Meet the Team

Cisco's Client Optics Group (COG) designs & delivers the high-speed optical transceivers, and platforms that power Cisco's core data center networking solutions. We specialize in the design and integration of cutting-edge IM/DD optics and silicon photonic platforms that enable customers to deploy industry-leading optical technologies within data center 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) being developed in the industry.

You will work with Cisco's best-in-class Silicon Photonics team. Our team is responsible for driving the development and optimization of optical transceivers & modules (800G,1.6T & beyond) that seamlessly integrate with Cisco's routing, switching, and datacenter platforms, enabling customers to build scalable, high-performance networks that support emerging technologies including AI/ML workloads, and next-generation data center architectures.

We are looking for a talented and experienced Design Verification Lead to join our team and drive verification of Cisco's silicon photonics driver integrated circuits for the next generation of products for 100/200/400G per Lambda solutions.

Your Impact

Assist in RTL/netlist‑to‑GDSII implementation for block‑level and full‑chip designs in advanced technology nodes.
Support digital implementation flows and collaborate with EDA tool vendors to debug issues.
Support in developing hierarchical floorplans, macro placement, I/O planning, congestion, timing, and power distribution.
