Feature Engineer

We are seeking a Feature Engineer to design, develop, and optimize high-quality features for machine learning and artificial intelligence (AI) models. The ideal candidate will transform raw data into meaningful, predictive features that improve model performance, scalability, and reliability. This role requires expertise in data preprocessing, feature extraction, feature selection, statistical analysis, and collaboration with data scientists, machine learning engineers, and data engineers to build production-ready AI solutions.

• Analyze structured and unstructured data to identify meaningful features for machine learning models.
• Design and implement feature engineering pipelines for classification, regression, recommendation, forecasting, and NLP applications.
• Perform data cleaning, transformation, normalization, encoding, aggregation, and feature extraction.
• Develop and maintain reusable feature stores and feature management workflows.
• Engineer features from text, images, time-series, geospatial, sensor, and transactional datasets as applicable.
• Evaluate feature importance using statistical methods and machine learning techniques.
• Collaborate with data scientists to improve model accuracy through feature optimization.
• Automate feature generation, validation, and monitoring in production environments.
• Ensure consistency, versioning, and governance of engineered features across ML workflows.
• Optimize feature pipelines for scalability, performance, and real-time inference.
• Document feature engineering methodologies, assumptions, and best practices.
• Stay current with advancements in automated feature engineering, feature stores, and AI technologies.

• Bachelor's or Master's degree in Computer Science, Data Science, Artificial Intelligence, Statistics, Mathematics, Engineering, or a related field.
• 2–6+ years of experience in machine learning, data engineering, feature engineering, or data science.
