About the Team

At Keysight, we build advanced software and AI systems that power engineering innovation across electronics, communications, automotive, energy, aerospace, and semiconductors.

This role sits within Keysight’s Applied AI & Autonomy initiative, a multidisciplinary R&D effort developing intelligent, agent-based systems that learn from real-world engineering data, simulations, and measurements. The team combines machine learning, data engineering, and scientific modeling to create adaptive, explainable AI for complex engineering workflows.

About the Role

As a Senior Machine Learning Engineer, you will design and develop machine-learning models and data systems that learn from engineering data and continuously improve through feedback from simulations and measurements.

This is a hands-on, applied ML role, focused on:

• Scientific and engineering datasets

• Model generalization and robustness

• Explainability and trust in predictions

You will work closely with simulation engineers, measurement experts, and software developers to bring ML into real engineering decision-making.

• Design and train ML models that capture engineering and physics-driven behaviour
• Build and maintain data pipelines for structured, semi-structured, and experimental data
• Develop feedback loops where new data triggers model updates or retraining
• Implement explainable AI (XAI) techniques to make model decisions transparent and traceable
• Create diagnostics for model performance, drift, uncertainty, and anomalies
• Collaborate with domain experts to align ML models with real-world engineering use cases
• Continuously validate and refine models using real measurement and simulation data

Required Qualifications

• MSc or PhD or 5+ years of hands-on experience in machine learning, data science, or scientific computing

• Strong foundations in applied machine learning (model training, evaluation, generalization)

• Experience working with complex, real-world datasets (engineering, scientific, or industrial)

• Proficiency in Python and ML frameworks such as PyTorch

• Solid experience in data preprocessing, feature engineering, and pipeline automation

• Experience building interpretable or explainable ML models

• Comfortable collaborating in cross-functional, international teams

Desired Qualifications

• Experience with scientific computing, simulation-driven ML, or surrogate models

• Knowledge of physics-informed or hybrid ML approaches

• Familiarity with uncertainty estimation, sensitivity analysis, or confidence scoring

• Exposure to MLOps tools (e.g. MLflow, DVC) and experiment tracking

• Experience with high-performance or GPU-based training environments

• Some C++ exposure for performance-critical components
