Senior Data Scientist | Generative AI

This is a remote positition in Brazil, you will apply state-of-the-art tools (OCR, vision-language models, document understanding frameworks) to interpret diverse input types. You will develop and refine strategies for using LLMs to extract, summarize, and transform unstructured content into structured formats. Clean, validate, and transform messy, unstructured data into well-defined schemas ready for training or analytics pipelines. You will define standards and build systems for cleaning, validating, and filtering data to ensure accuracy, reduce bias, and align with ethical/safety guidelines. Design feedback loops where experts validate or enrich data, improving LLM-based extraction reliability, architect cost-efficient, high-throughput data pipelines that are robust to noisy or incomplete sources.
