TL;DR · Senior Optical Sensing Engineer

The Senior Optical Sensing Engineer joins the YieldStar Sensor Group to develop advanced sensor technology for semiconductor metrology systems. This role involves designing and improving optical sensors that operate in complex environments by integrating light sources, detectors, fiber optics, electronics, and signal-processing software. Key responsibilities include modeling optical systems using CODE V, Zemax, or comparable software, performing physical optics simulations, and developing polarization models. The engineer will build, align, test, and troubleshoot complex photonic systems while designing test stands and analyzing sensor data using MATLAB. Required expertise includes optical design, tolerancing, and hardware integration involving relay optics, objectives, and cameras. The position addresses technical challenges in semiconductor manufacturing by improving the accuracy and performance of equipment used by microchip manufacturers to ensure high-quality production.

What you'll do

  • Design and model optical systems using CODE V, Zemax, or comparable optical design software.
  • Perform optical tolerancing, wave-propagation modeling, and partial-coherence calculations.
  • Develop polarization models and error budgets to evaluate optical performance and system risks.
  • Process and analyze sensor data using MATLAB or comparable data-analysis tools.
  • Build, align, test, qualify, and troubleshoot complex optical and photonic sensor systems.
  • Design test stands including concepts, error budgets, hardware selection, and system realization.
  • Investigate technical issues to determine root causes and support new product introduction.
  • Provide cleanroom engineering support to identify root causes during customer escalations.

What we're looking for

  • Obtain a bachelor’s degree in optical engineering, physics, or a related technical field, plus four years of relevant experience.
  • Obtain a master’s degree in optical engineering, physics, or a related technical field, plus two years of relevant experience.
  • Obtain a doctoral degree in optical engineering, physics, or a related technical field.
  • Perform optical design and tolerancing using CODE V, Zemax, or comparable software.
  • Perform physical optics modeling using FRED, MATLAB, or comparable simulation software.
  • Execute optical sensor alignment using collimators, mechanical measurement tools, or interferometers.
  • Design optical metrology tests, develop test stands, and perform hardware integration.
  • Possess legal authorization to access controlled technology as defined in the United States Export Administration Regulations.
