LLM / RAG Engineer (Contractor, 6-12 months)
vor 2 Wochen
About the Foundation The Foundation for Value Creation develops data-driven frameworks that measure how societies and firms create sustainable value. Following the success of the Elite Quality Index (EQx), a macro-level index, the Foundation is now building the Value Creation Rating (VCr), a micro-level framework assessing value creation and extraction across thousands of firms. To make these datasets accessible and interactive, we are developing the EQx and VCr Chatbots: AI-driven analytical assistants that help policymakers, researchers, and investors explore data, compare results, and interpret value creation dynamics across institutions and firms. Your Role This is not a routine IC position: it's a hands-on role at the intersection of research, technology, and product impact. You will collaborate with our technical advisors, including the CEO of explaino, to design and implement the core AI systems behind the EQx and VCr Chatbots. Tasks Design and implement the end-to-end AI pipeline for retrieval-augmented generation (RAG) and structured query answering. Apply state-of-the-art NLP and LLM methods, including embedding generation, retrieval optimization, and advanced prompting strategies. Integrate Azure OpenAI models with document and metric databases (Weaviate, PostgreSQL/pgvector) through FastAPI endpoints. Evaluate and improve model quality, using frameworks such as PromptFlow, RAGAS, or DeepEval for hallucination tracking and citation accuracy. Collaborate with data and frontend developers to surface firm-level insights through explainable, transparent outputs. Contribute to architecture discussions around scaling, caching, and fine-tuning evaluation metrics. Requirements Qualifications: 3+ years of experience as an AI Engineer, Data Scientist, or Applied Researcher. Solid Python skills and experience in one or more of: Hugging Face Transformers, LangChain, LlamaIndex, or Weaviate. Familiarity with Azure cloud architectural services and FastAPI (Key Vault, Blob Storage, AI Search, or ML Studio). "Working knowledge of CI/CD and containerized deployment (e.g., Docker, GitHub Actions, or Azure DevOps)." Working knowledge of vector databases and embedding pipelines (Weaviate, pgvector, Pinecone, Milvus, etc.). Ability to evaluate and improve model performance with classic NLP and modern transformer-based techniques. Experience with at least one of: PyTorch, Optuna, Peft & LoRA, Scikit-learn, Numpy, Pandas, or NLTK. Understanding of data analytics and reproducible evaluation practices. Comfortable using AI-assisted coding tools (e.g., GitHub Copilot, Claude, or ChatGPT), responsibly to accelerate delivery. Nice to have: Academic or research background (e.g., in NLP, information retrieval, or data science). Familiarity with visualization libraries, data lineage systems, or basic React development. Prior experience deploying AI applications in Azure or other regulated cloud environments. Benefits Opportunity to build real-world AI tools grounded in academic research and social impact. Work closely with experienced engineers and researchers from the University of St. Gallen ecosystem. Authorship credit on public research and technical outputs. Flexible, mission-driven environment emphasizing open collaboration and responsible AI practices. Competitive contractor compensation (region-based, CHF 4.5–9k/month). You'll join a collaborative, research-driven team shaping how data and AI inform value creation across economies and firms.
