General description

Provision, deploy, manage, and program networks with software-defined networking. In this centralized approach to network management, the underlying network infrastructure is abstracted from applications. Software Defined Networks (SDN) provides choice in automation and programmability across data centers SD-LAN, campuses, and wide-area networks SD-WAN.
The role of SDN in cloud computing lets users respond quickly to changes. SDN management makes network configuration more efficient and improves network performance and monitoring. Candidate will be responsible to design new solution to fulfill customer requirements and to execute functionality testing and implementation of the developed solution. The role includes consultancy with operational teams, analysis of customer demands, conversion of the requirements into a technical specification.


  • Design, develop, and enable deployment of a software-defined network architecture for the global compute platform.
