Job description

The Enterprise Network Virtualization Architect's role is to strategically plan and design data network virtual infrastructures that supports core organizational functions, assure high availability, and integrate numerous requirements into a common infrastructure. The enterprise data network consists of multiple local/wide area networks (LAN/WAN), wireless, VOIP, and enterprise data centers, to include software defined networks.

Provide networking technical expertise and leadership across the organization; strategic decision making, and multi year improvement project planning and design; Evaluate and develop hardware and protocol standards and solutions; Evaluate, manage & deploy software defined networks to include VMWare NSX technologies. Coordinate and lead teams to resolve technical issues and provide cost effective solutions to meet project and operational requirements. Establish effective working relationships with a multi-discipline team; communicate effectively and explain technical information with both a technical and non-technical audience. Prepare cost estimates to design and construct network infrastructure. Provide independent technical review, technical reports, system documentation, and performance metrics. Conduct operational studies to analyze network performance, and identify areas for improvements. Research and apply various network topologies. Prepare equipment specifications.

The position also works as part of a cross-functional team that deals with the full spectrum of technology and will fulfill the role of third level support for network technologies, providing training and direction to other technical staff.
