In Office Senior APAC Semiconductors Manufacturing Test Engineer Senior Software Engineer Fiber

Requirements

• 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 (wafer probers, optical probe/alignment fixtures, edge/grating coupler interfaces, RF probe cards) and software (automated test sequences, data acquisition, high-speed BERT/PAM4 test integration). • Lead the transfer of wafer-level test platforms from NPI to mass production, ensuring test repeatability, throughput, optical alignment stability, and reliability targets are met at volume. • Develop and document test process flows, work instructions, and training materials for production operators/technicians on optical probing and alignment procedures. • 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.
