Test Engineer / Senior Test Engineer

Job responsibilities:

• Define and implement die-level and wafer-level test solutions in collaboration with design and product teams.
• Develop production test solutions for PIC components to ensure manufacturability and scalability.
• Develop and execute design verification tests, analyze results, and provide feedback to improve device performance.
• Optimize and standardize test and analysis methodologies to improve repeatability and accuracy.
• Bring up, manage, and operate automated wafer-level test (WLT) probers and chip level handlers for PIC devices, including passive and active optical and RF components.
• Perform routine setup calibrations and ensure quality control throughout the test process.
• Identify and mitigate test challenges to ensure timely, efficient execution of large-scale technical projects.
• Take ownership of collecting high-quality measurement data and preparing measurement reports for optical, electrical, and electro-optical tests.
• Analyze test results, perform Gauge Repeatability and Reproducibility (GR&R) studies, troubleshoot issues, and recommend improvements.
• Document test procedures, results, and technical reports to maintain a comprehensive knowledge base.

Job requirement:

• Bachelor's or higher degree in Electrical Engineering, Photonics, Physics, or a related field.
• 2–5+ years of experience testing and characterizing photonic or semiconductor devices (fresh graduates with strong academic or project experience in photonics/semiconductor testing are also encouraged to apply).
• Solid technical understanding of, and ability to perform, optical, RF, or electro-optic measurements.
• Strong proficiency in Python programming is required, with hands-on experience building test automation scripts and instrument interfacing/control (e.g., SCPI, VISA, GPIB).
• Strong analytical and problem-solving skills, with close attention to detail, diligent note-taking, and precise report writing.
• Knowledge of semiconductor fabrication processes and photonics principles is a plus.
• Ability to work well in a team environment and participate in cross-functional activities.
• Experience interfacing with or managing foundries or OSATs is a plus.
