workflows.\n\nBuild, iterate on, and monitor applied ML models to proactively identify data or concept drift.\n\nEnrich and enhance datasets with product-ready calculated fields and derived metrics.\n\nAssist in building automated or ad-hoc QA validation processes to validate model output accuracy, reliability, and consistency.\n\nRequirements\n\n4+ years of previous experience as a Data Scientist, Data Analyst, or Data Engineer, with a strong background in data modeling, ML, and NLP.\n\nExcellent programming skills in Python, proficiency in SQL, and hands-on experience with
