The team enables comprehensive standalone EUV source qualification in San Diego by developing and owning internal EUV source metrology tools.\nThe Senior Electro-Optical Systems Engineer develops precision optical and electro-optical metrology systems used to measure, characterize, and support the control of light production in extreme ultraviolet (EUV) sources for next-generation photolithography equipment. These systems combine optical sensing, detectors, cameras, lasers, electronics, signal processing, optomechanics, thermal mechanics, mechatronics, automation, controls, and software.\nThis role owns one or more major metrology subsystems from requirements definition through design, procurement, assembly, integration, testing, verification, and release. The engineer provides technical leadership to cross-functional teams and suppliers while supporting product development, Research, manufacturing, system integration, and internal customer needs.\nRole and responsibilities\nTranslate equipment, system, and stakeholder needs into metrology requirements, subsystem specifications, interface definitions, performance budgets, and verification plans.\nLead the definition, development, and integration of optical and electro-optical metrology systems that enable EUV source learning, power scaling, stable operation, and improved system availability.\nDevelop sensing systems involving lasers, illumination and imaging optics, detectors, cameras, fibers, filters, coatings, optomechanical assemblies, and signal-processing hardware.\nDevelop specifications for light-emitting, light-delivery, and light-sensing modules in accordance with system-level and cross-functional requirements.\nPerform photon-budget, radiometric, and signal-to-noise ratio calculations that account for source output, optical transmission, detector response, background signal, electronic noise, and other system noise sources.\nConduct optical performance, tolerancing, stray-light, beam-propagation, alignment, calibration, and image- or signal-quality analyses.\nApply knowledge of optics, sensors, electronics, algorithms, software, and data analysis to improve metrology performance.\nOwn metrology subsystems through component selection, supplier engagement, procurement, assembly, alignment, integration, testing, qualification, and release.\nIntegrate optical hardware with low-voltage electronics, motors, analog sensors, precision mechanisms, controls, software, motion systems, and thermal-management hardware.\nDevelop laboratory test benches, diagnostic tools, fixtures, calibration methods, test procedures, acceptance criteria, and automated data-analysis tools.\nPlan and execute laboratory and cleanroom testing for design validation and verification.\nCorrelate analytical and numerical predictions with measured results and resolve performance gaps.\nLead integration and troubleshooting activities to verify that metrology systems function as designed within the EUV light source.\nLead root-cause investigations involving optical, electrical, mechanical, thermal, contamination, controls, software, and interface issues.\nAssess the feasibility of new measurement concepts and translate promising ideas into practical engineering solutions.\nValidate concepts through theoretical analysis, modeling, simulation, breadboard development, and experimental testing.\nWork with cross-functional teams to integrate core technologies into stable, reliable, automated, and cleanroom-compatible engineering solutions.\nSupport design reviews, technical risk management, supplier coordination, manufacturing readiness, equipment qualification, and system escalations.\nProvide technical guidance to design engineers, project teams, suppliers, and internal customers throughout the product-development lifecycle.\nCommunicate technical status, risks, issues, results, and next steps across engineering disciplines and management levels.\nDocument requirements, architectures, design specifications, interfaces, analyses, procedures, verification results, and training materials.\nPerform other duties as assigned.\nEducation and experience\nCandidates should meet one of the following combinations of education and relevant experience:\nPhD with at least 4 years of relevant experience.\nMaster’s degree with at least 8 years of relevant experience.\nBachelor’s degree with at least 12 years of relevant experience.\nA degree in optical engineering, photonics, physics, electrical engineering, mechanical engineering, systems engineering, biomedical engineering, imaging science, or a related technical field is preferred.\nRequired Qualifications\nExperience developing optical, electro-optical, or metrology systems for semiconductor equipment, scientific instrumentation, aerospace, medical devices, or another precision-hardware industry.\nDemonstrated ownership of an optical system or major subsystem from requirements definition through assembly, integration, testing, and verification.\nHands-on experience with optical alignment, laser systems, optical test equipment, sensors, detectors, cameras, or signal-detection systems.\nExperience with optical system design, tolerancing, alignment, calibration, and performance characterization.\nExperience performing photon-budget, radiometric, signal-chain, and signal-to-noise ratio calculations.\nKnowledge of lasers, optical sources, imaging and illumination systems, detectors, cameras, fibers, filters, coatings, and optomechanical components.\nExperience developing test methods, laboratory setups, calibration approaches, and data-analysis tools.\nAbility to troubleshoot failures in complex multidisciplinary systems using analytical models, experimental methods, and test data.\nAbility to develop and review theoretical models and validate concepts through analysis and breadboard testing.\nAbility to convert new technical concepts into practical engineering solutions.\nExperience documenting system requirements, designs, interfaces, test procedures, and verification results.\nExperience with data analysis and visualization using Python, MATLAB, LabVIEW, or equivalent tools.\nEffective written and verbal communication skills, including the ability to explain technical issues to engineers, scientists, management, suppliers, and internal customers.\nAbility to work independently while collaborating across optical, mechanical, electrical, controls, software, manufacturing, and supplier teams.\nSkills\nWorking at the cutting edge of technology requires solving new and complex problems through close collaboration. The successful candidate will work in a multidisciplinary environment with engineers, scientists, suppliers, and internal stakeholders.\nTo succeed in this role, the candidate should demonstrate:\nStrong theoretical and experimental knowledge of optical sensing, laser optics, imaging systems, detectors, electronics, and signal processing.\nSystem-level thinking and the ability to manage interfaces across multiple engineering disciplines.\nTechnical ownership, sound engineering judgment, and a record of delivering complex hardware.\nStructured problem-solving and root-cause-analysis skills.\nAbility to balance analytical rigor with hands-on laboratory execution.\nAbility to define and execute work from project objectives with limited supervision.\nAbility to communicate technical status, risks, tradeoffs, and recommendations clearly.\nProficiency with Microsoft Word, Excel, and PowerPoint.\nThe current base annual salary range for this role is currently:\n$143,063-209,825Pay scales are determined by role, level, location and alignment with market data.
