About Keysight AI Labs

Join Keysight's central AI team in Barcelona , a newly formed hub driving innovation in machine learning. As part of this growing team, you’ll have the chance to shape our AI strategy and make an immediate impact. Our work spans supervised and unsupervised learning, generative models, multimodal systems, reinforcement learning, and large language models.

About the AI Team

We are expanding the Team and You’ll join a cross-disciplinary AI & Modeling team in the heart of Barcelona. The Team develops physics-informed, data-driven, and reinforcement learning systems that accelerate design, measurement, and optimization processes across domains such as RF, EM, circuits, and advanced instrumentation. The group collaborates closely with hardware engineers, domain scientists, and product software developers to bring AI models from research into production tools used globally.

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.
