Senior NLP/LLM/LLMOps Data Scientist

Build trustworthy AI for one of Europe's leading banks Large Language Models are transforming how organizations process information, support decisions, and serve customers. At ING, we're applying these technologies to one of the most demanding environments possible: banking. As part of our global Analytics Engineering organization, you'll help build conversational AI solutions, Retrieval-Augmented Generation (RAG) systems, and intelligent agent-assist capabilities that support customer-facing and operational teams across multiple countries. This is an opportunity to work on AI systems where success is measured not only by performance, but also by reliability, explainability, and trust. Why This Role Is Different Many NLP and LLM roles focus on recommendation systems, personalization, or content generation. At ING, you'll work on AI solutions operating in a regulated environment where accuracy, auditability, and responsible AI practices matter as much as model performance. You'll help develop solutions that support KYC processes, document understanding, conversational AI, and knowledge-intensive workflows that enable teams across multiple countries to make better and faster decisions. Role Summary As a Senior NLP / LLM / LLMOps Data Scientist , you will work at the intersection of Natural Language Processing, Generative AI, Information Retrieval, and Machine Learning Engineering. You will partner with ML Engineers, Customer Journey Experts, Product teams, and business stakeholders to design, build, and operationalize production-grade NLP and Generative AI solutions. Your responsibilities will span the full lifecycle of AI development—from experimentation and model development to deployment, monitoring, evaluation, and continuous improvement. As part of ING's global Analytics organization, you'll contribute to conversational AI and KYC capabilities supporting teams across multiple countries and business domains.

Team members typically come together in our Vadistanbul office for two days per week during three weeks of the month, while one week each month is fully remote. We also offer additional flexibility during August, allowing colleagues to work remotely throughout the month. As part of a globally distributed organization, you'll collaborate with colleagues across multiple ING locations while contributing to large-scale AI initiatives that create impact across the bank.
