San Diego Senior Optical Sensing Engineer

ASML•San Diego, CA

10h•$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 meet the needs of product teams and internal Research stakeholders. The team enables standalone EUV source qualification in San Diego by developing and owning internal EUV source metrology tools. The Senior Optical Sensing Engineer develops precision optical and electro-optical metrology systems used to measure, characterize, and support control of light production in extreme ultraviolet (EUV) sources for next-generation photolithography equipment. The systems 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 while supporting product development, Research, manufacturing, system integration, and internal customer needs.
