Director of Silicon Test Engineering - San Jose, United States
Originally posted 23 March 2026 by the employer.
Lead test development for silicon photonics and semiconductor products, supporting high-volume production.
About the role
As Director of Silicon Test Engineering, you will lead the strategy and execution of test development for Lumilens' silicon photonics and semiconductor products. You will be responsible for building scalable, high-quality test solutions from characterization through high-volume production.
What you'll do
- Define and drive the end-to-end silicon test strategy from characterization to wafer sort and final test
- Lead development of ATE test solutions on platforms such as Advantest 93K and/or Teradyne
- Optimize test flows to reduce test time, improve coverage, and lower cost of test
- Partner with product and process engineering to analyze yield data and drive continuous improvement
- Collaborate with design and DFT teams to ensure testability and coverage are built into products early
- Oversee development of high-speed test hardware and interfaces for advanced silicon photonics devices
What you'll need
- 10+ years of experience in semiconductor or silicon photonics test engineering
- 5+ years of leadership experience managing engineering teams or complex test programs
- Deep expertise in ATE test development (Advantest 93K and/or Teradyne platforms)
- Strong background in silicon validation, production test, DFT/DFM, and high-speed digital or mixed-signal testing
- Experience optimizing test time, coverage, yield, and cost in high-volume manufacturing
- Proficiency in programming/scripting (C/C++, Python, Perl) and Linux environments
