• Drive the development of new technologies to cover I-line to IR wavelength light sources, objectives, and imaging optics.

• Oversee design validation through lab testing, metrology, and performance metrics (e.g., MTF, SNR, wavefront error).

• Mentor junior engineers and establish best practices in optical design documentation, simulation, and prototyping.

• Interface with product management and customers to align optical capabilities with market needs and manufacturing constraints.

Qualifications

Qualifications:

• Master's or PhD in Optical Engineering, Physics, or a related field.

• 15+ years of experience in optical system design, preferably in semiconductor metrology or inspection.

• Expertise in optical modeling tools (e.g., Zemax, Code V, LightTools).

• Strong understanding of geometrical and physical optics, optical system design, tolerancing, and manufacturability.

• Experience with laser-based systems, spectroscopic techniques, and precision alignment.

• Proven leadership in managing technical teams and delivering complex projects.

Preferred Skills:

• Experience writing requirements, specifications, and working with suppliers to produce custom optics.

• Experience with optical metrology and the testing of optical systems.

• Background in integrating optics with mechanics, motion control, sensors, and embedded systems.

• Experience modeling stray light, ghost reflections and calculating light budgets

• Familiarity with semiconductor process control, semiconductor inspection and metrology techniques.

• Familiarity with next generation logic and memory device architectures such as especially in Gate All Around and High Bandwidth Memory architectures

• Experience working in cleanrooms and understanding of cleanroom protocols.
