San Diego Senior Optical Sensing Engineer at ASML in San Diego, CA

San Diego Senior Optical Sensing Engineer

Location: San Diego, CA, USA

Introduction to the Job

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 comprehensive standalone EUV source qualification in San Diego by developing and owning internal EUV source metrology tools.

The 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.

This 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.

Role and responsibilities

• Translate equipment, system, and stakeholder needs into metrology requirements, subsystem specifications, interface definitions, performance budgets, and verification plans.

• Lead 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.

• Develop sensing systems involving lasers, illumination and imaging optics, detectors, cameras, fibers, filters, coatings, optomechanical assemblies, and signal-processing hardware.

• Develop specifications for light-emitting, light-delivery, and light-sensing modules in accordance with system-level and cross-functional requirements.

• Perform 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.

• Conduct optical performance, tolerancing, stray-light, beam-propagation, alignment, calibration, and image- or signal-quality analyses.

• Apply knowledge of optics, sensors, electronics, algorithms, software, and data analysis to improve metrology performance.

• Own metrology subsystems through component selection, supplier engagement, procurement, assembly, alignment, integration, testing, qualification, and release.

• Integrate optical hardware with low-voltage electronics, motors, analog sensors, precision mechanisms, controls, software, motion systems, and thermal-management hardware.

• Develop laboratory test benches, diagnostic tools, fixtures, calibration methods, test procedures, acceptance criteria, and automated data-analysis tools.

• Plan and execute laboratory and cleanroom testing for design validation and verification.

• Correlate analytical and numerical predictions with measured results and resolve performance gaps.

• Lead integration and troubleshooting activities to verify that metrology systems function as designed within the EUV light source.

• Lead root-cause investigations involving optical, electrical, mechanical, thermal, contamination, controls, software, and interface issues.

• Assess the feasibility of new measurement concepts and translate promising ideas into practical engineering solutions.

• Validate concepts through theoretical analysis, modeling, simulation, breadboard development, and experimental testing.

• Work with cross-functional teams to integrate core technologies into stable, reliable, automated, and cleanroom-compatible engineering solutions.

• Support design reviews, technical risk management, supplier coordination, manufacturing readiness, equipment qualification, and system escalations.

• Provide technical guidance to design engineers, project teams, suppliers, and internal customers throughout the product-development lifecycle.

• Communicate technical status, risks, issues, results, and next steps across engineering disciplines and management levels.

• Document requirements, architectures, design specifications, interfaces, analyses, procedures, verification results, and training materials.

• Perform other duties as assigned.

Required Qualifications

• Experience developing optical, electro-optical, or metrology systems for semiconductor equipment, scientific instrumentation, aerospace, medical devices, or another precision-hardware industry.

• Demonstrated ownership of an optical system or major subsystem from requirements definition through assembly, integration, testing, and verification.

• Hands-on experience with optical alignment, laser systems, optical test equipment, sensors, detectors, cameras, or signal-detection systems.

• Experience with optical system design, tolerancing, alignment, calibration, and performance characterization.

• Experience performing photon-budget, radiometric, signal-chain, and signal-to-noise ratio calculations.

• Knowledge of lasers, optical sources, imaging and illumination systems, detectors, cameras, fibers, filters, coatings, and optomechanical components.

• Experience developing test methods, laboratory setups, calibration approaches, and data-analysis tools.

• Ability to troubleshoot failures in complex multidisciplinary systems using analytical models, experimental methods, and test data.

• Ability to develop and review theoretical models and validate concepts through analysis and breadboard testing.
