NETWORK ARCHITECT - CHB_03_MN4

Byte Ratio•Herndon, VA

About The Position

Work as part of a collaborative, multidisciplinary team supporting the U.S. Government, providing technical subject matter expertise in network engineering and communications modeling. Translate business requirements into telecommunications requirements, designs, and orders for LAN, MAN, WAN, voice, and video systems, while accounting for the Agency network’s INFOSEC and COMSEC requirements. Perform complex network designs across multiple technologies and technology layers within an enterprise network. Evaluate new technologies and recommend how to integrate them into existing infrastructure. Plan designs and configurations that support effective integration and optimal performance, using knowledge of network performance characteristics and interconnection points. Provide engineering and design support for tactical communications systems. Research existing technologies and apply COTS/GOTS systems to develop secure voice and data network infrastructure. Integrate system designs with network architecture, test and deploy designs at tactical CONUS and OCONUS locations, and provide post-design installation, configuration, tier III, and O&M support for enterprise and field-deployed systems. Create simulated networks for testing applications over low-bandwidth links; troubleshoot connectivity; install and configure wide-area links using RF communications such as satellite, cellular, and microwave; and configure, test, and maintain infrastructure connected to enterprise architecture. Knowledge of network intrusion detection is required.
