Product Engineer - Wafer Test

Job Description

The Product Engineer will focus on the development, validation, and optimization of wafer-level optical and electrical test processes and ensure world-class yield, reliability and performance for transitioning Cisco's next-generation Photonic Integrated Circuits (PICs) from design to high-volume production to power our 400G/800G/1.2T coherent modules.

Key Essential Functions

• Define and implement wafer-level test plans for PIC wafers, including active and passive optical components.
• Analyze large-scale wafer test datasets to identify performance trends and yield detractors. Drive root-cause analysis for yield excursions.
• Lead Failure Analysis Reports (FAR) for wafer-level rejects. Coordinate with the foundry, design and process teams to resolve failures caused by wafer-level anomalies.
• Partner with contract manufacturers to deploy alternative test solutions that reduce lead times and increase throughput without compromising quality.
• New Product Introduction (NPI): Drive the "DEV" to "PROD" release states by validating test correlation between bench-top characterization and automated wafer probers.
• Cross-Functional Collaboration: Work closely with PIC Design, DSP Firmware, and Hardware teams to define Guard band and spec limits that ensure robust field performance.

Minimum Qualifications, Experience, Skills, Education And Certifications

• Education: BS/MS in Electrical Engineering, Optical Physics, Physics, or Semiconductor Manufacturing.
• 3+ years of experience in optical or semiconductor industries, focusing on wafer level probe test.
• Good understanding of PIC wafer testing on various optical components, including lasers, modulators, detectors and waveguides.
• Solid experience with wafer-probing equipment, automated test equipment (ATE), and cleanroom protocols.
• Proficiency in statistical analysis software (JMP, Minitab) and database management (SQL/SQLite).
• Ability to distill complex technical failures into concise executive summaries and Supplier Corrective Action Requests (SCARs).
• Extensive experience managing high-volume manufacturing in Asia (Thailand/Malaysia).

Primary Work Location: Pathum Thani, Thailand
