Job summary

Lumilens in San Jose, CA seeks a Silicon Test Engineer to develop and execute test solutions for silicon photonics and semiconductor products, working across characterization, wafer sort, and final test to ensure high quality and scalable manufacturing.

You will build and optimize test infrastructure, collaborate with design, product, and operations teams, and help enable successful product ramps and production performance.

Qualifications

• 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.

Responsibilities

• Develop and implement silicon test solutions from characterization through wafer sort and final test.
• Create and maintain ATE test programs on platforms such as Advantest 93K and/or Teradyne.
• Translate design and DFT requirements into scalable, production-ready test solutions.
• Support new product introduction (NPI) and ensure smooth transition into high-volume manufacturing.
• Optimize test flows to improve coverage, reduce test time, and lower cost of test.
• Analyze yield and test data to identify trends and drive continuous improvement.
• Debug test failures and identify root causes across product, test, and process.
• Strengthen screening coverage to ensure only high-quality devices ship to customers.
• Partner closely with design, product, and process engineering teams to ensure testability is built in early.
• Support test plan reviews and collaborate on coverage, performance, and reliability requirements.
• Work with operations teams to ensure test readiness for production ramps.
• Contribute to development of high-speed test hardware and interfaces for photonics devices.
• Ensure test solutions meet performance requirements for high-speed and mixed-signal applications.
• Support improvements in test methodologies as product complexity increases.
