Senior Silicon Photonics Test Engineer: NPI to Production

Lumilens; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Lumilens is hiring a Senior Silicon Photonics Test Engineer to lead wafer-level test development for Near-Package Optics and Co-Packaged Optics products from NPI to high-volume production. You will own test system architecture, tester design, and integration with die/ASIC components to ensure sustained yield and quality.

You will drive RFQ activities, develop test hardware and software, and mentor production teams on probing and alignment procedures, with close collaboration across manufacturing

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, with 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) and automated test equipment (ATE).
• Familiarity with high-speed electrical test (SerDes, PAM4/NRZ, BERT) relevant to co-packaged optics electrical interfaces.
• 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.
• Understanding of silicon photonics PIC characterization is a plus.
• Understanding of CPO/NPO packaging architecture (die-to-package interconnect, thermal/optical co-design constraints), prior experience with relevant products is a plus.

Responsibilities

• 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 and software and data acquisition for high-speed tests.
• Lead the transfer of wafer-level test platforms from NPI to mass production, ensuring repeatability and reliability at volume.
• Develop and document test process flows, work instructions, and training materials for production operators/technicians.
• Partner with manufacturing, quality, and equipment vendors to qualify wafer-level testers and optical probers on the production floor.
• Provide ongoing engineering support to resolve test-related yield, throughput, or equipment issues in NPO/CPO production.
