Plasma and Laser Physics Engineer
About The Position
The EUV Source team in San Diego works in a fast-paced, innovative, and highly technical environment to develop next-generation products supporting the commercialization of Extreme Ultraviolet (EUV) lithography technology. As part of the EUV Source Performance team, the Plasma and Laser Physics Engineer validates and optimizes EUV source performance to ensure products meet or exceed customer requirements. The role contributes throughout the product development lifecycle, including technology development, system validation, performance improvement, and customer support. It combines advanced physics, data analysis, experimental design, and hands-on engineering to address complex technical challenges and improve system performance. The engineer develops system-level expertise in EUV light source performance, including laser generation and amplification, laser-plasma interactions, debris mitigation, and control systems. The position involves designing and conducting experiments, developing system and subsystem test plans, analyzing large datasets, troubleshooting performance issues, and using diagnostic equipment to characterize system performance. The engineer documents findings, collaborates with cross-functional teams, supports customer escalations and technical recovery, and provides training to factory and field engineering teams. The position is based on-site in San Diego, California, with a flexible workplace arrangement potentially available for up to two remote days per week for work conducive to remote work. Travel may be required to support customers.
