Senior Data Scientist (NLP + GenAI)

Job Description

Are you passionate about cutting-edge AI and language models? Do you want to help shape the future of how people interact with Danske Bank? We’re looking for a Senior Data Scientist with a specialization in Natural Language Processing (NLP) and Generative AI (GenAI) to join our fast-growing AI team.

Who Are We

The Commercial Data Science CoE is a diverse team of Data Scientists, ML Engineers and MLOps Engineers with various educational and cultural backgrounds. We are responsible for applying AI in Danske Bank’s customer facing solutions, ranging anywhere from ML models used for personalisation and marketing optimisation to chatbots and advisor assistants.

We pride ourselves on being at the forefront of the latest technology and research identifying use cases where AI can be applied to create value for customer and the bank.

What You’ll Do

As a Senior Data Scientist, you’ll lead the development and deployment of language-driven solutions, including GenAI assistants, chatbots, RAG (Retrieval-Augmented Generation) systems, and enterprise NLP models. Your main responsibilities will be:

• Design, develop, and optimize advanced NLP/GenAI solutions using large language models (LLMs)
• Build and fine-tune models for text classification, entity recognition, summarization, Q&A, and conversational agents
• Collaborate with ML engineers, data engineers, and product teams to integrate models into production environments
• Drive experimentation, A/B testing, and model evaluation strategies
• Stay current with the latest research and industry trends in LLMs, transformers, and prompt engineering
• Mentor junior team members and contribute to best practices in model development and MLOps
  
  

What We’re Looking For

• 5+ years of experience in data science or machine learning
• Strong proficiency in NLP: transformers, tokenization, embeddings, etc.
• Experience with GenAI frameworks (e.g., LangChain, LlamaIndex, OpenAI APIs, Hugging Face, RAG architectures)
• Proficient in Python and ML libraries (e.g., PyTorch, TensorFlow, scikit-learn)
• Experience deploying models in production (e.g., Docker, Kubernetes, Azure/AWS/GCP)
• Strong understanding of evaluation metrics for NLP tasks (e.g., BLEU, ROUGE, F1, exact match)
• Excellent problem-solving skills and communication abilities
  
  

Nice to Have

• Experience with prompt engineering and instruction-tuned models
• Familiarity with vector databases (e.g., Pinecone, FAISS, Weaviate)
• Knowledge of responsible AI principles and model risk management
• Previous experience in a domain like finance, healthcare, or customer service chatbots
  
  

Why Join Us?

• Work on cutting-edge GenAI projects with real-world impact
• Join a collaborative, cross-functional team with room for autonomy
• Flexible working environment
• Working in our new HQ with great facilities
