Role Summary
We are hiring a hands-on Senior Data Scientist / AI Engineer to design and productionize AI capabilities for automated understanding and validation of complex 2 D engineering drawings. The role combines Computer Vision, OCR/Document AI, multimodal LLMs, RAG/Graph-RAG, Knowledge Graphs and deterministic engineering rules.
Key Responsibilities
Build AI pipelines to extract title blocks, notes, dimensions, tolerances, GD& T, datums, callouts, tables, references and drawing views from PDF/DWG/DXF-derived engineering content. Develop Computer Vision models for region detection, layout understanding, object detection, segmentation, symbol recognition, view classification and annotation localization. Design OCR/document-processing pipelines for dense technical drawings using tools such as Paddle OCR, Docling, Open CV, YOLO, Vision Transformers or equivalent frameworks. Build multimodal/LLM workflows for engineering interpretation, structured extraction, contextual reasoning and JSON-based outputs with solid guardrails.



Develop RAG and Graph-RAG solutions over engineering standards, specifications, component rules and business-unit guidelines using vector search and Knowledge Graphs such as Neo4j. Implement hybrid validation combining deterministic rule engines, symbolic checks and LLM reasoning; ensure exact geometric/tolerance checks are not delegated solely to LLMs. Create explainable review findings including violated rule, source/citation, confidence, rationale and recommended corrective action. Design Human-in-the-Loop feedback mechanisms to capture accept/reject/edit/override decisions and improve models, prompts, retrieval and rules. Model Evaluation & Productionization
Define accuracy benchmarks and golden datasets; track precision, recall, F1, Io U, OCR CER/WER, extraction accuracy, retrieval quality, validation accuracy and hallucination rate. Perform failure analysis, prompt/model benchmarking, regression testing and continuous accuracy improvement
