Job Description

Are you looking to build a career in Artificial Intelligence, Machine Learning, Data Science, and large-scale data analytics? Nielsen is hiring for the position of AI/ML Data Scientist I in Bengaluru. Candidates with 0–3 years of work experience and a relevant degree can apply. This opportunity is particularly relevant for early-career data scientists who want to work on real-world machine learning, data engineering, statistical methodology, cloud computing, and audience measurement problems. The role combines data science, software development, data engineering, artificial intelligence, machine learning, and statistical analysis. Candidates will work on measurement and planning solutions used by publishers, advertisers, and agencies while helping productionize data pipelines and machine learning models. The AI/ML Data Scientist I position is designed for candidates who want to work across the boundaries of data science, software engineering, and data engineering, taking data science projects through the complete lifecycle. This includes exploring and cleaning data, identifying useful variables, applying statistical and machine learning techniques, building data pipelines, deploying models, validating methodologies, monitoring production systems, and documenting the resulting methodologies and code. Candidates will also work on audience measurement problems such as trend analysis, missing-data imputation, sampling and representation, bias reduction, indirect estimation, and data integration.
