Job description
Keysight AI Labs Keysight's AILabs is a global R&D group pioneering the integration of machine learning, generative AI into Keysight's test, measurement, and design solutions. Our mission is to transform how engineers design, simulate, and validate advanced systems-from 6 G and semiconductors to quantum and automotive-by embedding AI throughout our workflows. About the AI Team Join Keysight's central AI Hub in the heart of Barcelona. We are expanding our newly formed AI Team. As part of this growing team, you will join a vibrant, cross-functional environment that brings together experts in ML engineering, data science, physics-informed modeling, and software development. You'll work closely with domain experts across RF, EM, circuit design, and test & measurement to accelerate scientific innovation through AI. About the Role We are seeking a Senior Applied Data Scientist with strong data engineering capabilities. You will explore complex engineering data, architect scalable data infrastructure, and shape the data foundation powering AI model development across Keysight products. This role bridges research and production, from data discovery to robust ETL/ELT pipeline design and feature creation for ML models. Responsibilities Partner with internal experts to identify critical data sources and define ML-relevant features Architect and build scalable data lakes/databases for standardized and efficient cross-org data access Clean, align, normalize, and integrate data from simulations, measurements, and operational systems Develop and maintain reproducible ETL/ELT pipelines for structured and unstructured data using SQL, Python, Snowflake, and cloud-native workflows Perform EDA, feature engineering, regression, and dimensionality reduction to generate high-value insights Ensure data governance, lineage, metadata management, and compliance Support experiment design, hypothesis testing, and statistical modeling Work closely with ML engineers to accelerate model
