Overview
Natural language processing expert (m / f / d) (IT) - BS
Description :
The project aims to develop a machine learning system for the automated classification of assay protocol documents. The system will create a model or agent, track and improve its performance on challenging, imbalanced classes, and ensure it is robust and ready for integration into a production environment. The outcome will help scientists focus more on research, accelerate data access for project teams, and improve overall data quality.
The ideal candidate is an expert AI / NLP consultant with hands-on experience fine-tuning Transformer models and strong proficiency in PyTorch. They should have demonstrable experience with multi-task and multi-label classification, expertise in handling severe class imbalance in text data, and proficiency in deploying ML models as REST APIs. Strong software engineering fundamentals are also essential.
