ML Engineer - NLP & Document AI

Clair transforms unstructured documents into actionable, structured data – and our ML pipeline is at the heart of it.

As an ML Engineer focused on NLP and Document AI, you will design and improve the models that extract, classify, and structure information from complex real-world documents.

What you will do

• Develop and fine-tune NLP models for document understanding
• Build extraction pipelines for tables, entities, and relationships
• Improve OCR post-processing and layout analysis
• Design evaluation frameworks and quality metrics
• Collaborate with engineering to integrate models into production

What you will build

Named entity recognition and relation extraction systems

Table detection and structured data extraction from PDFs

Classification models for document types and content segments

What we are looking for

• Strong background in NLP, information extraction, or document AI
• Experience with transformer-based models (BERT, LayoutLM, etc.)
• Proficiency in Python and ML frameworks (PyTorch, Hugging Face)
• Understanding of production ML systems and deployment
• Bonus: Experience with OCR systems or financial/ESG documents
