TL;DR · Senior Electro-Optical Systems Engineer

The Senior Electro-Optical Systems Engineer joins the Non-Product Metrology group to develop precision optical and electro-optical metrology systems for extreme ultraviolet sources in next-generation photolithography equipment. This role involves owning major metrology subsystems from requirements definition through design, procurement, assembly, integration, testing, and release. You will build sensing systems using lasers, illumination and imaging optics, detectors, cameras, fibers, filters, coatings, and optomechanical assemblies. Key responsibilities include performing photon-budget and signal-to-noise ratio calculations, conducting optical performance and stray-light analyses, and integrating hardware with low-voltage electronics, motors, and thermal-management systems. You will utilize Python, MATLAB, and LabVIEW for data analysis and visualization. The work focuses on enabling EUV source learning, power scaling, and stable operation by solving complex multidisciplinary problems in light production and measurement.

What you'll do

  • Translate stakeholder needs into metrology requirements, subsystem specifications, interface definitions, and verification plans.
  • Lead the design, development, and integration of optical and electro-optical metrology systems for EUV sources.
  • Develop sensing systems using lasers, imaging optics, detectors, cameras, fibers, and signal-processing hardware.
  • Perform photon-budget, radiometric, and signal-to-noise ratio calculations to account for source output and system noise.
  • Own metrology subsystems through component selection, supplier engagement, procurement, assembly, and qualification.
  • Integrate optical hardware with low-voltage electronics, motors, precision mechanisms, and thermal-management systems.
  • Develop laboratory test benches, diagnostic tools, calibration methods, and automated data-analysis tools.
  • Lead root-cause investigations for optical, electrical, mechanical, thermal, and software issues in complex systems.

What we're looking for

  • PhD with 4 years, Master’s with 8 years, or Bachelor’s with 12 years of relevant experience.
  • Degree in optical engineering, photonics, physics, electrical engineering, mechanical engineering, systems engineering, biomedical engineering, imaging science, or a related technical field (preferred).
  • Experience developing optical, electro-optical, or metrology systems for semiconductor equipment, scientific instrumentation, aerospace, medical devices, or precision-hardware industries.
  • 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, sensors, detectors, cameras, and signal-detection systems.
  • Experience performing photon-budget, radiometric, signal-chain, and signal-to-noise ratio calculations.
  • Experience with data analysis and visualization using Python, MATLAB, LabVIEW, or equivalent tools.
  • Legal authorization to access controlled technology as defined by United States Export Administration Regulations.
