Semiconductor Test Engineer

Semiconductor Test Engineer

The Semiconductor Test Engineer is responsible for developing, optimizing, and sustaining test processes for semiconductor devices, with a strong focus on high power laser diode products. This role ensures reliable performance verification, smooth production flow, and effective transfer of new designs from R&D into manufacturing.

• Develop and maintain test processes for semiconductor devices, including laser diode chips, bars, arrays, and higher-level assemblies.
• Troubleshoot production line test issues, identify root causes, and implement engineering-driven corrective actions.
• Analyze test data to characterize device performance, identify trends, and drive continuous improvement.
• Validate and implement design changes, ensuring test readiness, documentation updates, and process stability.
• Collaborate with R&D, Product Development, and Manufacturing to support new product introduction (NPI) and ensure seamless test integration.
• Optimize test equipment, fixtures, and software, improving throughput, accuracy, and repeatability.
• Support yield improvement initiatives by identifying failure modes and recommending process or design enhancements.
• Maintain compliance with quality standards, safety requirements, and manufacturing best practices.

• Bachelor's degree in Electrical Engineering, Physics, Materials Science, or related field.
• Experience with semiconductor device testing, optoelectronics, or laser diode characterization.
• Strong analytical and troubleshooting skills, especially in high-volume manufacturing environments.
• Familiarity with automated test equipment (ATE), data acquisition systems, and statistical analysis tools.
• Ability to interpret electrical/optical test data and correlate results to device physics.
• Effective communication skills and the ability to work cross functionally.

• Experience with high power laser diodes or photonics components or discrete semiconductors.
• Knowledge of reliability testing, burn in processes, and failure analysis techniques.
• Programming experience (Python, LabVIEW, MATLAB, or similar) for test automation.
• Understanding of SPC, DOE, and other process control methodologies.
