## Description

Introduction to the job Help solve some of the most complex physics and engineering challenges in the semiconductor industry. As a Principal Plasma and Laser Physics Engineer on the EUV Source Performance team in San Diego, you’ll help ensure that ASML’s EUV light sources meet or exceed customer performance requirements. You’ll develop deep system-level expertise and work at the intersection of laser physics, plasma physics, optics, controls, data analysis, and system engineering. You’ll contribute throughout the product development lifecycle, from early technology development and system definition through integration, validation, field introduction, and sustaining support. Your work will help improve the performance, reliability, and availability of EUV source technology used by customers around the world. Role and responsibilities You’ll be part of the EUV Source Performance team, working across disciplines to characterize system performance, validate new technologies, troubleshoot complex issues, and drive continuous improvement of EUV source products. As a Principal Plasma and Laser Physics Engineer, you’ll: Develop system-level expertise of the EUV light source and serve as a technical expert in areas such as laser light generation and amplification, laser-plasma interaction, debris mitigation, optics, and control systems. Apply physics-based models, analytical methods, and experimental techniques to characterize and improve EUV source performance across multiple technical disciplines. Design and execute experiments to validate hardware and software performance, investigate technical issues, and verify system and subsystem requirements. Collect, process, and analyze large data sets using tools such as MATLAB and Python to assess system performance, identify technical risks, and determine root causes. Develop and review system and subsystem test plans, ensuring traceability between functional requirements, test methods, and performance results. Lead structured troubleshooting and root-cause analysis of complex system-level issues and recommend improvements to performance, reliability, serviceability, and system design. Collaborate with systems engineering, development engineering, scientists, manufacturing, customer support, marketing, and other teams to establish technical direction and resolve cross-functional challenges. Support customer-site escalations through remote and on-site troubleshooting, data analysis, recovery planning, and technical guidance while transferring knowledge to factory and field engineering teams. Document and communicate technical findings, test results, recommendations, and lessons learned while helping drive. technology improvements and future product development. Other duties as assigned. Education and experience To help us tackle the technical challenges we face, you’ll need a strong background in physics or engineering combined with experience solving complex technical problems. As a Principal Plasma and Laser Physics Engineer, you’ll need: Bachelor’s degree with at least 10 years of relevant experience, Master’s degree with at least 8 years of relevant experience, or PhD with at least 5 years of relevant experience in Plasma Physics, Engineering Physics, Applied Physics, or a related technical discipline. Strong knowledge and experience in one or more areas such as optics, lasers, laser-induced plasma, plasma physics, optical metrology, or control systems. Experience applying physics and engineering principles to complex system-level problems. Experience designing experiments, developing test plans, analyzing results, and performing root-cause analysis. Experience with complex system or subsystem integration, characterization, validation, and troubleshooting. Experience with semiconductor equipment development or other complex high-tech systems is a plus. Skills Working at the cutting edge of technology, you’ll regularly encounter technical challenges that require collaboration across
