• A strong foundation in optics and photonics, including geometrical optics, optical system design, spectroscopy, or imaging
• A solid understanding of classical mechanics, including dynamics, kinematics, and force analysis
• Experience in experimental work and laboratory measurements, with a careful and systematic approach to data collection
• Familiarity with semiconductor materials, surface properties, reflectance, and the physical origins of defects in dies
• Experience in precision measurement, including traceability, uncertainty budgets, and calibration of optical or mechanical instruments
• Strong communication and collaboration skills, with the ability to translate complex physical concepts into clear language for engineers, developers, and management
• A structured and precise working style, applying scientific rigour to documentation, measurement, and experimental design

We offer:
