About Keysight AI Labs
Keysight accelerates innovation to connect and secure the world. Our solutions span wireless communications, semiconductors, aerospace & defense, automotive, and beyond. We combine measurement science, simulation, and advanced AI to help engineers design, simulate, and validate the world’s most advanced systems.
About the AI Team
You’ll join a cross-disciplinary R&D team pioneering data-driven innovation at Keysight.
We collaborate closely with domain experts in simulation, measurement, RF systems, and AI to transform scientific and engineering data into actionable insights.
Our environment bridges machine learning, data engineering, and experimental science, giving you access to unique high-fidelity datasets that drive next-generation design, modeling, and analytics capabilities.
About the Role
As a Senior Applied Data Scientist, you’ll operate at the intersection of data engineering, data science, and machine learning. You’ll design and implement large-scale data architectures, develop robust data pipelines, and build high-quality ML models that integrate simulation and measurement data from diverse domains.
Your work will directly influence Keysight’s advanced R&D initiatives — from algorithm development to AI-assisted engineering tools.
Responsibilities
Partner with internal engineering and data teams to identify key data sources, define feature requirements, and align data standards across organizations.
Design, implement, and maintain data lakes, databases, and ETL/ELT pipelines (Snowflake, Databricks, SQL, Python).
Integrate, clean, and align simulation, measurement, and operational data for scalable AI/ML model development.
Conduct exploratory data analysis, dimensionality reduction (e.g., PCA), clustering, and regression to extract insights.
Develop and validate ML models using tree-based methods (XGBoost, LightGBM, Random Forests) and Bayesian Optimization for tuning.
Apply signal processing and data augmentation techniques to improve data quality and coverage.
Document data lineage, feature definitions, and modeling rationale for reproducibility and transparency.
Communicate insights and recommendations to stakeholders, influencing data-driven decisions across R&D and product teams.
Qualifications
Required Qualifications
