Principal Engineer - Optical Development (DWDM, EDFAs, Raman amplifiers, and ROADMs)

Join Our Team at the Forefront of AI Infrastructure Innovation

As AI infrastructure expands exponentially, it is essential to redesign our optical systems to address increasing challenges related to cost, power, and rack space. To support this growth, we must simplify and design cost-efficient optical solutions. Join our innovative team and experience the excitement of complete product development from design to deployment.

Our team has delivered two Pioneer (now Pinnacle) Award products at Cisco.

Cisco Networking Engineering (CNE), formerly known as Distributed Systems Engineering (DSE), is a multi-billion-dollar business generating revenue from the Web, Service Provider Edge, Core, and Optical markets. The organization in India handles the development of high-end routers like ASR9000, NCS5500, NCS540, NCS560, NCS5700, and optical products such as NCS1010, NCS1014, NCS1004, NCS4000, and NCS2000 series. We offer exciting career opportunities for enthusiastic and experienced software professionals in India.
