SD-26103 AI ENGINEER, RAG & LLM SYSTEMS FOR FINANCIAL COMPLIANCEFixed term contract | Belval | 24 MonthsAre you passionate about research? So are we! Come and join usThe Luxembourg Institute of Science and Technology (LIST) is a leading Research and Technology Organisation (RTO) that drives innovation for the economy and society in Luxembourg and beyond. With cutting-edge expertise in Natural, Built, Industrial environments, Space, AI, Security and defence technologies. LIST bridges scientific excellence and applied research to design solutions that address real-world challenges and create positive impact.Do you want to know more about LIST? Check our website: <a href="https://www.list.lu" target="_blank" rel="nofollow">https://www.list.lu</a>/How will you contribute?You'll be working on a production-grade Retrieval-Augmented Generation (RAG) system purpose-built for second-level controls on NAV computation in investment funds. The system must retrieve relevant regulatory methodology, replicate calculation steps, detect discrepancies against fund accounting outputs, and produce control reports that are traceable, auditable, and defensible under regulatory scrutiny. You will contribute to a system where precision, explainability, and reliability are non-negotiable.Code Development (60%):· Build retrieval pipelines optimised for structured regulatory methodology documents (CSSF circulars, ESMA guidelines, fund prospectuses), with adaptive weighting to surface the specific calculation rules relevant to each control query· Implement numerical validation pipelines that compare LLM-derived NAV calculation outputs against fund administrator figures, applying configurable tolerance bands and discrepancy flagging logic· Implement chunking strategies optimised for fund accounting reports and regulatory circulars, preserving the structure of calculation tables, formula references, and numbered regulatory provisions.· Build evaluation frameworks measuring control accuracy (error detection rate, false positive/negative rates on flagged discrepancies) and the quality of generated audit reports· Optimise vector database indexing for regulatory document corpora with high update frequency, ensuring fast retrieval as new CSSF/ESMA guidance is publishedResearch & experimentation (25%):· Benchmark embedding models against the current Nomic Embed Text baseline, with a focus on sensitivity to numerical and regulatory language in fund accounting contexts· Explore cross-lingual retrieval for EU regulatory documents published across multiple languages, with emphasis on French and German variants of CSSF and ESMA guidance· Research agent-based simulation of NAV calculation steps, investigating how LLMs can reason reliably over arithmetic-sensitive regulatory workflows and signal confidence levels· Experiment with multi-agent orchestration for second-level control workflows, where agents decompose a NAV control task into parallel verification sub-tasks across pricing, accruals, and corporate actions.System integration (15%):· Integrate LLM backends optimised for structured reasoning and develop prompt engineering patterns that enforce step-by-step calculation verification and explainable output· Implement comprehensive logging, structured audit trail generation, and monitoring dashboards that allow compliance officers to review and challenge control decisionsIs Your profile described below?
