As an 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.

• 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.

• 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.

Desired Qualifications

• Experience in data architecture design, schema governance, or cross-team data standards.

• Knowledge of MLOps principles for productionizing models and maintaining pipelines.

• Experience with metadata management and feature store design.

• Prior exposure to environments combining simulation and real-world measurement data.
