About the project

• About our Team
• As one of the largest AI teams in Europe, we work with the analysis of text, sound, image, speech, Big Data, NLP, and more. We base our work on the latest methods of machine learning (including deep neural networks), extensive data resources, and appropriate computing resources. We conduct research on the latest AI technologies and working on Samsung's Big Data to provide our customers with the highest level of experience.
• About the role
• We are looking for a Senior AI Engineer with proven experience in training large language models (LLMs), encoder-based architectures and general-purpose machine learning algorithms. You will leverage and develop state-of-the-art AI technologies, especially in the text domain. Your responsibilities will include creating and managing high-quality datasets—both supervised, collaborating closely with labeling teams, and self-supervised approaches—while selecting and applying appropriate evaluation metrics. Your expertise will be applied to develop advanced systems at Samsung, working with internal data to generate sophisticated analyses of large-scale data sets. The core of your work will focus on pushing the boundaries of data-driven insights and building next-generation smart features that empower intelligent user experiences. Join us to contribute to cutting-edge AI solutions that redefine how millions interact with technology worldwide.
