You will contribute throughout the product development lifecycle by participating in technology development, system validation, performance improvement initiatives, and customer support activities. This role combines advanced physics, data analysis, experimental design, and hands‑on engineering to solve complex technical challenges and enable world‑class system performance. Role and responsibilities As a Plasma and Laser Physics Engineer, you will: Develop system‑level expertise on EUV light source performance, including laser generation and amplification, laser‑plasma interactions, debris mitigation, and control systems. Apply theoretical models, scientific methods, and experimental techniques to analyze source performance across multiple technical disciplines. Design, execute, and document scientific experiments to validate and optimize prototype hardware and software performance. Collect, process, and analyze large datasets using MATLAB, Python, and automated diagnostic tools. Troubleshoot complex performance issues, perform root‑cause analysis, and recommend corrective actions and design improvements. Use advanced diagnostic equipment and analytical tools to characterize and validate system performance. Collaborate closely with system architects, design engineers, scientists, manufacturing teams, customer support engineers, and senior leadership. Support customer escalations through remote and on‑site troubleshooting, data analysis, and system recovery activities. Provide technical training and knowledge transfer to factory and field engineering teams. Travel as needed to support customer‑site troubleshooting and performance recovery efforts. Ensure safe operation of equipment and adherence to ASML safety procedures. Education and experience To help us solve some of the semiconductor industry's most challenging technical problems, you'll need a strong background in plasma physics, optics, and complex system development. Bachelor's degree in Plasma Physics, Engineering Physics, Applied Physics, or a related field. Master's or PhD preferred. Experience designing and executing scientific experiments for product development and validation. Proficiency with MATLAB, Python, or similar data analysis and modeling tools Experience with semiconductor equipment development is preferred. Hands‑on experience operating optical, electrical, or plasma‑related laboratory instrumentation is a plus. Skills Working at the forefront of semiconductor technology means solving complex challenges alongside a diverse team of scientists and engineers. Excellent analytical, troubleshooting, and root‑cause analysis capabilities. Strong laboratory and experimental skills, including operation of test and analytical equipment. Strong interpersonal and relationship‑building skills across cross‑functional teams. Self‑directed with the ability to execute technical tasks with minimal supervision. Customer‑focused mindset with the ability to support high‑priority field escalations and technical recovery efforts. This position is located on‑site in San Diego, CA . A flexible workplace arrangement may be available to employees working in roles conducive to remote work (up to two days a week). Must be willing to work in a clean room environment, wearing coveralls, hoods, booties, safety glasses and gloves for entire duration of shift.
