Cisco’s Client Optics Group (COG) designs and delivers high‑speed optical transceivers and platforms that power Cisco's core data center networking solutions. We specialize in the design and integration of innovative IM/DD optics and silicon photonic platforms that enable customers to deploy industry‑leading optical technologies within data centers with unprecedented speed, capacity, and reliability.

Come join us and take part in shaping COG’s ground‑breaking optical solutions by designing, developing, and testing some of the most advanced pluggable and co‑packaged optics (CPO).

As an Optical Component Test Engineer, you will develop and perform test and failure analysis for optical components used in Cisco silicon photonics transceivers.

• Work as part of a team responsible for designing and sourcing optical components for silicon photonics, from development through production, including characterization and qualification of these components.
• Work with senior engineers and scientists on the characterization of optical components such as lasers, isolators, lenses, fiber connectors, and more.
• Work as part of a team to develop and build test apparatus as the need arises to characterize needed components.
• Perform failure analysis and work to determine root cause and set up corrective actions.

• Bachelor’s degree + 5 years of related experience, or Master’s degree + 3 years of related experience, or PhD + 0 years of related experience.
• Optical testing, semiconductor testing, or similar measurement experience.

• Knowledge of classical optics and fiber optics.
• Basic understanding of laser theory.
• Experience programming in C#, .NET, Python, or another OOP language.
• Ability to collect and analyze complex datasets (e.g., experience with JMP, Data Conductor, or similar data analysis tools).
• Experience with automated instrument/machine control and machine vision is a plus.
