• Collaborate with design and manufacturing teams to develop test software
• Perform functional, regression, and performance testing on Layer 1 and Layer 2 network systems
• Configure and use traffic generators like IXIA to simulate network environments
• Ensure test and manufacturing software modifications follow QMS requirements
• Develop, assemble, validate, and release testers for production
• Analyze test results to ensure compliance with performance specifications
• Execute continuous improvement plans for test yield, cycle time, and throughput
• Collaborate with design teams to ensure DFM and DFT guidelines are met
• Generate comprehensive test reports for stakeholders

Required qualifications

• Bachelor’s degree in Electrical Engineering, Industrial Engineering, Physics, Computer Science, or related field
• 7 years hand-on experience in software testing and test automation of optical transceiver products including Silicon Photonics
• In-depth technical knowledge and hands-on experience in yield analysis, problem solving, and implementation of manufacturing processes
• Familiarity with processor communication interfaces and test automation tools
• Data query and data analysis skills, using statistical tools and techniques
• In-depth understanding and practical experience in SPC, GR&R, tester correlation, and report generation
• Ability to write or adapt scripts for automation (Python, LabVIEW, Visual Basic)
