Meet the Team

Join Cisco's COG business unit as part of our dynamic Test Development team, where innovation and collaboration drive the success of our optical transceiver products. As an ATE Test Development Engineer, you'll work closely with cross-functional teams-including design, product engineering, quality, and applications-to develop, validate, and optimize production tests from NPI through the product lifecycle. Our team thrives on solving complex technical challenges, improving test coverage, and ensuring high-quality, reliable products reach our customers worldwide.

Your Impact

As an ATE 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.

• Develop, validate, and characterize ATE production tests for optical transceiver products at wafer and CoCoS levels.
• Influence NPI/design phases to optimize DFT/DFM, test coverage, calibration, and architecture decisions.
• Monitor and sustain product flow in production with offshore 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 process improvement.

Minimum Qualifications

• Minimum MSEE with 5+ years or BSEE with 8+ years of relevant industry experience; experience with semiconductor processes, optical/photonic components, and familiarity with QSFP MSA standards; overseas production management preferred.
• Hands-on knowledge of ATE platforms (Advantest 93k, Tel, Teradyne uFlex), automated test solutions (Python), and a wide range of bench equipment (BERTs, optical switches, oscilloscopes, power meters, OSAs).
• Strong understanding of PCB design and review, configuration management systems (Agile/Omnify), and general FAB/semiconductor process fundamentals.
• Proficiency with statistical analysis methods and tools (JMP, Data Conductor, Data Power, Power BI), including GR&R, CpK, correlation, and SPC process control.
• Proven ability to solve complex problems, influence cross-functional teams, and foster a collaborative, productive working environment.
