About this role

Chemican builds an AI platform for managing chemical-safety information (SDS — Safety Data Sheets), targeting the risk of pollution, health harm, and chemical accidents from mismanaged chemicals. As an AI Engineer you lead development and improvement of AI features with the CTO. Work includes: building systems that extract and structure information from SDS PDFs (high-accuracy OCR and layout parsing across English, Japanese, Chinese, and Spanish; normalization to each country's SDS format and regulations); developing a chemical-industry-specialized AI agent integrating diverse data sources (chemical DBs, regulatory DBs, protective-equipment catalogs) using tools such as LangChain; and building a confidence-scoring system that quantifies the reliability of inference results. Experience scanning/structuring other PDF documents such as invoices or contracts transfers well. Full-time; Tokyo.
