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: 1. Define and implement wafer-level test plans for PIC wafers, including active and passive optical components. 2. Analyze large-scale wafer test datasets to identify performance trends and yield detractors. Drive root-cause analysis for yield excursions. 3. 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. 4. Partner with contract manufacturers to deploy alternative test solutions that reduce lead times and increase throughput without compromising quality. 5. New Product Introduction (NPI): Drive the "DEV" to "PROD" release states by validating test correlation between bench-top characterization and automated wafer probers. 6. 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.
