您将如何贡献和成长？

Focusing on the business needs of Air Liquide in the context of our customer-centric transformation, the researcher will be responsible to:

• Collaborate with business entities to define the problem and business requirements, translate them into functional design specifications, and develop solutions. Identify, evaluate and select industrial or academic partners as needed.

• Lead and participate in the design, development, and deployment of AI solutions based on Large Language Models (LLMs) to address key challenges in industrial, R&D, and healthcare domains.

• Lead the fine-tuning and optimization of open-source LLMs (e.g., Llama, Qwen, DeepSeek) for specific business scenarios (such as technical document comprehension, process parameter optimization, safety report analysis, and scientific knowledge mining).

• Expertly apply Retrieval-Augmented Generation (RAG) techniques, integrating internal knowledge bases (e.g., technical patents, engineering manuals, research reports) with external data to build high-accuracy intelligent Q&A, content generation, and knowledge management systems.

• Test and verify the performance of solutions with prototypes developed.

• Define and develop business tools based upon the prototype performance verification, ensure transfer of the tool to the operational entities and provide support for the industrial deployment.

• Train team members on the details of the implemented methodology, thus ensuring sustainability of the solution for Air Liquide.

• Support knowledge transfer within Air Liquide. Publish research in internal R&D reports, at conferences and potentially in peer-reviewed journals.

• Work with IT, internal, and external organizations to obtain, clean, visualize, and analyze data.

• Continuously track the latest advancements in NLP, LLM, and Generative AI (GenAI) (e.g., Agents, Multi-modality), evaluating and introducing new technologies to enhance team capabilities.
