Overview

Keysight is at the forefront of technology innovation, delivering breakthroughs and trusted insights in electronic design, simulation, prototyping, test, manufacturing, and optimization. Our ~16,800 employees create world-class solutions in communications, 5G, automotive, energy, quantum, aerospace, defense, and semiconductor markets for customers in over 100 countries. Learn more about what we do.

Our award-winning culture embraces a bold vision of where technology can take us and a passion for tackling challenging problems with industry-first solutions. We believe that when people feel a sense of belonging, they can be more creative, innovative, and thrive at all points in their careers.

As a member of Keysight’s AI-focused Solutions Engineering team, the Solution Engineer works closely with our account managers and plays a key role in identifying customers’ test challenges early and defining the optimal measurement and validation approach. The role provides technical pre- and post-sales support, customer presentations, demonstrations at marketing events, and customer training, with a particular focus on the high-speed digital and photonic technologies that enable and accelerate AI infrastructure.

Typical customer requirements include state-of-the-art signal analysis, compliance, characterization, and validation solutions for electronic and photonic components used in AI compute, storage, and data-center networking. Application areas include high-speed interconnects and SerDes, PCIe and CXL, Ethernet and optical links, memory interfaces, and other technologies that increase the performance, bandwidth, power efficiency, and scalability of AI systems.

Customers include leading semiconductor, compute, data-center, wireless, and communications companies, as well as universities, medium-sized companies, and start-ups developing technologies for next-generation AI infrastructure.

Responsibilities

The position requires international collaboration with colleagues worldwide, our factories, and the broader Keysight AI ecosystem. You will serve as a technical interface between customers and Keysight product development, translating emerging AI infrastructure requirements into effective test strategies and helping shape solutions for rapidly evolving standards and architectures.

• Typical customer requirements are solutions for a wide range of signal analysis and electronic component test applications always in front of future state-of-the-a rt technologies.
• The customers are major accounts in the Wireless and Communication Industry as well as Universities and Geographic mid-size and start-up companies. The position is located in the Keysight Technologies office Madrid or Barcelona in Spain.
• The position requires international cooperation with colleagues world-wide and our factories. You are the technical interface between the customers and Keysight product development.
• A comprehensive technical training program, complemented by the development of the specialist skills required in the sales and service environment, will enable you to start your new position effectively.
• Customer visits require frequent travel (> 50% of work time).

Qualifications

The position requires a University Degree in electrical / communications engineering, physics, computer engineering, or an equivalent course of study and a minimum of 3 years’ professional experience in digital and/or photonic test and measurement applications. Experience with technologies used in AI compute, data-center, semiconductor, or high-performance networking environments is an advantage.

The following job-related skills are required:

• Comprehensive knowledge of Digital and Photonics test fundamentals in theory and practical measurement applications
• Practical experience using Oscilloscopes, Bit Error Rate Testers, Protocol Analyzers, optical instruments and other state-of-the art measurement instrumentation
• Strong personal interest in the AI sector and curiosity about the technologies accelerating AI innovation, including GPUs and AI accelerators, high-speed interconnects, data-center networking, memory technologies, and optical connectivity
• Knowledge of High-Speed Digital PHY standards and interfaces relevant to AI infrastructure, such as PCIe, CXL, DDR, high-speed Ethernet, and OIF CEI, including an understanding of SerDes validation and signal-integrity challenges
• Ability to connect high-speed digital and photonic measurement challenges with AI system performance, scalability, reliability, and energy efficiency, and to communicate this value clearly to technical and business stakeholders
• Practical experience in the development and setup of test systems
• Programming skills applied in a T&M environment such as Python, Matlab, and C/C++/C#
