Lumilens
Senior Silicon Photonics Test Engineer (NPI)
Singapore. Posted 3 months ago
The role
This person will lead the development of wafer-level test solutions for NPO and CPO products from NPI through high-volume production. They will architect testers for photonic ICs and manage the full lifecycle of test development.
What you will do
- Own and lead the full NPI cycle for silicon photonics wafer level opto-electrical test
- Design, develop, and qualify wafer-level test systems/testers for NPO/CPO silicon photonics products
- Own and lead the tester RFQ process
- Develop test hardware including wafer probers, optical probe/alignment fixtures, edge/grating coupler interfaces, and RF probe cards
- Develop software including automated test sequences, data acquisition, and high-speed BERT/PAM4 test integration
- Lead the transfer of wafer-level test platforms from NPI to mass production
- Develop and document test process flows, work instructions, and training materials
- Partner with manufacturing, quality, and equipment vendors to qualify wafer-level testers and optical probers
- Provide ongoing engineering support to resolve test-related yield, throughput, or equipment issues
Required qualifications
- Bachelor’s degree or higher in Electrical Engineering, Optical Engineering, Photonics, Physics, or related field
- 5+ years of experience in semiconductor or silicon photonics test engineering
- Hands-on wafer-level test development experience
- Proven track record of taking a test platform from NPI through production transfer at volume
- Experience with wafer-level optical probing/alignment systems (active alignment, fiber array probing)
- Experience with automated test equipment (ATE)
- Familiarity with high-speed electrical test (SerDes, PAM4/NRZ, BERT)
- Familiarity with electro-optical measurement instruments (optical power meters, tunable lasers, source meters, network/spectrum analyzers, BERT)
- Working knowledge of DOE, SPC, Gauge R&R, and yield/binning analysis methodologies
Nice to have
- Understanding of silicon photonics PIC characterization
- Understanding of CPO/NPO packaging architecture (die-to-package interconnect, thermal/optical co-design constraints)
- Prior experience with relevant products
