Data Scientist (m⁠/⁠f⁠/⁠d)

Your work duties and responsibilities include:

• Innovative AI solutions – You design and implement solutions based on machine learning, deep learning, and large language models (LLMs), working with models such as Claude and GPT.
• Natural language processing (NLP) – You develop and optimise retrieval-augmented generation (RAG) systems, working with vector and metadata search, reranking, chunking, and prompt engineering to improve model accuracy.
• Multimodal models – You work with models combining text and image data and apply them within professional insurance software systems.
• Fine-tuning and optimisation – You apply advanced techniques for fine-tuning foundation models, tune hyperparameters, and evaluate AI solution performance.
• ML in insurance – You apply mathematical, statistical, and actuarial methods to model financial and insurance processes.
• Cloud – You develop infrastructure (IaC: AWS CDK) and integrations (AWS SDK), and deploy and operate AI applications in production (scaling, monitoring, incident management).
• Research and collaboration – You participate in research projects and collaborate with universities and research institutions to bring new approaches into practice.
• Teamwork and knowledge sharing – You work as part of a team of experts, share know-how, discuss ideas, and collectively push the boundaries of what AI can do.
