingFace Transformers.
• Prior peer-reviewed publications (required for postdoctoral appointment).
• Excellent oral and written communication in English.

Salary & Benefits Starting salary: ~3 700–4 400 EUR/month before taxes, consistent with salary scales of the University of Helsinki. Comprehensive employee benefits including occupational health care, health insurance, sports facilities, and professional development support. In Finnish universities, the teaching and research staff (app. 65% of total staff) have a special system regarding the free time equivalent to holiday. They belong to the 1,612 annual working hour system, in which the annual amount of paid holiday is app. 5-6 weeks on average per year. The appointee is expected to reside in Finland while employed by the University of Helsinki. The university is an internationally renowned research university offering a wide range of staff benefits, including occupational health care and health insurance, flexible working hours, excellent campus sports facilities, and opportunities for professional development. International Staff Services support for relocation and settling in Finland.
