patsnap - Senior Machine Learning Engineer (AI Agent)

• Responsible for analysing and understanding of the massive structured and unstructured data by NLP tasks, such as data processing, NER, relationship extraction, NOR etc. • Own and improve our information-extraction pipeline, from model to production • Solve document-level extraction at scale — design how we handle long documents where entities, properties, and their relationships span across sections • Independently drive algorithm optimization, develop and fine-tune models to meet business requirements. • Build hybrid systems combining NER, rule-based methods, and LLMs, applying each where it genuinely wins • Define evaluation methodology / annotation strategy / quality metrics with domain experts • Process and extract from large-scale corpora reliably and efficiently
