Werkstudent*in in Data Science und Natural Language Processing bei Fraunhofer, tätig in KI-gestütztem Wissensmanagement und innovativer KI-Lösungsentwicklung.
Responsibilities
Our "Innovation & Transformation" department works, among other things, on AI-supported knowledge management in research and industry projects.
The focus areas are Human-AI interaction and Smart Circular Economy.
In this context we develop automated systems for knowledge extraction, knowledge management and decision support that we provide to companies and public organizations.
You will work with the latest technologies in industry and research projects, especially in the areas of generative AI, machine learning and transformer models.
You will assist in developing innovative AI solutions using large language models (LLMs) such as GPT-5, BERT or Google Gemini.
You will convert unstructured, domain-specific data into vector databases and build application-oriented RAG systems (Retrieval-Augmented Generation).
You will use fine-tuning, prompt engineering and other techniques to maximize the accuracy and performance of LLMs.
You will support data integration, ETL processes as well as the modeling and structuring of knowledge.
You will develop web applications and interfaces for chatbot systems and knowledge management tools.
You will actively help interpret data and contribute ideas for new AI use cases.
Requirements
You are enrolled in Business Informatics, Computer Science, Software Engineering, Data Science, Artificial Intelligence or a comparable degree program (at least in the first semester of a Master’s program).
You have initial practical experience in machine learning, AI algorithms and natural language processing.
You have strong programming skills in Python, including libraries such as pandas, scikit-learn, numpy and transformers.
You have knowledge of RAG methods (text preprocessing, chunking, semantic search (FAISS), reranking, output tuning) and agentic AI frameworks (LangGraph, LangChain or similar).
You are familiar with developing web applications (Flask, Streamlit, REST APIs).
You enjoy working in a team and demonstrate a strong willingness to learn and commitment.
You are interested in a long-term collaboration (at least 6 months).
Benefits
