Senior Photonics Test Engineer (ATE)

The Role As a member of OpenLight’s test engineering team, you will work closely with a team of experienced engineers in designing, implementing, and executing test solutions to validate the functionality of Silicon Photonics devices and Photonic Integrated Circuits (PIC), mainly at the wafer level on automated wafer probers. Strong background in optical and electrical device testing with experience in designing custom test hardware, ATE on the Advantest 93k platform, and programming in Python will elevate you above other candidates. The position is onsite at our Santa Clara, CA office and our San Jose, CA laboratory. What You Will Do Develop custom test hardware for wafer level testing on automated wafer probers Review and recommend potential equipment suppliers, write project proposals for our key suppliers Specify to our suppliers the designs of custom PCBAs and probe cards Specifying test algorithms to be implemented in the test automation code, and reviewing the results Proof of concept system design of alternative wafer test solutions Calibration of optical and RF probe cards Ordering and installing additional optical and RF test equipment, defining the test procedures, and verifying the test accuracy Optimizing test throughput and accuracy Reviewing test results for accuracy and debugging failures Operate the test stations for prototype runs and hand off production testing to our OSAT partners Test automation software in C++ or Java, test analysis software in Python Managing schedules for test execution, and communicating with internal and external customers on the test plans, results, and project status Your Background Includes Advanced degree in Physics or Electrical Engineering Test station hardware design experience ATE test experience, preferably on the Advantest 93k platform Hands on experience in a physics or electrical engineering lab or industry Programming experience in Python Strong analytical and problem-solving skills with the ability to work in a fast-paced, collaborative environment Initiative and ability to work independently About OpenLight OpenLight is growing as customer adoption and industry momentum continue to accelerate. The rapid growth of AI and cloud infrastructure is driving unprecedented demand for faster, more energy-efficient optical connectivity. We are addressing this challenge through a platform approach that simplifies the development of photonic integrated circuits (PICs) and accelerates industry adoption. As part of our team, you will contribute to technologies that enable AI and hyperscale data centers, high-speed optical communications, advanced sensing applications, next-generation photonic integration, and more. Our team is collaborative and fast-moving, and you will have the opportunity to make meaningful contributions across technology, operations, and business growth. If you are excited about solving challenging problems, advancing cutting-edge technology, and working with a highly collaborative team, we would love to hear from you.
