About the Role
We are seeking an experienced Machine Learning Engineer (GenAI / LLM) to lead the development of intelligent document processing (IDP) systems specializing in historical and archival records. In this role, you will design end-to-end computer vision and LLM/VLM pipelines to restore degraded scans, transcribe complex handwriting (HTR), and extract structured, schema-validated data from records such as census ledgers, birth, marriage, and death certificates. You will leverage modern OCR/HTR models, fine-tune vision-language architectures, and deploy scalable cloud-based inference pipelines to turn complex, unstructured historical archives into reliable, searchable databases.

Key Responsibilities
• Archival ML Pipelines: Architect, train, and deploy robust, multi-stage pipelines tailored for historical document processing—spanning ingestion, preprocessing, binarization, de-skewing, line/word segmentation, transcription, and structured entity extraction.
• Handwritten Text Recognition (HTR) & Layout Analysis:



Design and fine-tune computer vision and deep learning models for layout analysis, table extraction, and handwriting transcription across diverse scripts, historical cursive styles, varied ink qualities, and tabular forms.
• Document Image Restoration: Apply advanced computer vision techniques (using OpenCV, PyTorch, etc.) to enhance low-contrast, bleed-through, degraded, or faded historical scans while strictly preserving resolution, archival integrity, and metadata.
• OCR/HTR Engine Integration: Benchmark, integrate, and customize managed document AI tools (AWS Textract, Google Cloud Document AI / Vision API) alongside open-source OCR/HTR frameworks (e.g., TrOCR, PaddleOCR, Kraken, Tesseract) to maximize character/word-level accuracy on non-standard typography and handwriting.
• LLM & Multimodal (VLM) Extraction: Implement open
- and closed-source LLMs/VLMs (e.g., Gemini, Claude, GPT-4o, LLaMA, Mistral, Qwen-VL) to transcribe, normalize, correct OCR/HTR errors, and extract schema-adherent fields (names, dates, relationships, locations, causes of death, occupations) from unstructured or semi-structured records.
• Entity Linking & Structured Output Generation: Develop reliable post-processing pipelines using Named Entity Recognition (NER), regex validation, and JSON/Pydantic schemas to output standardized, audit-ready data suitable for database ingestion and genealogical/client analytics.
• MLOps, Serving & Scaling: Build, monitor,



and scale distributed, multi-threaded batch and streaming inference pipelines using tools like MLflow, Docker, Ray, AWS SageMaker, or GCP Vertex AI to efficiently process massive collections of high-resolution image archives.
• Quality Assurance: Define CER/WER metrics, entity-level validation, schema validation pass rates) and human-in-the-loop (HITL) active learning workflows to track accuracy and refine model confidence. Required Qualifications
• Education &

Experience:
Bachelor’s or Master’s in Computer Science, Data Science, or related quantitative field, with 5+ years of production ML/CV experience.
• Computer Vision & HTR: Hands-on experience with layout analysis, object detection, and deep-learning-based handwriting recognition (TrOCR, ViT, CRNN).
• Applied LLM/VLM

Skills:
Direct experience fine-tuning, prompting, and serving LLMs/VLMs for structured data extraction and reasoning over complex documents.
• Core Technical Stack: Advanced Python proficiency using PyTorch, OpenCV, Hugging Face Transformers, and distributed data processing libraries.
• Cloud & MLOps: Practical experience with AWS or GCP ML stacks (SageMaker, Vertex AI), containerization (Docker), model serving, and lifecycle tracking. Preferred Skills
• Practical experience with historical census, vital records, or dense tabular document parsing.
• Hands-on knowledge of Multimodal RAG, vector databases, and spatial bounding-box indexing.
• Experience generating synthetic handwriting datasets or mentoring junior ML engineers. Work
