NLP Engineer _ Machine Learning Engineer|5+ years · Remote

We are looking for a hands-on NLP/ML engineer to lead the development of an intelligent document understanding pipeline for extracting structured data from complex, unstructured RFQ documents (40100+ pages, in German and English).

Responsibilities

• Design and implement document hierarchy and section segmentation pipelines using layout-aware models (e.g., DocLayout-YOLO, LayoutLM, Donut).
• Build multilingual entity recognition and relation extraction systems across both English and German texts.
• Use tools like NLTK, transformers, and spaCy to develop custom tokenization, parsing, and information extraction logic.
• Construct and maintain knowledge graphs representing semantic relationships between extracted elements using graph data structures and graph databases (e.g. Neo4j). Integrate outputs into structured LLM-friendly formats (e.g., JSON, Markdown) for downstream extraction of building material elements.
• Collaborate with product and domain experts to align on information schema, ontology, and validation methods.

What Were Looking For

• Strong experience in NLP, document understanding, and information extraction from unstructured/multilingual documents.
• Proficiency in Python, with experience using libraries such as transformers, spaCy, and NLTK. Hands-on experience with layout-aware models like DocLayout-YOLO, LayoutLM, Donut, or similar.
• Familiarity with knowledge graphs and graph databases such as Neo4j, RDF.
