Job summary

Keysight Technologies Inc. is seeking an Applied Data Scientist in California to design large-scale data architectures and robust pipelines that integrate simulation and measurement data for AI/ML model development.

You will partner across teams, build data lakes, and leverage tree-based ML, Bayesian optimization, and signal processing to drive R&D and product insights.

Qualifications

• Master’s or PhD in Data Science, Computer Science, Electrical Engineering, Statistics, or related field.
• 1+ years’ experience as a Data Scientist / Applied Data Scientist.
• Proven ability to build and maintain scalable data infrastructures (data lakes, schemas, pipelines).
• Strong programming skills in Python (pandas, numpy, scikit-learn), SQL, and optionally C++.
• Proficiency with Snowflake, Databricks, or similar big-data environments.
• Hands-on expertise in tree-based ML techniques and statistical modeling.
• Familiarity with Bayesian Optimization and feature engineering for time-series or signal data.
• Ability to move fluidly between data exploration, engineering, and modeling tasks.

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 (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.
