You will review document layouts, revise/add/classify bounding boxes, validate table structures, check reading order, and ensure Korean text is accurately captured and correctly interpreted.

You will also provide clear feedback to annotators on Korean-language correctness, OCR transcription issues, layout errors, entity classification mistakes, and guideline adherence. This role requires strong Korean language expertise, excellent attention to detail, comfort with complex document annotation workflows, and the ability to consistently apply detailed QA guidelines across large volumes of work.

Your Korean QA expertise will directly support high-quality OCR and document understanding datasets by ensuring Korean-language documents are accurately structured, annotated, and ready for model training.
