Silicon Test Engineer

The role

You will develop and execute test solutions for silicon photonics and semiconductor products. You will work across characterization, wafer sort, and final test to ensure product quality and efficient manufacturing.

What you will do

• Develop and implement silicon test solutions from characterization through wafer sort and final test
• Create and maintain ATE test programs on Advantest 93K and/or Teradyne platforms
• Translate design and DFT requirements into scalable, production-ready test solutions
• Support new product introduction and 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
• Strengthen screening coverage
• Partner with design, product, and process engineering teams
• Contribute to development of high-speed test hardware and interfaces

Required 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)
• Proficiency in Linux-based environments
• Strong analytical and problem-solving skills

Benefits

• Competitive compensation commensurate with experience
• Comprehensive health benefits
• Exposure to cutting-edge photonics technology and advanced manufacturing environments
• Opportunity to work closely with cross-functional teams across engineering, product, and operations
• A collaborative environment where individual contributors can make a direct and measurable impact
