Preferred Qualifications

MS Electical Engineering or similar degree

5+ years relative semiconductor industry experience working with silicon/optical/photonic wafers

Ability to solve complex problems, influence cross-functional teams, and foster a collaborative, productive working environment.

## Description

Join Cisco's Supply Chain Product Operations as part of our dynamic Test Development team, where innovation and collaboration drive the success of our optical transceiver products. As a Wafer Test Development Engineer, you'll work closely with cross-functional teams-including design, product engineering, quality, and applications-to develop, validate, and optimize production testing of our silicon wafers from NPI through the product lifecycle.

Your Impact

As the Wafer Test Engineer, you will play a key role in ensuring the quality, performance, and manufacturability of optical transceiver products. You will lead test development, validation, and characterization efforts from NPI through production, driving design-for-test decisions and optimizing test coverage. By analyzing test data, setting product limits, and collaborating with cross-functional teams-including product engineering, manufacturing, design, and applications-you will influence product performance, yield, and cost while supporting continuous improvement and failure analysis initiatives.

Responsibilities include (but not limited to):

 * Develop, validate, and troubleshoot ATE wafer production testing for optical transceiver products.
 * Influence NPI/design process to optimize DFT/DFM, test coverage, calibration, and architecture.
 * Monitor and sustain product flow in offshore production manufacturing to meet cost, delivery, and yield targets.
 * Analyze characterization, qualification, and production data to set test limits, optimize yield, and improve test efficiency.
 * Provide cross-functional support for product debug, failure analysis, and continuous test improvement.
