Experience designing and analyzing complex optical systems.
Familiarity with optical simulation and design tools such as Zemax, CODE V, FRED, LightTools, or equivalent.
Experience with laboratory optical alignment, characterization, and troubleshooting.
Strong analytical and problem-solving skills.
Excellent written and verbal communication skills.

Responsibilities

Design and develop optical systems for semiconductor metrology applications, including imaging, spectroscopy, scatterometry, and ellipsometry.
Define optical architectures, component specifications, tolerances, and performance budgets.
Develop and optimize illumination, collection, and imaging channels for measurement and pattern recognition applications.
Perform optical modeling and simulation using Zemax, CODE V, FRED, or equivalent tools.
Analyze optical performance, image quality, polarization effects, signal-to-noise ratio, stray light, aberrations, and throughput.
Support prototype assembly, optical alignment, calibration, and system integration.
Design and execute experiments to validate optical subsystem performance and correlate results with system-level requirements.
Investigate and resolve optical performance issues identified during development, manufacturing, or customer deployment.
Collaborate with suppliers to specify and qualify lenses, filters, light sources, detectors, gratings, and other optical components.
Document designs, test plans, and engineering results, and participate in technical design reviews.
Support transfer of optical designs into manufacturing and field deployment.
