Junior Optical Test Engineer

Position Overview

We are seeking a Junior Optical Test Engineer (Long Term Contract) based in Sunnyvale, CA. In this role you will support the optical characterization of components and modules in AR/VR displays. The position involves conducting various tests—including measurements of roughness, thickness, flatness, color profile, image quality (MTF, PSF, etc.), and polarization—aligning optical components, demonstrating system performance to engineers and focus groups, designing test experiments and jigs, and performing statistical analysis on metrology data to correlate with performance metrics.

Key Responsibilities

• Characterize optical components and modules of AR/VR displays.
• Perform a range of tests across different components and modules, including:
  • Roughness or profile measurements
  • Thickness, flatness, and parallelism
  • Color profile or spectral response
  • Image quality metrics such as MTF, PSF, etc.
  • Polarization
• Align optical components for testing and characterization.
• Set up and manage demos for engineers and other focus groups to showcase system quality and performance.
• Create test experiments and jigs for optical component analysis.
• Collect and perform statistical analysis on metrology data to correlate with performance metrics.

Required Qualifications

• Hands-on experience with various optical metrology tools (MTF testers, interferometers, profilometers, spectrometers, ellipsometers, microscopes, etc.).
• Experience working in an optical laboratory and familiarity with best laboratory practices.
• Strong knowledge of geometrical and physical optics.
• Familiarity with imaging optics, image quality metrics, and optical metrology and characterization.
• Understanding of color measurement principles.
• Experience in test automation (instrument control and data collection) using LabView, MATLAB, or Python.
• Ability to script and prototype image analysis algorithms in MATLAB or Python.
• 1-3 years of relevant experience in industry or academia.

Preferred Qualifications

• Bachelor's degree in optics, optical engineering, physics, electrical engineering or a related field is preferred.
