ph3About us: /h3 pTransPerfect, a recognized leader in translation software with a vibrant start‑up spirit, is seeking a creative and passionate Backend Developer to join our innovative Artificial Intelligence (AI) team. As part of this division, you will have the opportunity to shape the future of AI in a general organization. From its beginnings over 10 years ago and the creation of its first machine translation models, the AI team has become a core driver of the company's innovation in machine translation, generative AI, natural language processing, and automation. /p h3About the Role: /h3 pAs a Backend Developer, you will help us solve the “last mile” of document processing: converting complex, unstructured PDFs into perfectly formatted, editable .docx files. The goal is not just to extract text, but to recreate the bvisual and structural intent /b of the original document—including nested tables, multi‑column layouts, font hierarchies, and styling. You will lead the research and implementation of our document conversion pipeline. This is a hybrid role requiring you to be both a strategic decision‑maker (staying on top of the existing tools) and a hands‑on developer (combining engineering and AI skills). /p ul liComparative Analysis: Perform a deep‑dive evaluation of commercial (ABBYY, Adobe, AWS Textract) vs. open‑source/AI‑native (Mistral OCR, Docling, Nougat, LlamaParse) solutions. /li liBenchmarking:



Establish metrics for “format fidelity” to objectively measure how well a tool recreates headers, footers, tables, and styles. /li liPipeline Development: Build a Python‑based workflow that integrates OCR engines with document generation libraries (like python-docx or Pandoc). /li liAI Implementation: Explore and fine‑tune Vision‑Language Models (VLMs) or LayoutLM‑style architectures to improve structural recognition. /li liOptimization: Solve specific edge cases such as rotated text, low‑resolution scans, and complex mathematical notation. /li /ul h3Technical Requirements /h3 ul liPython Mastery: Expert‑level Python skills with experience in OpenCV, PyMuPDF, and python-docx. /li liOCR/Document AI: Deep familiarity with Tesseract, PaddleOCR, and modern Transformer‑based document models (LayoutLMv3, Donut, or Nougat). /li liFormat Expertise: A “pixel‑perfect” mindset—understanding the nuances of XML‑based document formats (OOXML). /li liLLM Integration: Experience using GPT or Claude models for layout correction and semantic cleanup. /li liArchitectural Vision: Ability to decide when to use an “off‑the‑shelf” API versus when to build a custom PyTorch/TensorFlow pipeline. /li /ul h3Nice to Have /h3 ul liExperience with Pandoc AST (Abstract Syntax Trees) for format conversion. /li liBackground in DTP, Typography or Graphic Design. /li liContributions to open‑source OCR or PDF manipulation projects. /li /ul /p #J-18808-Ljbffr
