San Diego Senior Optical Sensing Engineer

ASML•San Diego, CA
•$143,063 - $209,825

About The Position

The Non-Product Metrology (NPM) group develops metrology capabilities that advance EUV source learning, support EUV power scaling, and serve product teams and internal Research stakeholders. In San Diego, the team develops and owns internal EUV source metrology tools for standalone source qualification. The Senior Optical Sensing Engineer develops precision optical and electro-optical metrology systems to measure, characterize, and support control of light production in EUV sources for next-generation photolithography equipment. The systems may combine optical sensing, detectors, cameras, lasers, electronics, signal processing, optomechanics, thermal mechanics, mechatronics, automation, controls, and software. The engineer owns one or more major metrology subsystems from requirements definition through design, procurement, assembly, integration, testing, verification, and release. The role provides technical leadership to cross-functional teams and suppliers, and supports product development, Research, manufacturing, system integration, and internal customer needs.
