NETWORK SYSTEMS ENGINEER III

Transcription

1 NETWORK SYSTEMS ENGINEER III DEFINITION Under direction, provides technical support for the County s infrastructure of Local Area Networks (LANs), Wide Area Network (WAN) and other related data network telecommunications equipment, including: Routers, Switches, Virtual Private Networks (VPNs) and Firewalls; performs complex LAN/WAN technical tasks to develop and maintain the County s network infrastructure; manages complex and large technical projects; assigns work and trains assigned staff; formulates network integration solutions; facilitates communication among all stakeholders to define project scope, set priorities, sequence implementation, and ensure appropriate monitoring of technology solutions. DISTINGUISHING CHARACTERISTICS Network Systems Engineer III is the advanced level of the series. This level performs complex LAN/WAN technical tasks to develop and maintain the County s network infrastructure to achieve high network availability and ensure that it is consistently measured and monitored to minimize administrative costs. Network Systems Engineer III designs network integrity, reliability, and availability into the infrastructure, participates in standards organizations, develops standards specifications for use throughout the network, conducts research and development into new technologies, advances the state of the county network services, actively manages complex and large technical projects, and mentors and develops staff skills to successfully complete projects. This level is responsible for gathering information from technical reference manuals, hardware specifications and trouble-shooting guides to formulate network integration solutions, and understand and carry out complicated written and oral instructions. Network Systems Engineer III serves as project coordinator to ensure that the Data Networks Team works with internal customers to develop network solution requirements during the scope definition phase of projects; works with the IT Network Manager, Communications Engineer, and the County Chief Security and Privacy Officer or designee to understand project priorities and help sequence network engineering components accordingly; and coordinates with Network Operations Center to ensure appropriate monitoring of new network solution is included as part of the implementation and roll out. Network Systems Engineer III is distinguished from Network Systems Engineer II in that the latter is the journey level of the series with responsibility for complex network trouble-shooting tasks utilizing high level network trouble-shooting tools such as Network Protocol Analyzers, PING and Trace routes utilities and for all aspects of network data communications equipment and services, and primary responsibility for evaluating and testing new technology related to data communications and its associated Operating System (IOS) levels. The Network Systems Engineer series is distinguished from other professional Information Technology positions in that this position is focused on network data communications technologies, and LAN/WAN infrastructure design, configuration, installation, maintenance, network capacity planning and other data network specific functions.

2 The Network Systems Engineer series is distinguished from the Information Technology Support Technician series in that the former is focused on the practical application of network engineering and design and the latter is focused on data networks hardware integration and interconnectivity.
