About Keysight AI Labs Keysight’s AI Labs is a integral 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 6G 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 As a Senior Applied Machine Learning Engineer, you will design, implement, and deploy state‑of‑the‑art ML architectures that merge physics insights, numerical optimization, and modern AI techniques. You’ll contribute to building scalable and explainable ML systems, from geometry‑aware GNNs and Transformers to reinforcement learning and generative models,



that drive design automation, anomaly detection, and optimization in Keysight’s next‑generation platforms.

Responsibilities

Partner with Keysight experts in RF, EM, circuit, and measurement domains to translate physical constraints and design workflows into ML‑ready formulations.

Design and implement advanced ML architectures:

Graph Neural Networks (GNNs) for geometry/topology‑aware modeling

Transformers for sequential and multimodal data

Vision Models (CNNs, ViTs) for field‑ or spectrogram‑based detection

Generative Models (GANs, Diffusion) for data augmentation and design candidate generation

Apply advanced optimization and control methods:

Bayesian, gradient‑based, and gradient‑free optimization

Reinforcement Learning (PPO, DDPG, SAC) for continuous tuning and control tasks

Develop scalable training and inference pipelines (multi‑GPU, HPC, AWS) ensuring efficiency and reliability.

Write production‑ready code in Python, C++, and CUDA, integrating with CI/CD pipelines and performance profiling tools.

Benchmark ML and RL models against physics simulators and measurement datasets for robustness and reproducibility.

Collaborate with product teams to embed AI/ML‑based optimization and generative modules into Keysight software.

Stay current with the latest ML, RL,



and generative AI research; evaluate and prototype promising new techniques.
