• Serve as the primary technical contact for customers on quality and failure analysis issues related to Cisco's coherent optical pluggable products (e.g., QSFP-DD, OSFP form factors).

• Conduct detailed failure analysis using advanced diagnostic tools focused on coherent optics, including metrics such as BER, OSNR, Q Factor, and Forward Error Correction (FEC).

• Apply deep knowledge of coherent optical standards and protocols (400ZR, OpenZR+, OpenROADM, OTN) to troubleshoot and resolve complex customer issues.

• Collaborate with product development, manufacturing, and supply chain teams to communicate customer feedback and drive corrective and preventive actions.

• Support customer escalations with timely, clear, and technically accurate updates, emphasizing the unique aspects of coherent pluggable technology.

• Develop and deliver technical presentations and reports on failure trends, quality metrics, and improvement plans specific to coherent pluggable optics.

• Stay current with evolving coherent optical technologies, including Cisco's vertically integrated DSP, photonic integrated circuits, and pluggable module innovations.

• Review ORM/ORT failures and driver necessary corrective actions

Required Qualifications:

• Bachelor's degree in Electrical Engineering, Optical Engineering, Telecommunications, or related field; advanced degree preferred.

• Extensive experience (7+ years) in failure analysis and quality engineering focused on coherent optical pluggable products or digital coherent optics.

• Strong understanding of coherent optical networking standards and protocols, including 400ZR, OpenZR+, OpenROADM, and OTN.

• Hands-on experience with coherent optical transceiver technologies, including QSFP-DD, OSFP, and CFP2 form factors.

• Proficiency in analyzing coherent optics performance parameters such as BER, OSNR, Q Factor, FEC, and chromatic dispersion.

• Proven ability to analyze complex failure data and develop actionable insights to improve product quality and network performance.

• Excellent customer-facing communication skills with the ability to explain complex coherent optical concepts clearly.

• Experience working with Cisco's coherent optical product portfolio and routed optical networking solutions is highly desirable.

• Strong problem-solving skills, attention to detail, and a proactive approach to quality improvement.
