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 You’ll Do
Test Development & Execution
- 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
Test Optimization & Yield Improvement
- 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
Cross-Functional Collaboration
- 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
Test Infrastructure & Hardware
- 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
What We’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
- Comfortable working cross-functionally in a fast-paced, evolving environment
What We Offer
- 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
