About the role
As a Silicon Test Engineer , you will be responsible for developing and executing test solutions for Lumilens’ silicon photonics and semiconductor products. You will work across characterization, wafer sort, and final test to ensure robust coverage, high product quality, and efficient manufacturing at scale. This is a hands-on role focused on building and optimizing test infrastructure, working closely with design, product, and operations teams to enable successful product ramps and ongoing production performance.
What they're looking for
- 8–12+ years of experience in semiconductor or silicon photonics test engineering
- Strong experience with ATE platforms such as Advantest 93K and/or Teradyne
- Background in silicon validation, production test, DFT/DFM, and high-speed or mixed-signal testing
- Experience optimizing test time, coverage, yield, and cost in a manufacturing environment
- Proficiency in scripting/programming (C/C++, Python, or similar) and Linux-based environments
- Strong analytical and problem-solving skills, with an ability to work through complex technical challenges
